Bill Belichick

William Stephen Belichick (born April 16, 1952) is an American sports analyst and football coach. Widely regarded as one of the greatest head coaches of all time,  he holds numerous coaching records, including the record of most Super Bowl wins (six) as a head coach, all with the New England Patriots, along with two more during his time as the defensive coordinator of the New York Giants, for a record eight combined total Super Bowl victories as coach and coordinator. A renowned American football historian, Belichick is often referred to as a "student of the game" with a deep knowledge of the intricacies of each player position. During his tenure with the Patriots, Belichick was a central figure as the head coach and de facto general manager during the franchise's dynasty from 2001 to 2019.

Belichick is a descendant of the Bill Parcells coaching tree. He began his coaching career in 1975 as an assistant for the Baltimore Colts and became the defensive coordinator for New York Giants head coach Bill Parcells by 1985. Parcells and Belichick won two Super Bowls together before Belichick left to become the head coach of the Cleveland Browns in 1991. He remained in Cleveland for five seasons but was fired following the team's 1995 season. Belichick rejoined Parcells, first in New England where the team lost Super Bowl XXXI, and later with the New York Jets. After being named head coach of the Jets, Belichick resigned after only one day on the job to accept the head coaching job for the Patriots on January 27, 2000. In 24 seasons under Belichick, the Patriots won 17 AFC East division titles, made 13 appearances in the AFC Championship Game, and appeared in nine Super Bowls, with a record six wins. Overall, Belichick has won eight Super Bowl titles (the most of any individual in NFL history) and finished as runner-up four times from his combined time as an assistant and head coach.

At the time Belichick left the Patriots, he was the NFL's longest-tenured active head coach. Belichick has the most playoff coaching wins all-time with 31 and ranks third in regular season coaching wins in the NFL with 302. He is also in second place for combined regular season and postseason wins, and also second place for most regular season coaching wins with one franchise. Belichick is one of only three head coaches who have won six NFL titles. He was named the AP NFL Coach of the Year for the 2003, 2007, and 2010 seasons. Belichick has also been selected to the NFL 2000s All-Decade Team, NFL 2010s All-Decade Team, as well as the NFL 100th Anniversary All-Time Team, and is the only active head coach on the latter team.

Early life and education
Belichick was born in Nashville, Tennessee, on April 16, 1952, the son of Jeannette (née Munn) and Steve Belichick.

Belichick was named after College Football Hall of Fame coach Bill Edwards, who was his godfather. He is of Croatian ancestry; his paternal grandparents, Marija Barković and Ivan Biličić, emigrated from Draganić in 1897 and settled in Monessen, Pennsylvania, having changed their names to Mary and John Belichick at the suggestion of immigration officers.

Belichick was raised in Annapolis, Maryland, where his father was an assistant football coach at the United States Naval Academy. Belichick has said his father is one of his most important football mentors, and Belichick often studied football with him. Bill reportedly learned to break down game films at a young age by watching his father and the Navy staff do their jobs. Belichick graduated from Annapolis High School in 1970, where he was a classmate of Sally Brice-O'Hara, who would later become the Vice Commandant of the Coast Guard. While there, Belichick played football and lacrosse, with the latter being his favorite sport. Belichick enrolled at Phillips Academy in Andover, Massachusetts, for a postgraduate year, with the intention of improving his grades and test scores to be admitted into a quality college. The school honored Belichick 40 years later by inducting him into its Athletics Hall of Honor in 2011.

Belichick attended Wesleyan University in Middletown, Connecticut, where he played center and tight end. In addition to being a member of the football team, Belichick played lacrosse and squash, serving as the captain of the lacrosse team during his senior season. A member of Chi Psi fraternity, Belichick earned a bachelor's degree in economics in 1975. Eventually, he was part of the inaugural induction class into the university's Athletics Hall of Fame in spring 2008.

Early coaching positions
After graduating, Belichick took a $25-per-week job as an assistant to Baltimore Colts head coach Ted Marchibroda in 1975. In 1976, Belichick joined the Detroit Lions as their assistant special teams coach before adding tight ends and wide receivers to his coaching duties in 1977. Belichick was dismissed along with head coach Tommy Hudspeth and the rest of the coaching staff on January 9, 1978. He spent the 1978 season with the Denver Broncos as their assistant special teams coach and defensive assistant while also serving as director of films.

New York Giants (1979–1990)
In 1979, Belichick began a 12-year stint with the New York Giants alongside head coach Ray Perkins as a defensive assistant and special teams coach. Belichick added linebackers coaching to his duties in 1980 and was named defensive coordinator in 1985 under head coach Bill Parcells, who had replaced Perkins in 1983. The Giants won Super Bowl XXI and Super Bowl XXV following the 1986 and 1990 seasons. Belichick's defensive game plan from the New York Giants' 20–19 upset of the Buffalo Bills in Super Bowl XXV has been placed in the Pro Football Hall of Fame.

Cleveland Browns (1991–1995)
From 1991 until 1995, Belichick was the head coach of the Cleveland Browns. During his tenure in Cleveland, Belichick compiled a 36–44 record, leading the team to the playoffs in 1994, his only winning year with the team. Coincidentally, Belichick's lone playoff victory during his Browns tenure was achieved against the New England Patriots, who were coached by former Giants head coach Bill Parcells, in the Wild Card Round during that postseason. In Belichick's final season in Cleveland, the Browns finished 5–11 despite starting 3–1. One of his most controversial moves was cutting quarterback Bernie Kosar midway through the 1993 season. Kosar was signed by the Dallas Cowboys two days later and won a Super Bowl with the Cowboys in Super Bowl XXVIII as a backup. In November 1995, in the middle of the ongoing football season, Browns owner Art Modell had announced he would move his franchise to Baltimore after the season. After first being given assurances that he would coach the new team that would later become the Baltimore Ravens, Belichick was instead fired on February 14, 1996, a week after the shift was officially announced.

New England Patriots (1996)
After his dismissal by the Cleveland Browns, Belichick served under Parcells again as assistant head coach and defensive backs coach with the New England Patriots for the 1996 season. The Patriots finished with an 11–5 record and won the AFC Championship over the Jacksonville Jaguars, but they lost to the Green Bay Packers in Super Bowl XXXI amid rumors of Parcells's impending defection.

New York Jets (1997–1999)
Belichick had two stints as the head coach of the New York Jets without ever coaching a game.

In February 1997, Belichick, who had been an assistant coach under Bill Parcells with the New York Giants and New England Patriots, was named the Jets interim head coach while the Jets and Patriots continued to negotiate compensation to release Parcells from his contract with the Patriots and allow Parcells to coach the Jets. Six days later, the Patriots and Jets reached an agreement that allowed Parcells to coach the Jets, and Belichick became the team's assistant head coach and defensive coordinator.

When Parcells stepped down as head coach after the 1999 season, he had already arranged with team management to have Belichick succeed him. However, Belichick was the Jets' head coach for only one day. On January 4, 2000, when Belichick was introduced as head coach to the media—the day after his hiring was publicized—he turned it into a surprise resignation announcement. Before taking the podium, Belichick scrawled a resignation note on a napkin that read, in its entirety, "I resign as HC of the NYJ." He then delivered a half-hour speech explaining his resignation to the assembled press corps.

Soon after this bizarre turn of events, Belichick was introduced as the Patriots' 12th full-time head coach, succeeding the recently fired Pete Carroll. The Patriots had inquired to the Jets about permission to interview him for their vacant spot at head coach just prior to Parcells stepping down. Parcells and the Jets claimed that Belichick was still under contract to the Jets, and demanded compensation from the Patriots. NFL Commissioner Paul Tagliabue agreed, and the Patriots gave the Jets a first-round draft pick in 2000 in exchange for the right to hire Belichick.

Return to New England (2000–2023)
Soon after hiring Belichick, owner Robert Kraft gave him near-complete control over the team's football operations, making him the de facto general manager as well. Until 2009, Belichick split many of the duties normally held by a general manager on other clubs with player personnel director Scott Pioli, though Belichick had the final say on football matters. Pioli left for the Kansas City Chiefs after the 2008 season.

The Patriots went 5–11 in the 2000 regular season and missed the playoffs.

First three Super Bowl wins: 2001–2004
In 2001, the Patriots went 11–5 in the regular season, and in the playoffs defeated the Oakland Raiders (in the "Tuck Rule Game") and Pittsburgh Steelers on the way to the Super Bowl. In Super Bowl XXXVI, Belichick's defense held the St. Louis Rams' offense, which had averaged 31 points during the season, to 17 points, and the Patriots won on a last-second field goal by Adam Vinatieri. The win was the first Super Bowl championship in Patriots history.

The following season (2002)—the first in Gillette Stadium—the Patriots went 9–7 and missed the playoffs. New England finished with the same record as the New York Jets and the Miami Dolphins, but the Jets won the AFC East title as a result of the third tiebreaker (record among common opponents).

The Patriots' 2003 season started with a 31–0 loss to the Buffalo Bills in Week 1, a few days after they released team defensive captain Lawyer Milloy. However, they dominated through the remainder of the season to finish 14–2, setting a new franchise record for wins in a season. In the final week of the regular season, the Patriots avenged their loss to the Bills by the same 31–0 score. They defeated the Tennessee Titans in the divisional round of the playoffs. Playing against the Indianapolis Colts and Co-MVP Peyton Manning in the AFC Championship Game (Steve McNair of the Titans was also Co-MVP), the Patriots recorded four interceptions, and advanced to Super Bowl XXXVIII, where they defeated the Carolina Panthers 32–29 on a late Adam Vinatieri field goal. Belichick was awarded the NFL Coach of the Year Award.

In 2004, the Patriots once again finished with a 14–2 record, and they defeated the Indianapolis Colts in the divisional round of the playoffs. They opened the season at 6–0, which combined with the 15 straight wins to end the previous season, gave New England 21 consecutive victories to break the record for most wins in a row formerly held by the Miami Dolphins with 18 straight victories in the 1972 and 1973 seasons. They defeated the Pittsburgh Steelers in the AFC Championship Game. In Super Bowl XXXIX, the Patriots beat the Philadelphia Eagles and became only the second team to win three Super Bowls in four years. Belichick is the only coach to accomplish the feat as the Dallas Cowboys had two head coaches in the stretch they won three of four from 1992 to 1995.

Perfect regular season and Brady's injury: 2005–2009
With a new defensive coordinator in Eric Mangini and no named offensive coordinator, the Patriots went 10–6 in the 2005 season and defeated the Jacksonville Jaguars in the Wild Card Round before losing to the Denver Broncos in the Divisional Round. Earlier, with a season-opening win over the Oakland Raiders, Belichick notched his 54th win with the Patriots, passing Mike Holovak as the winningest coach in Patriots history.

The Patriots finished with a 12–4 record in the 2006 season and defeated the New York Jets by a score of 37–16 in the Wild Card Round. They then beat the San Diego Chargers the next week in the Divisional Round, before losing to the eventual Super Bowl XLI champion Indianapolis Colts in the AFC Championship by a score of 38–34. The Patriots led 21–3 midway through the second quarter, but the Colts mounted one of the great comebacks in playoff history.

In 2007, Belichick led the Patriots to the first perfect regular season since the introduction of the 16-game regular season schedule in 1978, only the fourth team to do so in National Football League history after the 1934 and 1942 Chicago Bears and 1972 Miami Dolphins. In the Divisional Round of the playoffs, they defeated the Jacksonville Jaguars by a score of 31–20. In the AFC Championship, the Patriots defeated the San Diego Chargers by a score of 21–12. The Patriots were upset in Super Bowl XLII 17–14 by the New York Giants, his former team, due to the defense allowing a famous play to David Tyree near the end of regulation. The Patriots' failure to attain a "perfect season" (undefeated and untied, including playoffs) preserved the Miami Dolphins as the sole team to do so, having finished their 1972 regular season at 14–0 and having won three games in the playoffs. Only two other teams in professional football have recorded a perfect season—the 1948 Cleveland Browns (14–0) of the then All-America Football Conference and the 1948 Calgary Stampeders (12–0) of the Canadian Football League. No team in the former American Football League ever had a perfect season.

During the Patriots' 2008 season-opener against the Kansas City Chiefs, quarterback Tom Brady sustained a season-ending injury in the first quarter. Backup quarterback Matt Cassel was named the starter for the remainder of the season. However, with a win in Week 2, the Patriots broke their own record for regular season wins in a row with 21 (2006–08). After losing over 12 players to the injured reserve list, including Rodney Harrison, Adalius Thomas, and Laurence Maroney, the Patriots still managed their league-leading eighth consecutive season with a winning record, going 11–5. However, the Patriots, who finished second in the AFC East, missed the playoffs for the first time since 2002, losing on tiebreakers to the Miami Dolphins (who won the division on the fourth tiebreaker, better conference record) and the Baltimore Ravens (who beat out the Patriots for the last playoff spot due to a better conference record). The 1985 Denver Broncos are the only other 11-win team to miss the playoffs in a 16-game season.

In 2009, with a fully healthy Tom Brady back as the starting quarterback, Belichick was able to guide the Patriots to yet another AFC East division title with a 10–6 record. However, the Patriots lost to the Baltimore Ravens in the Wild Card Round.

Spygate
In an incident dubbed "Spygate," on September 9, 2007, NFL security caught a Patriots video assistant taping the New York Jets' defensive signals from the sidelines, which is not an approved location. The NFL rules state: "No video recording devices of any kind are permitted to be in use in the coaches' booth, on the field, or in the locker room during the game." Jets coach Eric Mangini, a former Patriots assistant, tipped off league officials that the Patriots might have been filming their signals. After the game, the Jets formally complained to the league.

On September 13, the NFL fined Belichick $500,000—the largest fine ever imposed on a coach in the league's 87-year history, and fined the Patriots $250,000. Additionally, the Patriots forfeited their first-round draft pick in the 2008 NFL draft. NFL Commissioner Roger Goodell, a former employee of the Jets, said that he fined the Patriots as a team because Belichick exercises so much control over the Patriots' on-field operations that "his actions and decisions are properly attributed to the club." Goodell considered suspending Belichick but decided that taking away draft picks would be more severe in the long run. Gary Myers, a columnist for New York's Daily News columnist, stated Belichick should have been suspended by Goodell for the Patriots' next game against the Jets.

Belichick later issued the following statement:

"I accept full responsibility for the actions that led to tonight's ruling. Once again, I apologize to the Kraft family and every person directly or indirectly associated with the New England Patriots for the embarrassment, distraction and penalty my mistake caused. I also apologize to Patriots fans and would like to thank them for their support during the past few days and throughout my career. [...] As the Commissioner acknowledged, our use of sideline video had no impact on the outcome of last week's game. We have never used sideline video to obtain a competitive advantage while the game was in progress. [...] Part of my job as head coach is to ensure that our football operations are conducted in compliance of the league rules and all accepted interpretations of them. My interpretation of a rule in the Constitution and Bylaws was incorrect. [...] With tonight's resolution, I will not be offering any further comments on this matter. We are moving on with our preparations for Sunday's game."

The sanctions against Belichick were the harshest imposed on a head coach in league history until the New Orleans Saints' Sean Payton was suspended for the entire 2012 season for covering up a scheme in which bounties were paid for deliberately knocking opponents out of games.

Following the incident and its fallout, Belichick led the Patriots to a perfect 16–0 regular season record, and was awarded the 2007 NFL Coach of the Year Award, as voted on by the Associated Press.

Making five Super Bowls and winning three, Gronkowski, and "We're on to Cincinnati": 2010–2019
In the 2010 season, Belichick and the Patriots finished with a 14–2 record for the top seed in the AFC. However, their postseason ended quickly with a 28–21 loss to the New York Jets in the divisional round.

In the 2011 season, the Patriots topped the AFC with a 13–3 record. Following a victory over the Denver Broncos in the divisional round of the playoffs, the Patriots won the AFC Championship game, beating the Baltimore Ravens 23–20 when the Ravens failed to score a touchdown and Baltimore's kicker, Billy Cundiff, missed a routine 32-yard field goal attempt to tie the game and send it into overtime. This sent New England to their fifth Super Bowl under Belichick. In Super Bowl XLVI, the Patriots lost in the Super Bowl XLII rematch to the New York Giants by a score of 21–17.

On September 26, 2012, following a 31–30 loss to the Baltimore Ravens, Belichick was fined $50,000 for grabbing a replacement official's arm while asking for more specific clarity on a ruling after Baltimore had narrowly converted a last-second field goal attempt to secure the win. The Patriots finished the 2012 regular season with a 12–4 record. In the divisional round of the playoffs, they defeated the Houston Texans by a score of 41–28 and made it to the AFC Championship Game, where they lost to the eventual Super Bowl XLVII champion Baltimore Ravens by a score of 28–13, ending their season.

The Patriots began the 2013 season with much upheaval on the offensive side of the ball with the injury of Rob Gronkowski, the arrest and subsequent release of Aaron Hernandez, the departures of Wes Welker to the Denver Broncos and Danny Woodhead to the San Diego Chargers in free agency, and the release of Brandon Lloyd. To replace them, the Patriots signed Danny Amendola in free agency, drafted rookies Aaron Dobson and Josh Boyce, and signed undrafted rookie free agent Kenbrell Thompkins. The team finished the season with a 12–4 record, winning the AFC East and securing a playoff berth and a first-round bye, seeding second in the AFC standings. In the Divisional Round, they defeated the Indianapolis Colts by a score of 43–22. They lost to the Denver Broncos in the AFC Championship Game by a score of 26–16.

In the 2014 season, Belichick's Patriots started 2–2. At a mid-week press conference following a 41–14 loss to the Kansas City Chiefs, Belichick famously uttered, "We're on to Cincinnati" (referring to the Patriots' next opponent), several times in response to follow-up questions and criticisms of his team, Brady in particular. Ultimately, they recorded a 12–4 record for the third straight season. In the Divisional Round, they defeated the Baltimore Ravens by a score of 35–31. During the AFC Championship Game, they defeated the Indianapolis Colts by a score of 45–7. They reached Super Bowl XLIX, where they defeated the Seattle Seahawks by a score of 28–24. With his fourth championship as head coach, Belichick tied Chuck Noll for most Super Bowl wins by a head coach.

In the 2015 season, the Patriots recorded a 12–4 record for the fourth straight season. They defeated the Kansas City Chiefs in the Divisional Round by a score of 27–20. During the AFC Championship Game, the Patriots narrowly lost to the eventual Super Bowl 50 champion Denver Broncos by a score of 20–18.

In the 2016 season, the Patriots recorded a 14–2 record, which earned them the #1 seed for the AFC playoffs. In the Divisional Round, they defeated the Houston Texans by a score of 34–16. During the AFC Championship Game, they defeated the Pittsburgh Steelers by a score of 36–17. They reached Super Bowl LI, where they defeated the Atlanta Falcons in a comeback victory by a score of 34–28 in overtime. The Patriots were down 28–3 at one point in the third quarter. With the victory, Belichick won his record fifth Super Bowl title as a head coach.

In the 2017 season, the Patriots went 13–3, setting an NFL record eighth consecutive 12-or-more-win seasons, capturing their ninth consecutive AFC East title and their 15th of the last 17 seasons. They defeated the Tennessee Titans in the Divisional Round by a score of 35–14 and the Jacksonville Jaguars in the AFC Championship Game by a score of 24–20, claiming their second consecutive AFC title, while also extending their record of consecutive AFC Championship Game appearances with seven. Super Bowl LII was Belichick's eighth title game as head coach and his eleventh overall in any capacity, which was also the Patriots' tenth appearance, all extending NFL records. The Ringer wrote that Belichick's "team is different from many of New England's famous teams from the previous decade: The first iteration of the Patriots dynasty relied on defense. This year, they are 29th in yards allowed (though fifth in points allowed) and instead have perfected the art of situational football." The latter Patriots teams were noted for mounting late comebacks in playoff games. However, the Patriots fell to the Philadelphia Eagles in Super Bowl LII, 41–33, as Eagles quarterback Nick Foles repeated his dominant NFC Championship Game performance and led Philadelphia to victory in a high-scoring game. The Patriots were down early, as they had been in most of their Super Bowl wins. However, they could not make a comeback this time, although they came very close. Eagles defensive end Brandon Graham strip-sacked Tom Brady to get the ball back with about two minutes to go in the fourth quarter. The Patriots did get the ball again before the end of the game, but they ran out of time to score.

In the 2018 season, the Patriots went 11–5, failing to win 12 or more games for the first time since 2009. Despite this, they still captured their 10th consecutive AFC East title and their 16th of the last 18 years. They defeated the Los Angeles Chargers in the Divisional Round by a score of 41–28 and the Kansas City Chiefs during the AFC Championship Game 37–31 in a tough overtime game in Kansas City to advance to their third straight Super Bowl. In Super Bowl LIII, the Patriots defeated the Los Angeles Rams 13–3 to give Belichick his sixth Super Bowl championship as a head coach and his eighth overall to have the most Super Bowl rings in NFL history. His six championships matched both George Halas and Curly Lambeau for most championships as a head coach. The Patriots' defense held the high-scoring Rams offense to only 260 total yards.

On May 13, 2019, Belichick announced that he would assume another role as the Patriots' defensive coordinator starting the 2019 season. On October 27, 2019, with the Patriots' win over the Cleveland Browns, Belichick obtained his 300th win, regular and postseason combined, as a head coach. The Patriots finished the 2019 regular season with a 12–4 record, winning their 11th consecutive AFC East title. However, the Patriots were defeated in the Wild Card Round of the playoffs by the Tennessee Titans, led by former Patriots linebacker Mike Vrabel, by a score of 20–13.

Brady goes to Tampa Bay, Cam Newton, Mac Jones, and final years in New England: 2020–2023
Following the departure of Tom Brady to the Tampa Bay Buccaneers, Belichick and the Patriots were faced with an uncertain quarterback situation for the first time in nearly two decades. During the offseason, the Patriots signed former Carolina Panthers starter Cam Newton for the 2020 NFL season. The off-season routines and schedules, as well as the normal processes of regular season were severely disrupted by the worldwide COVID-19 pandemic. Despite the unanticipated difficulties and challenges of the pandemic, the Patriots were in the hunt for a playoff spot until late in the season, ultimately finishing 7–9. The 2020 season was Belichick's first losing season since his first year in New England.

In the 2021 NFL draft, the Patriots selected quarterback Mac Jones with the 15th overall pick. After Jones and Newton competed for the starting job during the preseason, Belichick made the decision to release Newton and name Jones the starter for the upcoming season. During Week 4, Brady's Tampa Bay Buccaneers visited the Patriots in his first trip to Gillette Stadium since signing with the Buccaneers. A missed 56-yard field goal by Patriots kicker Nick Folk allowed Tampa Bay to narrowly escape with a 19–17 victory. Immediately after the game, Brady and Belichick shared a quick embrace on the field before Brady greeted his former teammates and other members of the Patriots organization. Though fans criticized Belichick for his lack of warmth displayed towards his former quarterback, the two privately spoke at length in the Buccaneers locker room following the match. Belichick helped lead the Patriots to a 10–7 record in 2021. The team fell to the Buffalo Bills in the Wild Card Round by a score of 47–17.

In the 2022 season, despite starting quarterback Mac Jones being injured in Week 3 and subsequently missing three more weeks, the Patriots remained in the hunt for a playoff spot until the last week, finishing with a record of 8–9.

During Week 4 of the 2023 season, the Patriots lost to the Dallas Cowboys by a score of 38–3. In doing so, Belichick suffered the worst loss of his coaching career (35 points). The following week, the Patriots lost to the Saints by a score of 34–0, giving Belichick his worst home loss of his career. Two weeks later, New England upset the Buffalo Bills 29–25 to earn Belichick his 300th career regular season win as an NFL head coach. After a Week 10 10–6 loss to the Indianapolis Colts in Germany and subsequent bye week, Belichick named Bailey Zappe the team's starting quarterback. In Belichick's final game with New England, the Patriots lost to the New York Jets 17–3, snapping the team's 15-game winning streak over the Jets. The Patriots finished the season with a 4–13 record, the team's worst in Belichick's 24 seasons as head coach.

On January 11, 2024, Belichick and the Patriots mutually agreed to part ways. On January 15, Belichick was interviewed by the Atlanta Falcons for their head coaching position, but ultimately did not get the job as the Falcons hired Raheem Morris instead.

Overall record in New England
Under Belichick, the Patriots had a regular-season record of 266–121–0 over 24 seasons. Belichick is the most successful coach in Patriots history; his 266 wins with the franchise are more than quadruple those of runner-up Mike Holovak. Belichick also compiled a 30–12 record in the playoffs with New England, including a 6–3 record in Super Bowls. He led the Patriots to 17 divisional titles, including five consecutive titles from 2003 to 2007 and eleven consecutive titles from 2009 to 2019. This streak of 11 consecutive playoff appearances is the most in NFL history for any team.

Media career
While still serving as head coach for the Patriots in 2019, Belichick appeared as one of three main analysts, alongside host Rich Eisen and Cris Collinsworth, for the NFL 100 All-Time Team series on NFL Network, serving as a voter, in addition to providing his analysis of each member's significance and breaking down tape of highlight plays. Belichick was chosen in these roles due to his exceptional knowledge of American football, to the extent that he and fellow former head coach John Madden were specifically assigned to look over film of the earliest players selected to the team. Belichick was awarded a Sports Emmy in 2021 for his contributions to the series.

After mutually parting ways with the Patriots in 2024, Belichick, while still declaring himself an active head coach, officially agreed to appear every Monday afternoon during the 2024 NFL season with ESPN's The Pat McAfee Show, first appearing as an analyst on the show during its "5th Annual Draft Spectacular", covering the 2024 NFL draft, following a guest appearance weeks prior.

Peyton Manning revealed during the Netflix special The Roast of Tom Brady that Belichick would join another ESPN program, joining the Manning brothers (Peyton and Eli) in the Manningcast, an alternate live television broadcast of Monday Night Football. A week afterward, Manning stated during an appearance on The Pat McAfee Show that Belichick would appear on every Manningcast broadcast during the 2024 season.

During the offseason, Belichick visits other football programs to learn from their experiences. For example, he has studied the Navy run offense, sought Bill Walsh (in past years) to understand more about the San Francisco 49ers as an organization and the West Coast offense as a system, and spent time with Jimmy Johnson to learn about drafting and contract negotiations.

The track record of Belichick's coaching tree has been characterized as poor. Former assistant coaches under Belichick had a combined 208–296–1 (.410) record as head coaches of their own teams through November 28, 2020, and a number of them ended their brief tenures as head coaches by being fired midseason. As of the end of the 2020 season, the only members of this coaching tree to have career NFL head coaching records above .500 were former coaches Groh (9–7) and O'Brien (52–48 during season, 2–4 in playoffs).

Personal life
Nick Saban and Belichick are good friends. In 2007, when Belichick spoke about their relationship, he said: "Two successful Croats in the same division of NFL. You must admit, you don't see that every day." In May 2018, President Donald Trump appointed Belichick to be a member of his Council on Sports, Fitness & Nutrition.

In June 2024 it was reported that Belichick was in a relationship with Jordon Hudson, who is a 24-year-old former cheerleader.

Belichick has an Alaskan Klee Kai dog named Nike. Interest in the breed surged after Nike made an appearance on camera during the 2020 NFL draft.

Belichick has dual Croatian/American citizenship. He received Croatian citizenship on June 3, 2024, in Banski dvori in Zagreb from the Croatian prime minister Andrej Plenković. He was also special guest of the association football friendly match on Stadion Rujevica between Croatia and North Macedonia.

Family
Belichick was married to Debby Clarke from 1977 to 2006. They have three children. Daughter Amanda played lacrosse at Wesleyan University. She is the head women's lacrosse coach at the College of the Holy Cross in Massachusetts in July 2015. Son Stephen played lacrosse and football at Rutgers University and was an assistant coach with the Patriots. Son Brian is an assistant coach with the Patriots.

Starting in 2007, Belichick was in a relationship with Linda Holliday, the executive director of the Bill Belichick Foundation. The relationship ended in 2023.

Declined Presidential Medal of Freedom
On January 10, 2021, Politico reported then-President Donald Trump planned to award Belichick the Presidential Medal of Freedom. Belichick indicated that he was flattered to be considered for the honor, but declined the award in a statement issued the next day. His statement referenced the January 6 United States Capitol attack, which the House of Representatives had accused Trump of provoking when it impeached for the second time of his presidency, and cited Belichick's "great reverence for our nation's values, freedom and democracy" in light of that event. A number of Massachusetts politicians, including Senator Ed Markey and Representative Jim McGovern, had previously called on him to decline after news of the award became public.
