2020 Stanley Cup playoffs

The 2020 Stanley Cup playoffs was the playoff tournament of the National Hockey League (NHL) for the 2019–20 season. The playoffs began on August 1, 2020, and concluded on September 28, 2020, with the Tampa Bay Lightning winning their second Stanley Cup in franchise history, defeating the Dallas Stars four games to two in the Stanley Cup Finals. The playoffs were originally scheduled to begin in April, a few days after the regular season, and end in June. However, on March 12, the regular season was suspended due to the COVID-19 pandemic.

On May 26, commissioner Gary Bettman confirmed that the league was going to use a 24-team playoff format to finish the season, conducted in two or more host cities as "hubs" with players placed under strict health protocols, quarantined from the general public, and all games played behind closed doors with no fans admitted. On July 10, the league ratified an agreement for its protocols with the NHL Players Association (NHLPA). The Eastern Conference played its early-round games at Scotiabank Arena in Toronto, while the early rounds for the Western Conference, as well as the conference finals and Stanley Cup Finals, were played at Rogers Place in Edmonton. This was the first Stanley Cup playoffs to be contested entirely in Canada since 1925, as well as the first time that the Stanley Cup was awarded on Canadian ice since 2011.

The Boston Bruins made the playoffs as the Presidents' Trophy winners with the most points (i.e. best record) during the regular season. The Pittsburgh Penguins increased their postseason appearance streak to fourteen seasons, the longest active streak. For the first time since 1996, all California-based teams, the Anaheim Ducks, Los Angeles Kings, and San Jose Sharks, missed the playoffs. Six Canadian-based teams made the postseason this year, the most since 1993. It also marked the first time since 1986 that all four teams in cities based in Western Canada made the playoffs. In addition, it marked the only time to date that both the Winnipeg Jets and Arizona Coyotes (previously the original Jets, before relocation) qualified for the playoffs in the same season, as well as the only time that the Coyotes made the playoffs since 2012. This was the last playoff appearance for the Coyotes before suspending operations four years later. For the first time since 1999, all former World Hockey Association teams (Edmonton Oilers, Arizona Coyotes, Carolina Hurricanes, and Colorado Avalanche) made the playoffs.

Game two of the second round series between the Vancouver Canucks and Vegas Golden Knights was the 94th game of the 2020 Stanley Cup playoffs, surpassing the previous single-year record of 93 established in 2014. On September 17, the Tampa Bay Lightning became the first team in NHL history to win the clinching game of their first three series in overtime. The Dallas Stars set the record for the most games played in one playoff year (27) in game six of the Stanley Cup Finals; the previous record (26) was shared by the 1987 Philadelphia Flyers, 2004 Calgary Flames, 2014 Los Angeles Kings, 2015 Tampa Bay Lightning and 2019 St. Louis Blues. Game six of the Stanley Cup Finals was also the 130th game of the playoffs, setting the all-time record for most games played in one playoff year.

All games that were originally scheduled on August 27 and 28 were postponed due to a wildcat strike, in response to the shooting of Jacob Blake in Kenosha, Wisconsin.

Playoff format
On May 26, the league announced that 24 teams (12 per conference) advanced to this special conference-based playoff tournament with teams being seeded based on their points percentage at the time the regular season was suspended on March 12. The top four teams in each conference played in a separate seeding round-robin, with regular season overtime and shootout rules, with the clubs accumulating points like the regular season, to determine the seeding in the first round. In addition, any ties in the Round-robin standings were broken by the regular season points percentage. The eight lower seeded teams in each conference played in the Qualifying Round, a best-of-five series with playoff overtime rules. The winners of these series advanced to face one of the Round-Robin teams in the First Round.

On May 28, the NHL stated that both the Round-robin and the Qualifying Round were to be counted under playoff records, on the same day that the league declared the winners of the stats-based regular-season NHL awards. The league then announced on June 4 that all series after the Qualifying Round would remain a best-of-seven series but were re-seeded after each round. With the ratification of an extension to the collective bargaining agreement on July 10, the league also announced that all teams participating in the qualifying round are considered to have made the playoffs and have participated in a playoff series.

Host cities
The playoffs were held in two "hub" cities both in Canada; Edmonton, Alberta at Rogers Place, and Toronto, Ontario at Scotiabank Arena. They were announced as host cities on July 10 with the NHLPA's ratification of the Return to Play plan, and an extension to its collective bargaining agreement with the NHLPA through the 2025–26 season. From the start of the playoffs through to the end of the Second Round, each city hosted all of the games for one conference: the Eastern Conference teams played in Toronto, and the Western Conference teams played in Edmonton. All games in the conference finals and Stanley Cup Finals were played in Edmonton.

Edmonton and Toronto were among a shortlist of ten host cities announced on May 26, along with Chicago, Columbus, Dallas, Las Vegas, Los Angeles, Pittsburgh, Saint Paul, and Vancouver. After the league cut the shortlist down to six cities on June 22, Las Vegas and Vancouver were considered to be the frontrunners to host games. Shortly after this, Vancouver dropped out of consideration on June 25, after health officials in British Columbia were unable to agree with the league on a protocol in the event that a player tested positive for COVID-19. Las Vegas and the other U.S. cities were passed over after Nevada and other U.S. states began to experience a spike in COVID-19 cases in late June; it was reported that the NHL originally intended to have one host city in Canada and one in the United States.

With the New York Rangers playing designated home games in the hub cities instead of in Madison Square Garden, the team's home arena was able to keep its tax exemptions by executing an act of God clause in its agreement with New York City. Under normal circumstances, like the 2014 NHL Stadium Series and 2018 NHL Winter Classic games played at other New York City venues, the Rangers would have always been designated as the visiting team to avoid breaking Madison Square Garden's tax-exempt status.

Each group of teams played inside what was called a "bubble". A secure perimeter was constructed around both venues with various amenities, with Edmonton's covering four hotels in the Ice District and Rogers Place's existing practice facilities, and Toronto's split between Exhibition Place (Hotel X, BMO Field, & Coca-Cola Coliseum) and the Fairmont Royal York hotel (which is connected to Scotiabank Arena). Both sites included fitness, dining and recreation areas. Restaurants were operating within the secure zones, and players were able to order outside food via concierge and local food delivery services. The games were held behind closed doors, but non-participating players were allowed to watch games. A large "stage" with multiple video screens was constructed to cover the empty stands for both teams in each end of the arena, and in-arena presentation was customized for each team when they were the designated home team (including use of their goal music, among other features). The league implemented a compressed playoff schedule with more back-to-back games than usual to help address "bubble fatigue" among the players, who had to live with monotonous daily routines away from their families for several weeks.

Although the general public was not permitted within the direct vicinity of the arena or inside, Oilers Entertainment Group announced plans to set up an outdoor "FanFest" at the site of a former casino near Rogers Place with approval of municipal and provincial health officials, including a "drive-in" screening games and a beer garden.

Medical protocols
Under the Return to Play plan that was ratified on July 10, any player could opt out of the restart without providing a reason and without any penalty, provided that they had informed their team by July 13, when formal training camps opened. COVID-19 tests were then to be administered to players and staff every other day. On July 19, testing increased to three times 48 hours apart. The identities of those who tested positive were not released to the public, they would then be isolated and designated with the generic description "unfit for play" until they were medically cleared, and all injury updates were handled by the league instead of the teams.

Teams arrived at their hub city on July 26; they were isolated in a "secure zone" consisting of their hotels, restaurants, practice facilities, and the arena. Testing was done every day, as well as daily temperature and symptom checks. Individuals had to wear masks outside their hotel rooms except when eating, exercising, or while on the ice or bench. Other exceptions included during interviews with appropriate social distancing.

Under the Quarantine Act, all travellers entering Canada at the time were required to self-isolate for 14 days on arrival. The NHL received an exception to this policy for its players and staff, as long as they remained within the secure zone and were restricted from access to or by the general public. Anybody who left the bubble without prior approval could have faced a mandatory 14-day quarantine or been barred from returning. Teams could have also faced fines or loss of draft picks.

During the conclusions of each Qualifying Round series, teams exchanged fist bumps instead of the traditional handshakes. As players and coaches continued to test negative for COVID-19, the traditional handshake lines returned at the end of each first-round series. After entering the bubble, the league had no personnel test positive for the virus during the playoffs.

 * Qualifying Round

Playoff bracket
In each round, the highest remaining seed in each conference is matched against the lowest remaining seed. The higher-seeded team is awarded home ice advantage. In the Stanley Cup Finals, home ice was determined based on regular season points percentage. Each best-of-five series followed a 2–2–1 format: the higher-seeded team was the designated as the host for games one and two (and game five, if necessary), and the lower-seeded team was the host for games three (and game four, if necessary). Each best-of-seven series followed a 2–2–1–1–1 format: the higher-seeded team was the host for games one and two (and games five and seven, if necessary), and the lower-seeded team was the host for games three and four (and game six, if necessary). In the First Round, the top four teams in each conference were seeded one through four based on their final standings from the Round-robin. The teams that advanced from the Qualifying Round were re-seeded five through eight based on their regular season points percentage.

Exhibition games
Prior to the start of the playoffs, all 24 qualified teams played one exhibition game.

Stanley Cup qualifiers
The top four playoff teams in each conference played in a round-robin tournament against each other to determine the final playoff seeding. The round-robin games were played with regular season overtime and shootout rules, with the teams accumulating points like the regular season, and any ties in the round-robin standings were broken by the regular-season points percentage instead of regulation wins.

The bottom eight playoff teams in each conference played in a best-of-five series to determine which four teams advanced to the first round. The qualifying round games were played with Stanley Cup playoff overtime rules. Seeding was determined by regular season points percentage.

Eastern Conference seeding round-robin
During the first game of round-robin play, the Flyers' Carter Hart made 34 saves against the Bruins in a 4–1 victory.

This would later become the team's final playoff appearance during the Arizona Coyotes' current existence, as by the end of the 2023–24 NHL season, the Coyotes would be considered a suspended operations team, with many of the franchise's assets (but not the team name itself) going to what's considered a newly formed Utah Hockey Club.

Goaltenders
This is a combined table of the top five goaltenders based on goals against average and the top five goaltenders based on save percentage, with at least 420 minutes played. The table is sorted by GAA, and the criteria for inclusion are bolded.

Activism
On August 26, 2020, various professional athletes in the U.S began to go on strike from their respective sports contests in response to the August 23 police shooting of Jacob Blake in Kenosha, Wisconsin, and the protests which followed. These strikes began with the Milwaukee Bucks of the National Basketball Association (NBA). Other players in the NBA, Major League Baseball, Major League Soccer and Women's National Basketball Association soon followed suit and also decided not to play their August 26 games.

When these cancellations south of the border began, NHL players were still isolated in the Edmonton and Toronto bubbles, with game two of the Islanders–Flyers series already in progress when the Bucks first announced their decision to not play. The NHL then continued to play the remaining August 26 games, as NHL players did not take a strong stand for the rest of the day. After pressure brought by the postponement of games by the other leagues, and discussions by players of the Hockey Diversity Alliance such as Evander Kane and Mathew Dumba, the NHLPA announced that they would not play their games on August 27 and August 28. The affected games involved all eight teams remaining: game three between the Flyers and Islanders, game three between the Golden Knights and Canucks, game four between the Lightning and Bruins, and game four between the Avalanche and Stars. The NHL fully supported their decision to postpone the games. On September 1, Dallas Stars president Brad Alberts reported that his team had lost some corporate and personal season ticket holders as a result of the protest.

Media
This marked the sixth postseason under Rogers Media's 12-year contract for Canadian television rights to the NHL. All games were exclusively broadcast by Sportsnet and CBC under the Hockey Night in Canada brand, and streamed on Sportsnet Now, CBCSports.ca (for games televised by CBC), or the subscription service Rogers NHL Live.

This also marked the ninth postseason under NBC Sports' current 10-year contract for American rights. All national coverage of games were aired on either NBCSN, the NBC broadcast network, CNBC, NHL Network, or USA Network. During the round-robins, qualifying round, and first round, excluding games exclusively broadcast on NBC, the regional rightsholders of each participating U.S. team produced local telecasts of their respective games.

Only technical staff such as cameramen and producers were present inside the "bubble". A clean host feed was then sent to media partners to add commentary and surrounding coverage, and interviews with players had to be conducted via videoconferencing. Commentators called the games remotely off of monitors from either their respective studios or from their home arena press boxes. This same arrangement was also done for the radio networks of every team.

While it was initially stated that all commentators would broadcast remotely, the league eventually allowed a handful of both Sportsnet and NBC commentators and reporters into the hubs to call select games. Chris Cuthbert, who jumped from TSN to Sportsnet during the break in June, and Louie DeBrusk were on-site in Edmonton; and Jim Hughson and Craig Simpson were on-site in Toronto during the qualifying, first, and second rounds; they later moved to the Edmonton hub. For NBC, John Forslund, Mike Milbury, and Brian Boucher were initially sent to Toronto; and Pierre McGuire to Edmonton. Milbury was later removed from commentary for the remainder of NBC Sports' coverage after making insensitive comments following the fifth game of the Islanders–Capitals first round series. Gord Miller later joined Forslund, Milbury, and Boucher at the Toronto bubble and alternated with Forslund on a handful of broadcasts. Most of NBC's other commentators began working games remotely from NBC Sports' studios in Stamford, Connecticut, with NBC planning for "the majority of calls" to eventually be conducted on-site, including the last two rounds of the playoffs in Edmonton. Kenny Albert, who worked for both NBC and the New York Rangers radio broadcasts, traveled to the Edmonton bubble after the Rangers were eliminated in the qualifying round. Albert called play-by-play of every game of the Western Conference second round and the first three games of the Western Conference finals before leaving the Edmonton bubble to join the NFL on Fox broadcast team. Forslund, Boucher, and Eddie Olczyk later flew to the Edmonton bubble to call the conference finals. In the case of NBC lead play-by-play commentator Mike "Doc" Emrick, he was working games from his home studio in Metro Detroit because he is a cancer survivor over the age of 70, and therefore at increased risk of severe illness from COVID-19.

Additional cameras were used to provide new angles not usually possible when a crowd is present, and de-emphasize views of the arenas' stands. The telecasts used simulated crowd noise provided by Electronic Arts, combined with recordings of team-specific chants by season ticketholders of participating teams (the latter of which will also be played in-arena). All games carried a five second broadcast delay in order to censor offensive language.

NBC staff were working on the Toronto broadcasts, while Sportsnet staff did the same with the Edmonton broadcasts. Steve Simmons of the Toronto Sun reported that Canadian freelance broadcast workers were upset that NBC personnel were being allowed into Canada to work in Toronto instead of them. The NHL's EVP of communications Gary Meagher stated that splitting production in this manner had been intended "from the onset". Premier of Ontario Doug Ford admitted that plans of NBC's involvement were not part of the early negotiations with the league.

Viewership
Average U.S. viewership of the playoff rounds were down by 28% compared to 2019, the lowest to-date over the course of NBC's current broadcast rights contract. Amid expanded competition due to the difference in scheduling, game one of the Stanley Cup Finals was seen by only 2.12 million viewers; with an average of 2.15 million across the entire series, it was the least-watched Stanley Cup Finals since 2007, and down 61% over 2019. Airing opposite a Monday Night Football contest between the Kansas City Chiefs and Baltimore Ravens, Game six was seen by 2.88 million viewers, the least-watched series-clinching game since at least 2000.
