1974–75 NHL season

The 1974–75 NHL season was the 58th season of the National Hockey League. Two new teams, the Washington Capitals and Kansas City Scouts, were added, increasing the number of teams to 18. To accommodate the new teams, the NHL re-organized its divisional structure and playoff format. The regular season was expanded to 80 games per team (which would be the case until 1992–93). The Philadelphia Flyers won the Stanley Cup for the second consecutive year.

League business
With the addition of two new teams, the Washington Capitals and Kansas City Scouts, the NHL bumped up the number of games from 78 to 80 and split the previously two-division league into two conferences with four divisions. Because the new conferences and divisions had little to do with North American geography, geographical references were removed until 1993–94. The East Division became the Prince of Wales Conference and consisted of the Adams Division and Norris Division. The West Division became the Clarence Campbell Conference and consisted of the Patrick Division and Smythe Division. The Capitals had the worst season ever recorded in the history of major professional hockey, and the third worst in the postwar era the following season, while the Scouts the following season will have the fifth worst record of the postwar era.

The Clarence S. Campbell Bowl and Prince of Wales Trophy (previously awarded to the first-place finishers of the West Division and East Division respectively) are now awarded to the first-place finishers of the Campbell Conference and the Wales Conference respectively.

Cancelled relocation
In early 1975, newspapers reported that the California Golden Seals and Pittsburgh Penguins were to be relocated to Denver and Seattle respectively, in an arrangement that would have seen the two teams sold to groups in those cities that had already been awarded "conditional" franchises for the 1976–77 season. After staunchly rejecting previous franchise relocation attempts, league president Clarence Campbell saw this as a method by which the NHL might extricate itself from two problem markets, while honoring the expansion commitments it had made. The Penguins ended up staying in Pittsburgh (and ultimately, over time, made Pittsburgh one of the NHL's stronger markets), while the Golden Seals moved to Cleveland in 1976 to become the Cleveland Barons before merging with the Minnesota North Stars in 1978. The Scouts gave up on Kansas City after two seasons and moved to Denver to become the Colorado Rockies in 1976 before moving east to East Rutherford, New Jersey in 1982 and becoming the New Jersey Devils; Denver returned to the NHL in 1995 when the Quebec Nordiques moved there and became the Colorado Avalanche, where they remain to this day. Seattle was later awarded an expansion team, the Seattle Kraken, in 2018 that began play in 2021.

Regular season
For the first time ever in the National Hockey League, there was a three-way tie for first place overall. The respective divisional leaders of the Norris (Montreal Canadiens), Patrick (Philadelphia Flyers), and Adams (Buffalo Sabres) all had 113 points. By virtue of having the most wins, the Flyers were accorded the league's best record and held home-ice advantage in the playoffs, where they eventually met the Sabres in the Stanley Cup Finals.

The Vancouver Canucks, which had been playing in the original East Division since they debuted in the league, were moved over to the Campbell Conference and led the way in the Smythe Division with a meager 86 points.

Bobby Orr won the scoring title for the second time, the only defenceman in the history of the NHL to accomplish this feat.

The surprise team of the year were the Los Angeles Kings. The Kings, with their disciplined defensive style, and excellent goaltending tandem of Rogie Vachon and Gary Edwards, battled Montreal all year for first place. The Kings opened their season by beating the defending champion Philadelphia Flyers in Philadelphia and tying the Canadiens in Montreal. The Kings lost only twice in their first 26 games, and on Christmas, Montreal had only a two-point lead in the standings. When L.A. won in Montreal in mid-January, they were back in first place. The teams continued to battle, with the Canadiens finally clinching first place with three games to play.

Playoffs
With the new conference and division structure, the 1975 playoffs used a new format. The playoffs were expanded from eight to twelve teams with the top three teams in each division qualifying for the playoffs. The first place teams in each division earned a first round bye, while the second and third place teams were seeded 1–8 based on their regular season record and played a best-of-three series. The four preliminary series winners joined the four division winners in the quarterfinals, and they were again re-seeded 1–8 based on regular season record. The teams that advanced to the semifinals were reseeded 1–4. Proponents of this re-seeding state that it makes the regular season more important by rewarding teams with better records with potentially easier matchups. In addition, it avoids the potential issue of two lower seeded teams (who may have pulled early round upsets) playing each other in the next round while two higher seeded teams are playing each other (as is possible in a "bracketed" playoff format like in the NBA). The biggest beneficiary of this format was the Vancouver Canucks, who were ninth overall in the regular season but received a first-round bye for winning the relatively weak Smythe Division. Unfortunately for Vancouver, the fact that the Quarterfinals was re-seeded regardless to their first place divisional finish meant they had to face another division champion in the second round, the Norris-winning Montreal Canadiens, who defeated Vancouver 4–1. The team that suffered the most from the new format, the Los Angeles Kings, had the fourth best overall record but had to play in the risky mini series where they were upset by the twelfth-seeded Toronto Maple Leafs 2–1.

(2) Buffalo Sabres vs. (7) Chicago Black Hawks

(3) Montreal Canadiens vs. (6) Vancouver Canucks

The Vancouver Canucks entered the playoffs as the Smythe Division champions and the sixth seed in the quarterfinals as the third lowest remaining seed in the playoffs, earning 86 points during the regular season. This was the first playoff series between these two teams. Montreal swept all four games in this year's regular season series.

(4) Pittsburgh Penguins vs. (5) New York Islanders
The Pittsburgh Penguins entered the Quarterfinals as the fourth seed and they qualified for this round by defeating the St. Louis Blues in the preliminary round.

(1) Philadelphia Flyers vs. (4) New York Islanders
This was the first playoff series between these two teams. The Flyers won this year's season series earning eight of twelve points during the regular season. After becoming the second North American professional sports team to win a best-of-seven series after trailing 3–0 in the previous round against the Penguins, the Islanders almost accomplished the same feat in this round. However, the Flyers firmly defeated them in game seven to preserve the series win. In doing so, the Islanders set a record for most consecutive playoff wins when facing elimination, 8. This would mark the last time an NHL team forced a seventh game of a best-of-seven series after trailing 3–0 until the Flyers themselves did so against Boston in the 2010 Eastern Conference Semifinals.

(2) Buffalo Sabres vs. (3) Montreal Canadiens
This was the second playoff series between these two teams, with Montreal winning the only previous meeting in six games in the 1973 Stanley Cup Quarterfinals. Buffalo won this year's season series earning nine of ten points during the regular season.

Broadcasting
Hockey Night in Canada on CBC Television televised Saturday night regular season games and Stanley Cup playoff games. HNIC also produced Wednesday night regular season game telecasts for CTV.

This was the third and final season under the U.S. rights agreement with NBC, airing weekend afternoon regular season games and playoff games. This would be the last season until the 1990s that NHL games would air on American network television. Unable to sign a U.S. national television contract for the 1975–76 season, the league put together a broadcast syndication package called the NHL Network to have games aired on various independent stations.
