1975 Stanley Cup playoffs

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.

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 division winners then joined the four preliminary series winners in the quarterfinals, and they were again re-seeded 1–8 based on regular season record. This re-seeding took place again in the semifinals, with the teams seeded 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 seeded without regard 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 four games to one. 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 two games to one.
