1973–74 Philadelphia Flyers season

The 1973–74 Philadelphia Flyers season was the Flyers' seventh season in the National Hockey League (NHL). The Flyers became the first expansion team to win the Stanley Cup. Prior to this season, no post-1967 expansion team had either beaten an Original Six team in a playoff round or won a Stanley Cup Final game.

Goaltender Bernie Parent, an "Original Flyer", returned to the franchise in the off-season, and the Flyers proved that the expansion teams could challenge the Original Six in 1973–74. The Bullies continued their rough-and-tumble ways, led by Dave Schultz's 348 penalty minutes, and reached the top of the West Division with a record of 50–16–12. The return of Parent proved to be of great benefit as he established himself as one of if not the best goaltender in the league by winning 47 games, a record which stood for 33 years. Since the Flyers, along with Chicago, allowed the fewest goals in the league, Parent also shared the Vezina Trophy with Chicago's Tony Esposito.

Come playoff time, the Flyers swept the Atlanta Flames in four games in the first round. In the semifinals, the Flyers faced the New York Rangers. The series, which saw the home team win every game, went seven games. The Flyers had home-ice advantage as they advanced to the Stanley Cup Finals by winning Game 7. Their opponent, Bobby Orr and the Boston Bruins, took Game 1 in Boston, but Bobby Clarke scored an overtime goal in Game 2 to even the series. The Flyers won Games 3 and 4 at home to take a 3–1 series lead, but Boston won Game 5 to stave off elimination. That set the stage for Game 6 at the Spectrum. The Flyers picked up the lead early when Rick MacLeish scored a first-period goal. Late in the game, Orr hauled down Clarke on a breakaway, a penalty which assured the Flyers of victory. Time expired as the Flyers brought the Stanley Cup to Philadelphia for the first time. Parent, having shut out Boston in Game 6, won the Conn Smythe Trophy as the Playoff MVP.
