They earned 54 wins and 121 points, surpassing the previous records set by the 1968–69 Montreal Canadiens.
The NHL's top four scorers (Phil Esposito, Bobby Orr, Johnny Bucyk, and Ken Hodge), each with over 100 points, were all Bruins; previously, there had only been four players in the history of the NHL with 100-point seasons, and no other NHL franchise has ever produced the top four scorers in a season (the Bruins replicated the feat in 1973–74).
With 76 goals and 152 points, Esposito broke Bobby Hull's single season record for goals, as well as his own single season points record, both set in 1968–69.
However, the team's unprecedented offence was shut down by rookie goaltender Ken Dryden, who guided the Montreal Canadiens to a seven-game upset against the Bruins in the first round of the playoffs.
The postseason ended quickly for the Bruins as they lost in the opening round to the Montreal Canadiens and their rookie goaltender Ken Dryden in a seven-game upset.
