The Elias Sports Bureau provided us with this perspective:
The Bruins are the first team in NHL history to win a Game 7 after trailing by three goals in the third period.
Patrice Bergeron is the first player to score the tying goal with less than a minute in regulation and the game-winning goal either in regulation or overtime in Game 7 of a playoff series.
Also of note:
• This was the Bruins fourth overtime win in a Game 7, tied with the Detroit Red Wings for the most all-time..
• The Bruins are the only team this season to score two goals in a game with an extra attacker on the ice in place of a pulled goalie. They did so in the regular season (coincidentally against their next opponent, the New York Rangers) and in this Game 7.
• This was Bergeron’s second career overtime playoff goal. He also scored one in the 2003-04 postseason. It also was only his second multi-goal game of the season (he had one March 14 against the Florida Panthers).
• Bergeron recorded a point on the Bruins' last three goals in Game 7. He was on ice for only three of the Bruins' first 19 goals in the series, recording one point.
• The Bruins scored six goals in that round on shots from the point against Maple Leafs goalie James Reimer, including the game-tying goal in the third period. Reimer’s six goals allowed from the point were twice as many as any goaltender this postseason.
• Tuukka Rask earned only his second win in nine postseason games in which his team had a chance to eliminate an opponent.
• The Bruins know how rough it can be to blow a 3-0 lead in a Game 7. They blew both a 3-0 lead in games and in score in Game 7 of their playoff series against the Philadelphia Flyers in 2010.
Lastly, for just how rare a comeback this was, we go back to Elias:
The last time a team won a postseason game when trailing by three or more goals with 11 minutes or fewer left in the third period was April 18, 2001, when the Los Angeles Kings rallied from a 3-0 deficit to beat the Red Wings, 4-3 in overtime.
And the last time a team won a postseason game when trailing by two or more goals with two or fewer minutes left in the third period was April 18, 1993, when the Quebec Nordiques rallied from 2-0 down with 89 seconds remaining to beat the Montreal Canadiens, 3-2 in overtime.
