It was the first game in NHL playoff history in which a team down by three goals in the third period came back to win the game and hence the series. The Boston Bruins defeated the Toronto Maple Leafs in seven games in the 2018 Stanley Cup playoffs. It was the first time the B's had won a series after being down 3-0. The Maple Leafs were leading 3-0 after two periods of play, but then scored four straight goals to take control of the game. Boston responded with four of their own before Toronto finished off the game with another goal just over five minutes into overtime. This is how the series went: Game 1 Toronto wins 4-3; Game 2 Toronto wins 5-4 (OT); Game 3 Boston wins 6-5 (SO); Game 4 Boston wins 7-6 (SO); Game 5 Toronto wins in OT 4-3; Game 6 Toronto wins in SO 3-1 (beating the clock); Game 7 Toronto wins in SO 3-0. This series was unique because it wasn't decided until game seven in overtime. In fact, this series lasted longer than any other 7th game in NHL history. The previous longest series was also in game seven of a seventh game series - it took nine games to decide the 1968 Montreal Canadiens vs New York Rangers series.
