Maple Leaf Moment

An instance where a sports team has an almost unbeatable lead, yet blows that lead and loses in an immense comeback by the opponent. Referencing the 1st round of the Stanley Cup playoffs in 2013, game 7, when the Toronto Maple Leafs blew a 4-1 lead with 11 minutes left in the game to the Boston Bruins, eventually losing the game in overtime.
