As far as "jumping" is concerned, the Carolina crew put it more eloquently -- Harrison put Chara in a position where he had no choice but to fight. That took Chara off the ice for the ensuing PP, on which the Canes scored, got the crowd into the game and raised the blood pressure on both benches. Carolina goes on to win their first home game in 8 tries.
Perfect example of a fight affecting the outcome of a game. The Hurricanes players were giving Harrison props in postgame interviews for stepping in against a guy well outside his class, and risking an epic beatdown, for the sake of the team.
