The Habs was going after Krejci, a valued Boston skill player with no fighting mettle at all. Going after a skill player with Chara on the ice gets you turned into a blue, blanc et rouge paste. Komi was handy and a guy Chara could legitimately take it out on. It's really that simple.
Come onnnnn. You can't honestly believe that. Imagine some Boston players were roughing up one of our skilled players in the corner after the whistle and then Laraque just jumps in there and starts beating the hell out of a guy like Ward. Tell me you wouldn't mind that. It was a cowardly act on Chara's part and completely against the player's code.
