6. Ulf Samuelsson
It's one thing to call a hockey player an enforcer, but Samuelsson took it to a whole new level...dude ended careers. Such was the case with this hit on Cam Neely and a high stick that hit the eye of Pierre Mondou. His controversial style of play earned him 2,453 career penalty minutes. They didn't call him "Tough Ulf" for nothin'.
