Stevens used to use his shoulder pads as weapons against skulls.
One time, I think it was late in a game against Carolina, with the outcome already settled, Stevens concussed a player for no reason whatsover, other than to be a prick.
I agree that it's good to be feared, but not because someone is trying to end your career and longterm health.
Going back in time once again, Bobby Clarke was the dirtiest forward I ever saw. He would try and injure you and then hide behind a wall of players.
When the first tournament happened between Russia and Canada, a guy named Kharlamov was a magician on ice for Russia. He wasn't Gretzky, but he was as close as anyone else in ability. Clarke took a two-handed swing at Kharlamov's ankle and broke it, knocking him out of the series. From that point on, I rooted for Russia.
Kharlamov played against North American teams 102 times. He scored 55 goals and added 74 assists, for a total of 129 points.
