Often. He killed penalties, blocked shots, and would goad the other team into taking penalties by taking a fist without retaliating. Unfortunately the power play is so bad they didn't take advantage of it. And how does him getting suspended hurt the team? They don't pay the fine. I'd rather have 50 games from Kaleta than 80 games from some of the floaters on this team.
The message to the kids on the team is that you're better off playing soft and going through the motions like Stafford, Leino (who is now the highest paid forward), and Myers, than sacrificing your body and playing with passion like Kaleta.
