He made a clean hit, was grabbed and challenged. He didn't back down and promptly kicked his ass. If you're going to be an "in your face" hockey team, that's how I expect them to play.

If Dorsett is going to play on the 2nd line, he can't spend 4-10 minutes of each game in the box. He's gonna have to decline a few fights. It's as simple as that.
