I don't buy that...he's actually a reasonably talented hockey player. Without acting like a douchebag he'd still be effective, he can skate, he can score an occasional goal, but most of all, if he plays the system that his team utilizes, he's a solid, if unspectacular, forward.
Some opponents and teammates have said as much...that he's a good player who chooses to spend his time on the ice antagonizing...it's effective, but he'd be equally effective, in other ways, just playing hockey.
On the other hand, despite the Rangers record with him last year, his teammates wanted him gone, as did his Dallas teammates, and I suspect other teammates wherever he's played. He's a fkn embarrassment and when you're own teammates have no respect for you, that, IMO, offsets any short term gains.
