Sure he is good at fighting.
That is it.
Is he the reason we lose games? No. Is he the reason we win games? No.
He's in the lineup to make sure things don't get out of hand, but when the other team doesn't dress a heavy weight like Dallas, then what is his purpose? To be "physically intimidating"? Sorry, but with the instigator penalty other teams would want him to jump them as all they have to do is "turtle" and then they would have a nice power play.
All in all, do I think he's fun to watch fight? Hell yeah, but I don't think we need to get carried away with thinking anything more.
