He is pretty tough and he has size like you said but he takes a lot of really dumb penalties. I would say he is a 4th liner but how many 4th liners get traded that many times in one season?
I agree, that is pretty damn weird. Especially because its not like the guy really has any potential to be better then a 4th liner. I guess he's other team's Donald Brashear. They consider him dead space and just continue to dump him for anything they can get.
