I firmly believe that Holland wants all 23 players to be the best hockey players he can ice. If some of them also fight it's a bonus, but he won't remove a PKer or supplementary scorer to throw a guy out there who's only talent is giving the other team the stink eye and throwing his fists around. Know what I mean? That's why this Callahan kid makes me happy- he seems like he might be just that kind of "hockey player who also fights" guy.
How would you explain Kopecky, then? He wasted roster space from more important players in GR. He was certainly not one of the 23 best at anything on the team.
Also, hopefully this Callahan is tougher than "Dirty Harry" Callahan.
According to my profile, my reputation is excellent. LOL.
