I havent seen many calzaghe fights but the few I've seen, he has huge stamina and just punches and punches, I think it might be tuff for pav against him, not saying Pav couldnt win, but hed face a guy bigger, probably stronger , just as skilled, more experienced and who has just as much heart as pav does. I'd pull for pavlik and hope he would whip calzags arse cause hes my fellow american
