Light heavy is 175, cruiser is 200, you must mean weighing 185 in a cruiser fight or catchweight? Eitherway, haye is 225lb in the ring and has to kill himself to make 200, he's really a natural heavy, i think enzo has similar trouble getting down to 200, and is way over come fight time. I think their just too big. Toney is different, he's clearly used steroids and has grown older and got bigger, calzaghe and b-hop have stayed around the same weight for most of their careers, I think joe has always faught at 168, I think its too late for them to go up.
