I think being an amateur for so long ruined him....he had 209 wins and 12 losses. That's a lot of fights for a guy who went pro at age 24....had he started out earlier and then gone pro at 20 or something that would have been different but in the amateurs he more than likely tried to use his size advantage to win fights and he fell in love with his power and well you just have to be really special to rely on your power that much....he needed to be able to box more and being a pro earlier would have helped him out.
