Jus because he dunt knock one guy out, dunt mean he has no power. Tyson didnt knock everyone out. This whole power punchin thing is a bit of a joke in fact. Look at Miguel Cotto for example. U would say he has a lot of power.........but then you could argue, wel he should have because he enters the ring about 15 pounds heavier then his opponent. Same with Ricky hatton. We saw what happened when hatton only had a 2 pound advantage over collazo. Hell Cotto couldn't put malignaggi away with a near 20 pound advantage. Does he also have no power then?
