He only looked good against guys he was ridiculously bigger than, since he's moved up from 135 he hasn't impressed me one bit, even bum of the month Carlos Molina more than held his own against him FFS.
He is not as good as people say he is. He looks like a beast fighting smaller guys that can't hurt him. Step up with guys his weight and it's a different story.
Because he has speed, power, athleticism and accuracy. But his technical abilities are fairly limited.
:rofl Khan would make Broner look silly,the other guys you mentioned would beat him as well,not sure about Berto.
