He's been like this almost all the time. He nearly got stopped by Hopkins in the first fight and in general he seizes up late on. He's fast-twitch athlete and that doesn't lend itself to long fights. It's all genetic. He always makes 'statements' with his one-twos, you always notice them. They seem to take alot of energy away from him. His whole body gets involved. He can't throw 'fluff' - can't throw arm punches to buy time or pick up points. It's either the big statement-making one-two combinations or nothing. He needs to find a cruising level, an in-between gear.
He's slow on his feet. Its is biggest flaw. He's just not mobile enough and as a result he has a tendency to stand flat footed at critical times. When Froch would bull rush him he displayed terrible lateral movement. If he had just got on his horse for the last round he would have won but he just couldn't do it.
Stamina ..Thats the main problem ..He over extends him self in fights ..What he does in the first rd he needs to reserve that energy for the 12th ..
