He was on real bad legs in the 8th, 9th rounds, how was he going to run? I was suprised he made it through the 10th round. All of a sudden he was going to find spring in his legs and start dancing?. His legs were shaky that whole fight; count up the times he missed and fell. Watch the rest of his career and see his legs.
And he didn't know how to fight that way, it just wasn't in his nature.
