Well, since Chisora thinks that, guess it's settled. We can forget all about Vitali getting pulled in the 6th due to his face being destroyed.
Chisora is baiscly right, Lewis was very fortunate that night he was thorurghly out boxed. If Lewis wanted to prove he was the better boxer he should have rematched Vitali.
if you are letting your oponents reach your face, regardless of whether its their thumb or knuckles, then you are failing defensively. Vitali lost because he failed to defend himself. He may have boxed well, but he didnt box in the way necessary to beat Lennox, in that his defence failed him.
Lennox at his worst, beat Klitschko. Lennox at his best would have finished Klitschko at the top level. Remember the Lennox who showed up to settle it with Hasim Rahman? That's a scary proposition for Vitali, who got mauled by an unmotivated Lennox, who was not in great shape. Imagine how much quicker, and how much more stamina he would have had if he shed off 8 pounds, and trained properly for this fight.
