I think we can all agree that Fury is never going to win any contests in aesthetics or pure athleticism. But he is a fighter and in boxing that can take you a long way.
He might look more of a perfect physical specimen if he took steroids like other fighters do. Bpxing isn't a body building contest. Vitali might have looked in better shape but just look at the Chisora fights for comparison. Tyson toyed with Chisora.
Vitali would still school Fury. He fought a prime Chisora with one arm and dominated him. He would KO early the Chisora who fought Fury. This shot version of Chisora would be schooled by Audley Harrison as well.
Fury beat the best version of Chisora. The Chisora who had just dusted Johnson a lot easier than Vitali. Chisora roughed up Vitali so bad, he had to make an injury excuse to save face.
