based on what exactly? Its very very difficult to hit a man bobbing so low when your 6'8 and your style is to be completely bolt upright. Foreman was horrible for Joe because of the type of punches he threw. Joe gave Ali hell for 44 rounds, because he was so hard to hit clean, and threw huge punches at a high workrate in return. Vitali is better than Wlad, but I still cant see anything other than Frazier winning over the distance.
Frazier stops him late. No doubt in my mind. He would make Wlad lose his bearings and drown him. Vitali has a MUCH better chance. A prime Frazier is all wrong for Wlad IMO.
