Haye is too short to be effective vs Vitaly, Haye could try to outsmart Wlad, get inside and unload but he failed. Vitaly is slower but he knows how to keep opponent at the distance with his jab, size and leaning out defensive style. Even if Haye get close he will have to catch Vitaly with a clean shot because Vitaly's chin is kind of granite. Haye is very secure himself so probably the fight will be similar to Valuev's with larger percentage of punches absorbed by Haye. I see Haye being able to stun Vitaly once or twice during the fight.
