Why do people think he has a better chance of beating Vitali?

Haye's biggest shot is his power. Vitali has never been stopped and uses his size in a way to barely get hit on the chin. Wladimer has been stopped and his chin is not too hard to find he just holds all the darn time. If you want to talk about Haye stopping someone because he beats neither by decision, then Wladimer would be the choice.
