Personally, until someone puts him on his ass, I think people should lay off the big man. He's KO'd or beaten everyone that's been put in front of him, and as many people suggest, he's got fair hands and heavy punches, and I also think he'd beat Sam Peter if he was put in front of him.
When we reach the creme de la crme of the current generation of heavyweights, and it's not exactly very cramy at the moment, I think it would be very competitive between Valuev and Toney or Rahman, but i'm with everyone else who wants to see Valuev v Wlad K.

and it would be a top notch fight too.
