David Haye must use his speed "and dance" according to Lewis. “If he uses his speed he can dance around Valuev. I actually thought Holyfield beat Valuev and he's going to have trouble catching up to David. But if Valuev puts his weight on him, it's a lot to have to push off. David will be trying to hit these guys and knock them out, but these guys don't move easily." Pretty much echoes what most people are saying really. Personally I don't think Holyfield beat Valuev though, they were both as unimpressive as each other.
He fought Donald and I think Donald won that fight. He was robbed. Acually that Donald fight would be the blueprint for Haye, just Haye fights NOTHING like Donald. Completely different style, Haye is much more offensive, taking bigger risks and trying to land bombs from all angles. More exciting, but also exposing his chin more.
I know it was a close fight, but Valuev looks a bit better there than he has done recently. Donald does manage to get inside to land at times though, which is perhaps a good sign for Haye (as you say though, Donald is a different fighter). http://www.youtube.com/watch?v=5cKoHYWZUMU&feature=related
