Vitali would go down as every other opponent does. Tyson's style fits perfectly with Klitschko's. He was made to destroy taller opponents. I don't even doubt in the slighest Tyson would beat Vitali. I would think a KO but I'm not quite sure. Tyson is a beast... Vitali couldn't take mike's power punches, look he quit with Chris Byrd. He would need to be TOUGH to stand up to Tyson. But even if Vitali could keep coming, Tyson's defense is rock solid. I doubt he could do anything. By the way, this is the young tyson right? The old one... I'd bet my money on Vitali... maybe.
