I think he destroys them all, and beats Vitali clearly in a tough fight as well. Yes Vitali could probably take his punch, but the same is very true in reverse, and Tyson would have a MUCH easier time landing and doing effective work inside imo. When has Vitali actually fought well enough to suggest he would win more rounds than Tyson at his absolute peak, I'm having a hard time seeing this. Vitali is tough as nails, but he is fairly clumsy and upright, and he wouldn't have the ability to keep Tyson at bay. I think if you gave Wlad his brothers chin, that probably spells doom for Tyson, but Vitali doesn't have nearly as good a jab or right hand, and couldn't keep the distance as well.
