Even the greatest fighter of all time (don't ask me who it is) would have someone against he would lose more so than win.
Well, english is my second language, but I'm not really interested in word play. The point is Vitali is no an ATG and saying he "could" beat any heavyweight is a pretty far fetched speculation. What do you base your statement on genius?
I'm a big Toney fan. He's surely an all time great. But believe me, he can't win a round against Vitali. The size difference is just too big and Vitali's reach will kill him. A fight between a 6'8 beast and a 5'9 former middleweight is not a fair fight. No shame in that.
