If anything Vitali who has never really gotten beat, had a better shot at beating George. Lets not forget the eras in which these two fighters come from. Wladimir and his brother have ruled a rather weak heavy weight division, big George is an all time great, and he fought and beat some all time greats, Wladimir not so much. I think Frazier would have probably Ko'd Wlademir and we all know what Foreman did to him.
