That would require Wlad to come within punching range. Wlad would hold him while Vitali does the actual hitting.
Louis KO'd Buddy Baer and Primo Carnera who are similar in size to Wlad but had better chins. Louis was too accurate,fast combos and strong. Bitchko loses in 6.
They are not the same ****ing fighter. Edit: if you meant a handicap match, or a tag team match, then the Klitschkos.
