Prime Tyson or Tyson who unified the different Championship belts has too much defensive skills on offense and is too aggressive and heavy-handed for Wladimir. Against Vitali, it's more a question of hard pace imposed throughout and Vitali fighting on survival mode just like Tucker. What this means is that neither Wlad or Vitaly could punch on light feet at a tremendous pace like Buster Douglas did in Tokyo or hang on and absorb to fire right back like Vander did in 96. However I think that either Klitschko could have KTFO the Tyson version who fought Lennox.
Klittard logic Chris Byrd = Jimmy Young Derek Chisora = Joe Frazier Sam Peters = Mike Tyson Leapai = Tua As for the thread in question. Tyson beats Vitali pillar to post. Wladmir could last the distance (because of excessive hugging of which he is an undisputed expert) but would lose a wide UD. If Wladmir engages, he gets KTFO
And Tyson fought many fights that lasted more than 6 rounds and won, what is your point? Stylistically Wlad would be beaten rather badly by a prime Mike Tyson within 4 rounds, the same way he beat Larry Holmes and Holmes is a superior fighter to Wlad.
