Wilder would not beat Vitali. Any other boxer in history of heavy weights I think he has a chance beating by finding the place for the most devastating right hand in history of boxing because of the speed and eye and fearness of situation to just launch that punch with everything behind it. He goes for it all in when he launches it. Vitali vas a defense minded man with super human reflexes to avoid the punch and he would jab wilders face into red tomato. And he was similar size as Wilder. Wilder would have no chance to beat Vitali. He would not be a favorite against many of all time greats, but he has a chance against anybody not named Vitali. Mike Tyson maybe stylishly and chin-wise another one that is close to unbeateable. Anyone else, Lewis, Foreman etc. etc. probably would be favourites, but suspect to potential KO to happen. He is anything from 1 - 30 H2H like any top talent in the division is and has been.
If you're reffering to Wlad, then beating any of Povetkin, Haye, Mercer and Pulev is much more impressive than beating Ortiz, Breazeale , Duhaupas Stiverne and Arreola.
Don't forget Ibragimov, Chageav and Byrd. I just can't respect Klitschko tho. No other HW champion in history would let them get pushed off a boat by Shannon Briggs
Maybe the question should be which of those on your spreadsheet would Wilder be capable of beating as well?
