i pick wladimir to beat Larry Holmes. I am not sure at all that he would beat wilder. Deontay has a hell of right hand and he is a very good finisher, taking in count the guys that did hurt Holmes badly then wilder definitely would hurt him too and could finish him while he is losing on the cards, i am not sure, Holmes was better sure but sometimes it is not enough
Perhaps a prime Wladimir would beat Holmes (I doubt it though) certainly not a 40+ Wladimir. I give Wilder almost no chance of beating Holmes barring a lucky punch.
