I'd pick Wilder in this one. For all the shit Wilder gets about his windmilling (which is deserved), his most potent weapon - the straight right, is actually really to the point and well excecuted. I genuinely think, as shit a boxer as he is, if he lands that properly on any heavyweight in history, nobody is "shaking that shit off" bar somebody with a titanium chin like McCall.
Bump Morrison could actually approach this fight like he did against Foreman and box for 12 rounds. Now whether or not he can make Wilder look like the mudshoe Trinidad is the question
