I think I'd go with Sanders. He blitzed Wald, and had Vitali in bad trouble early. I think he smokes Mr. Can't Fight A Lick before the big oaf lands his right.
Corrie would demolish him. Wilder doesn't have a shot. Corrie was a great counter puncher against very skilled boxers. You're telling me he's not gonna counter in between wilder's windmill punches? Corrie ko5. Wilder throws 4 punches in total in the first 4 rounds.
Sanders easily. He's too aggressive and fast and Wilder wouldn't know what to do to evade the left hand. Simply backing up looking for a counter right wouldn't work, he'd have to actually parry/slip/block/clinch, all skills he doesn't have.
