Wilder tends to freeze up when confronted by a good boxer with decent defense. Klitschko is extremely economical with his punches, not throwing unless he can land while being safe. Wilder won't get many opportunities to land a counter on anything Klitschko throws. Wilder also isn't the kind of fight to press the action unless he completely outmatches his opponent. The fight would be fought at Klitschkos pace. Something you can't let happen if you want to beat Klitschko.
Both Wlad and Vitali would spark him out cold now, let alone prime, near prime, or past prime versions of them. Donkeypotamus is garbage.
Wlad has a decent pair of whiskers, and has amazing recovery ability. He showed that against Joshua and Samuel Peter.
Before 2013 it would be a 50/50 fight, but after Wlad gets knocked out badly. Wlad started slipping a lot around the Povetkin fight. By 2015 when Wilder won the WBC title and was the only other champion Wlad knew better than to pursue the Wilder fight.
Wlad would destroy that fraud. Like others have said, within 5 or 6 rounds,Wilder takes his canvas nap.
Wilder has had 9 years to fight Wlad. AJ has taken over the division from Wlad because Wilder never stepped up.
Wladimir starts the beginning of Wilders end with a stiff jab... then finishes him off the that nuclear 1-2 right down the pipe. It wouldn’t even have to land on the button either.
