Povetkin. Im not denying Deontay carries the weapons to stop him ofcourse and theres a fait chance that happens but ive watched alot of Wilders fights and they all have a decent portion of success against him, Povetkin would be the best technical fighter he has faced yet so if he has any success before Wilder gets the chance to KO him he could finish it 1st. And because all Wilders past opposition has had some success before being knocked out i give the edge to Povetkin. And yes i know hes old, hes alot younger than Ortiz and he was only 1 more clean shot off finishing Wilder.
