Yeah Povetkin's listed at 6-2, which is quite "shrimpy" next to behemoths Wilder (6-7) and Fury (6-9). If Wilder worked feverishly on his boxing skills and using his jab like you alluded to, he very well might keep Povetkin honest enough to go into the late rounds and win either by late KO or decision. But I think Wilder's spectacular KO victories against lesser opponents have not given him the incentive to think he may have to hone his skills. Dangerous against someone like Povetkin.
