whyte will win but late on, technique and boxing brain belongs to povetkin, whyte usually out toughs people, strong, but never looks skillful. povetkin will prolly school whyte for the first half of the fight, might even score a knockdown, but older man will get outlasted in the end.
Pov is old but is still a tough cookie . Only Joshua has stopped him. He is also one of the best technicians at HW. If Whyte shows up in best shape then his size and youth will wear Pov down to a conclusive UD. If Whyte show up with the belly and man bumps that he had against Wach i think Pov could very well ko him mid rounds.
