I think Povetkin's bigger problem against Wlad will be lack of reach and defence. Losing some fat and adding muscle won't fix that.
Wlads resume is far superior to Povetkins. Povetkin gets hit with right hands constantly. He has not real power. His knockouts were against bums and a way past his prime Bryd. Wlad is a nightmare for Povetkin. Than add the height, Speed, and power difference.
Even if he can, there's a slew of HWs out there now, big strong mofos. Haye won't make it, I can't see it.
That's the point. They both gave Haye trouble even though they are smaller than Povetkin and don't hit as hard. As far as I know, Povetkin has never been knocked down in the amature or pro ranks. That could change, but his chin definitely seems solid. Could be a very bad style matchup for Haye.
