Sanders had stamina for 3 rounds only. He would probably drop Povetkin early, but later would gas and get KOed.
I like both these guys. I think Sanders brings more physicality and athletic attributes to the table, in terms of size, reach, explosiveness etc. Povetkin seems to me to be the more consistent performer with better infighting skills. Honestly I could see either one beating the other. Best for best, H2H, I think Sanders is too quick and powerful for Povetkin. I do however think that Sasha will be closer to his best for more of his career than Sanders, and resume wise, I feel he is a greater fighter than Sanders, the Wlad win notwithstanding.
