You mean how would he do against Chambers, Rahman, Byrd, Donald, Bostice and Mahone? He'd probably beat a lot of them.
Chambers, unlikely. Rahman, probably wins, though not as one sidedly. That version was shot as well. Byrd, first and second iterations both beat Povetkin. Donald, probably wins, though not a walk in the park. Chagaev, loses.
No, he would easily beat Lennox Lewis too. He destroyed Rahman who KO'd Lewis. Therefore, Povetkin>>>>>>>Lewis
It's not like I pulled all of those specific names out of my ass. :blurp Oh, he knows what he's doing. Champion is a known quantity, here. A smooth criminal, if you will.
