Re: Wladimir Klitschko vs. Rocky Marciano
Rocky wouldn't even be a heavyweight today.
He'd start off as a big lhw or a small cw. Maybe over time he could bulk up but any advantages he might have had he'd surely lose. Tiny frame and in reality this fight would never be sanctioned.
If he came boring in to get inside he'd get sparked out. If he tries staying on the outside he gets dominated behind the jab. He has very little chance of victory considering his size and reach.
