Has to beat JDS and defend against cain and sum1 else.
Beating the greatest doesnt make you the greatest. Unless u beat a couple lol. If he beats cain but gets whooped by jds and then hunt, his record wont look better than fedor or cain or jds. But definitely top 5-10 heavyweights of all time if he beats Cain.
Nog, fedor, cain, overeem are all amazing wins compared to any heavyweights record if he can accomplish it
