Does the Walcott who was robbed of a victory over Louis outdo Henry Cooper's performance against a young Ali?
He would outdo Cooper and he would have more a chancde at landing the knockout blow than Cooper did when he nearly knocked Ali out, Ali wasn`t prepared for his fight wityh Cooper and was a lot faster, fitter and better in the rematch, Ali in `63 gets beat by Walcott from `47.
I think he'd go through hell, but I think Ali's toughness speed etc. would see him grind out a win late.
Ali could definitely lose this , Walcotts experience tells a tale . But I can see Ali also come from behind to stop him .
