I will say this once again.Ali NEVER fought someone like Wladimir or Lewis and viceversa so there is no reasonable argument one way or the other.Everthing is different from back then including the glove size which would make a big difference in KO% if todays heavyweights were still wearing the lighter gloves.Logic would say that a guy like Lewis, with his skill, size, and power would overwhelm Ali but logic doesn't always prove to be fact.Ali fought a couple of big guys but they were not on the same skill level as Wladimir or Lewis, they were in an era of smaller heavyweights which helped them to win as many fights as they did.If Lewis had fought in that era his record would have been even better, same with Wladimir.This is of course all speculation based off of all the fights I have seen of Ali's,Lewis's and Wladimir's.Nobody can say with certaintly like some are that Ali would easily beat these guys unless they actually fought.Anyone who says otherwise is just full of it.
