Since this topic just turned into a comparison of ALi and Jones and mythical match ups between the 2. There is no comparison in my opinion. ALi fought everyone that was good or great in his era at any place. Can Roy Jones say that? Of course not, that's why from time to time on boxing forums there are Roy Jones VS. Nigel Benn, Chris Eubanks, Gerald McClellan threads or the if Roy was in his prime against a prime Joe Calzaghe who would win?

Ali fought any good/great HW in his era. There aren't any of those hypothetical questions with how he would fare with Foreman, Shavers, Norton, Frazier, Liston, etc. And here's another thing, even when he was a young champion he still fought contenders in their own hometown/country like the English fighters such as Brian London, Henry Cooper, etc.
