I wouldn't even say that Lewis was more "powerful" than Ali or had a better jab. Ali had a nice, quick, and effective jab. Lewis does have a nice, stiff jab, but he could barely beat Klitchko. Still, a lot of people fail to realize that Lewis only won 40 fights before he retired. I don't know if I could even say that Lewis could have beaten Joe Frazier, Ken Norton, George Foreman, or others like this. He's just not as good as Ali.
