Lewis I don't think has that great of a jaw. He had to hold onto Tyson like his life depended on it for the first 4 or 5 rounds. Great champion overall, but imho, he doesn't have heart that I've seen in others.
George Foreman was not better than Moorer when he won... but he was alot smarter. Absolutely amazing he was able to keep his wits after that kind of beating, get Moorer into position, and then lay him out. He wasn't that smart when he fought Ali. Had he not left boxing when he did, he could very easily be a contender for the greatest.
Tyson was a rampaging beast in his prime, but he could never go the distance. He gets frustrated too easily and loses focus. He doesn't fight smart either. I watched him duck into the same Lewis uppercut probably 100 times.
Ali, Liston, Louis, Jefferies, Johnson, Tunney, Holmes... I dunno. If I had to pick, I'd go with Ali since he was pretty entertaining, but they're all on the same level imho.
Now, if we want to compare greatest pound for pound fighters of all time, that's easy, Sugar Ray Robinson.. unless you go back to bareknuckle & bring up Fitzsimmons & Dempsey.
