Julio Cesar Chavez. From 1984 to 1990 he had it all and demonstrated it all. It just came too easy, too naturally to him. And he was so incredibly dominant. He did not fade until years later when weight gain, partying, shop wear and idolatry got the better of him.
I always enjoy seeing Jones Junior get recognition. We were privalliged to see him. Once in every generation? I don't think so.
How can you tell what is raw talent & what is learned technique ?... only the fighters themselves would know that.... all I can do is judge a fighter on film & Pep & Whitaker were the best on pure boxing ability for me.
Ali at his best was one of the absolute best outside boxers in history, very few fighters got inside on him, his lateral movement, jab, combinations & reflexes were the best of all time p4p, why else do you think no other fighter above 200 lbs has ever came close to replicating him. I`d say Ali was a better boxer than Jones, Jones was great though, not knocking him at all.
