I'm too young to have a real opinion on those guys, Boida, but at least they were heavyweights.
duran was not a big guy. he never fought above middlewight.
jones doesn't even warrant a response.
Frazier was fighting for the heavyweight crown at 205 pounds or so...
I'm not sure exactly what it is about Roy Jones Jr that you think doesn't "even warrant a response" as you so cleverly put it.
Maybe you should say nothing to your knowledge
that would warrant a response. He made the same mistake common to a lot of prizefighters - staying in the game far past his prime. But in his professional career he won titles in the middleweight, super middleweight, light heavyweight and heavyweight divisions. He is the ONLY fighter in history to start his career as a junior middleweight, and win a title as a heavyweight.
At the very, VERY least warranting a response in a discussion about the best boxers of all times.
