Duran for sure, then probably Julio Cesar Chavez, then Leonard, then probably Mike Tyson and George Foreman or Tommy Hearns.
As much as I hate to pick someone other than Roberto, I have to go with Roy Jones Jr His very long prime was more dominant than any living boxer. He was fast and he was powerful.
A collective view of this forum from 2020 has it: 1) Duran 2) SRL 3) RJJ 4) Pacquiao 5) Mayweather Jnr 6) Whitaker 7) Hearns 8) Hagler 9) JCC 10) Holmes I have a slightly different order to my top 9 (same top 2 though) and I'd have Michael Spinks ahead of Larry Holmes, but otherwise I think the right names are there for the greatest top 10 living boxers p4p: This content is protected
Based on my own personal rankings, which are derived from work done in said division alone: HW - Holmes LHW - Spinks MW - Hopkins WW - SRL LW - Duran FW - Lopez BW - Olivares Fly - Canto
