Someone wanted me to post a comprehensive list of ATG rankings of Pac and May with Pac ahead:
https://bleacherreport.com/articles...st-pound-for-pound-boxers-of-all-time#slide74
Some criteria that were used:
"Their skill and accomplishments relative to others in their division(s).
2. Their ability to win in multiple weight classes, if applicable.
Do you favor wins and losses? World championships? Quality of opposition? Or maybe it's longevity, or mainstream appeal? It's a measure of a fighter at his peak and how he compared to and fared against the other great fighters of his era."
Pac's accomplishments far outweigh Mayweather's, and he won titles in 8 different weight classes compared to Floyd's 5. Pac even has more wins than Mayweather, superior quality of opposition, longevity, mainstream appeal, and a far more impressive prime/peak than Mayweather. Of almost ALL metrics used, Pac >>>>> Mayweather. Literally, the only thing May has on Pac is he "beat" Pac while May was using IV (likely PEDs) with Pac no longer in his prime with a torn rotator cuff and with Pac 10 lbs above his optimal weight class.
Fact of the matter is that Floyd never fought a HOF or ATG in their primes, and he should've lost to Castillo, while Pac was robbed twice against Bradley and Horn (all-time worst robberies). There are a lot of boxers who have gone more than 50-0, but no one has come close to titles in 8 weight classes. THAT is why Pac is top 5 ATG in my book. Floyd maaaaybe top 20.
It's not as simple as "hurrrr duuurrrr Floyd beat Pac so he's betterrrr". If that were the case, Hearns, Hagler, and SRL would be ranked above Duran. But Duran is top 10 ATG while H/H are in the 30s and SRL is 10-15.
