Top 10 ATG Floyd 'Money' Mayweather: What would have to be done from for it to be?

That is hard to say. I think he does need to put on a great run at 154. He can't do it beating any one at 147 and below. Maybe 1 or 2 catchweight fight vs 160 champs also.

I really don't make ATG lists any more but if push comes to shove I have him top 30, maybe top 25 in a good day. A lot of incredible performances but never had his signature win vs a future HoF, let alone vs an ATG. Fight with ODLH, Castillo and Corales are awesome but not quite the same caliber of victory you expect from a top 10 ATG like Ali, Duran, SRR, and SRL had. Hagler has Duran and Mugabi and that is far better wins than any of PBF's wins. And Hagler is not top 10 ATG (at least by most boxing followers. Though he is in my top 5 fav of all time.).

 

Genaro*, Manfredy, Corrales*, C.Hernandez, J. Chavez, Castillo X2*, Gatti, Judah, Baldomir*, Oscar, Hatton, JMM, Mosley*, Ortiz, Cotto*

*=has some claim as having beaten the best guy in the division

That is a solid top tier opponents, considering that only four of these fights were even remotely competitive is the most impressive. The manner in which he disposed of his opponents, virtually shutting them down and winning every round convincingly, boosts his resume more than if he had the same opponents fought with a bunch being close fights, some wars, and a couple defeats. Would he have been more entertaining and fan friendly with that? Yes. Better? Absolutely not. I've always valued the 0 much more than others when ranking/speaking of Lopez and Marciano, so Floyd would be no different there. It's actually amazing that Calzaghe and Floyd have managed to create a generation of fans who specifically attack undefeated fighters with baseless claims.
