Lists of all-time greats in boxing are a dime a dozen. That being said, I rate Floyd as an ATG. However, I'd definitely rate (in no particular order) SRR, SRL, Ali, Duran, JCC, Gomez, and Hagler over him right off the top of my head. It's foreseeable he falls out of my Top Ten if I gave it enough thought. Just outside Top Ten is by definition still an ATG.
