IMO if you fought 12 guys who are all ATG's and thats all you fought, and you beat them all or had a winning record, then IMO you deserve to be near the top.

IMO competition and consistency are the two most important things to define greatness, who can fight the biggest variety and the highest caliber of opposition and still come out on TOP

that is why IMO a guy like Leonard or Duran should be way higher than JCC in the ATG list because they fought and beat better guys even though they fought less guys, and in Duran's case he did much better later on in his career than JCC did.
