Well Ice all depends i think Sugar Ray leonard beat the better people and moved up in weight alot more as well so i think he should be higher. Hearns has moved from WW to CW and still knocked people out and beat good people along the way as well. As for Duran he only started losing alot because he was fighting MW Pernell never moved up like Duran did. So i would have to say pound for pound Duran, Leonard and Hearns in my book well always be above Pernell but thats just my thoughts. You say Pernell is up there i say Duran, Leonard and Hearns are above just thoughts that are not wrong or right i guess you could say.
