Re: ATG's who could never beat a Prime ATG @their fighting weights?
ATG who never beat another ATG at there respective weight class?
Hate to say it but Marvin Hagler comes to mind. He beat Hearns, Duran, lost a close and questionable decision to Leonard, beat Vito and some other good fighters but the best he beat (Hearns and Hagler) moved up to MW.
Now, could Hagler have defeated some other ATG MWs? I say definately!
