I dont think so. Marvin Hagler may well be the best Middleweight of all time. You can make a case that he should have been undefeated if not for the politics in boxing. And he has that unbelievable chin. He was relentless. Amazing. Have you seen 'The War'? Against Tommy 'Hitman' Hearns. Again Im a big Roy Jones Jr. fan but I highly doubt if he could be in the shoes of Hearns. And Hearns was a phenomenal puncher too. Hagler by late round TKO.
