Hagler could never replicate that performance. Hearns had more upside in a second fight. Hagler could'nt adjust. If Hagler came with the same hand speed from the Mugabi or Leonard fight then Hearns eats him alive. People judge Hagler off that one fight. As a boxer Hagler would'nt have a chance against Hearns. If he chose to box Hearns- Hagler gets knocked out or stoped on cuts. If he pressured Hearns- Hearns would hold him and not "exchange with Hagler" thus wearing down. Also I'm convinced theres a good chance Hearns hurts Hagler in a second fight. Not from a brawl but from long range. Hagler earned the first fight. But Tommy was the better fighter. Also Hagler was not the same fighter after the Hearns fight. Tommy was still in his prime.
