well I don't think so. Mugabi was expected to fall early and Hagler believed it. And Hagler always wanted that big fight with Hearns and got it, and his motivation seemed to wane a little after that fight. He had a nose injury in sparring training for Mugabi,, and the fight was postponed from November 1985, to MArch 1986. And Marvin came in a little less toned than with Hearns. I just think he lost a little motivation after Hearns. He put his all out with Hearns and I think he satisfied something. With Mugabi then he had another fight where he was hit hard and by the time Leonard fought Marvin another year after Mugabi, I think Marvin was a shell. I could be wrong. Marvin retired at the right time.
