I believe Duran was out of shape and undisciplined and unfocussed for much of the 1980s, he liked to party and his performances suffered. He's human after all. It's no excuse for losing though, it's no valid alibi. In fact, his quitting and his losing to some of those ordinary fighters impacts on his greatness, IMO, especially his quitting against Leonard. He would forfeit any consideration I might have to place him among the very best p4p ATGs with that stunt alone. Not that I'd necessarily place him that high without it.
