I see Mayweather beating most of them the only ones i do not see him winning is Leonard and Hearns. Hearns i can not see how the fuck Mayweather can win it i just don't see it at all. The height and boxing skills of Hearns would be to much for Mayweather how would he knock Hearns out i just don't see it. As for Leonard he had reach and height over Mayweather and was just as well rounded and far more active. I would of loved to see the fights though but for now we can only really guess who would win.
