I'm surprised he picked Mayweather to beat Hearns but not Leonard. Of the 2, Leonard should be the easier fight since his main advantage over Hearns was having a better chin and Mayweather doesn't really hove the power to exploit Hearn's questionable chin. I am fairly confident that Mayweather could beat Leonard, but I'm not sure about Hearns.
Duran was at his best at lightweight. After he started moving up in weight he lost more big fights than he won and he only beat Leonard in the first fight because Leonard fought his fight and tried to brawl with him instead of keeping his distance and outboxing him. Mayweather is too smart and calculating to fight Duran's fight, so he should be able to potshot his way to a UD win. With a prime Duran at 135 it might be different.
