Sugar Ray Leonard is the h2h goat at 147, he comprehensively beats Robinson

Leonard is more skilled than Robinson, can match his speed, has better footwork, better defense. Robinson has a superior offensive arsenal and power but he would get outboxed. Leonard beats Crawford and Mayweather in close fights. He would beat Hearns more often than not. He would be too much for prime Pacquiao and Armstrong, KOs Felix Trinidad, beats up De La Hoya and Shane Mosley. Napoles and Griffith get outclassed.

And yes, i believe he beats Duran more often than not.
