Hearns wins rather easily in my opinion. His long jab would give Oscar fits.

Since Hearns' right hand was so good, it's easy to forget how skilled of a boxer he was. He dominated most of the two fights he had with Ray Leonard. He was way ahead in the first fight when he ran out of gas and got TKO'd, and he got robbed in their second fight that ended in a draw.

His big weakness was his chin, but Oscar's always been more of a body puncher, I'm not sure if he has the firepower to hurt Hearns upstairs.
