Oscar is a fine boxer, but Hearns was too. This is important because I don't think Oscar would want to get anywhere near Hearns' power. I think Oscar's best chance would be to box him, wait for Hearns to tire (which was his biggest weakness at 147), and then out point him and/or catch him with something big. Out of most of the hypothetical matchups for Oscar, I think that this is probably one of the worst.

I don't think Oscar could get to him in time. Eventually Hearns' right hand would fall out of the sky, probably sooner rather than later, and the whole thing would be over. I'd have to say Hearns by KO.
