Hearns would be a terrible match up for Mayweather his reach and power would be all she wrote. Hearns has a 80 inch reach dude Mayweather has always had the reach over his opponents. So if he can not outbox Hearns which no one ever did he would have to go for the kill and unlike Leonard his offense was not as good and i really do not think his chin would hold up if he went for the kill. As for Leonard i just think he would outwork Mayweather at ww not sure how Bentiez fight would go very boring. Duran Mayweather best beat but Jlc did give him a lot of problems. I think pac gets smashed by all the guys from the 80's because they were to big and were to fast and to well trained. Also when were talking about atg Mayweather is in the top 15 and pac i would say is in top 25 in my rankings anyhow.
