I don't think stopping Mosley will prove he is better than Mayweather. Mayweather likes to outbox his opponents and isn't shy about going to the cards. I've little doubt that Manny is a harder puncher than Floyd and can also land a lot more than Floyd because of his output, but I don't think stopping Mosley proves anything regarding being better than Floyd.

They will need to face one another to decide that. Pac has been a freak since moving above LW. I don't understand how he has managed to carry that speed, power and output and along the way barely flinches when hit by much bigger men. I think it is all too much for Mayweather and Mayweather will get outworked, but that's just an assumption on my part.
