I never even thought Prime Mosley could beat PBF let alone now... THe problem with Mosley is he isn't a good boxer. He looks like a robot, granted a robot moving at lightning speeds, but a robot all the same. He can't transist between offense and defense very fluidly, and he doesn't have nor ever had the footspeed or reflexes of Zab, and still Judah was hit by Mayweather once he found his rythym. Shane was a good athlete, but alot of his handspeed which is impressive was overexaggerated like alot of guys because he threw combinations, and his power allowed him to throw large combinations... I can only shudder when thinking about how fast Mayweather would look if he threw those short punch combinations because he still throws fast combinations following through with every punch. This is why I think people thought Mosley was so much slower, but in reality the only reason he looked so much slower than when he was young is that he stopped throwing combinations, and people saw that his handspeed in comparison to his age isn't like Roy's or PBF's IMO.
