I don't like Mayweather, but you just can not ignore his skill. He is a boxing legend as much as I hate to say it. In the fight vs Ortiz he showed how brilliant he was (before the KO mess). I expected Ortiz to be in his face, dominate him, but Mayweather simply denied Ortiz everything. Vs Pac, I truly though that Mayweather was ducking him until I looked more into Pac's style. Now I highly doubt that Mayweather is scared if Pac skillwise. If Pac takes the tests Mayweather would love to fight him actually. Mayweather should be able to counter Pac all night long. Only Pac's pressure and stamina might be abit of a problem for him.
Floyd really is no question a total package talent for boxing. But his attitude and disturbing ego ruins himself and the sport.
