Mayweather is real fast but watching him he doesnt compare to say roy jones who has freaky hanspeed. Mayweather has stupid shoulder roll and he turns his back in the ring, a good fighter would punch him in the back each time he did that bull!!!. Their is a difference between quickness and hanspeed, mayweather has great handpseed and is elusiv eon nhis feet. Whitaker was quick on his feet and had great ring genral ship, angles sitting in the pocket making you miss, he was adefensive master, Whitaker made chavez look foolish a fighter ten times bette rthan castillo who mayweather struggled with enough said
