Baldomir said Zab was faster before he fought Mayweather, and by then Mayweather was already way above his natural weight... when they fought eachother the first half Zab in terms of time it took for his glove to get out and back(clocked) was a little faster than Mayweather becuase of the first 3 and a half rounds, but after that Mayweather's handspeed was faster than Zab's for the rest of the fight and even faster than Zab at the begining, but by a negligible amount I think it was the size and color of their gloves that threw people off. Also Mayweather throws a lot faster punches when he doesn't have his hands right beside his head.

Regardless as about ROy JOnes Jr. he was not faster than Mayweather prime for prime, not even close, was he faster pound for pound? For sure, but watch Mayweather up to 140, hell even now and you'll see that besides combinations he has quicker hands than ROy... Many times I've watched Roy, in his prime and at LHW, then threw in a fight of FLoyd against Dela HOya, or Baldomir or against Judah and the speed is a little faster. SO Floyd at WW is still faster than Roy in his prime, and Floyd used to be way faster than he is now.
