Floyd was faster below lightweight. Super featherweigh he was blindingly fast. Above lightweight, Manny has shown faster hands and feet. Today, Manny is considerably faster.
Prime for Prime: Mayweather. He may not have faster combos, thats just cause he doesn't like to waste punches, so each shot is thrown with precision. IMO the definition of handspeed is how fast do punch get from point A to point B. And mayweather did it with perfect form as well. Today: Idk, Floyd has slown down, but so has Manny? SOOOoooo.... I guess Manny cause of his footwork, but thats slowed too.
Mosley, who has a very good resume, said that 33 year old Mayweather he fought has the quickest feet he's ever dealt with in his career.
True be told it doesn't matter if he is or isn't because he is fast enough and skillful enough to over come Manny speed if he is faster then Floyd.
