I suppose it is to late to even consider Ricardo Lopez Michael Carbajal Pascual Perez Khaosai Galaxy Eder Jofre Wilfredo Gomez Willie Pep Naseem Hamed Benny Leonard Joe Gans Duilio Loi Nicolino Locche Emile Griffith Wilfred Benitez and Sugar Ray Robinson eh? And then what do we do with Harry Greb? Everyone who ever saw him commented on his unbelieveable speed. Jack Johnson wanted to manage him saying he was the fastest man his size he ever saw. Jack Dempsey said he was faster than Benny Leonard (lightweight champ know for his blazing speed). In 1996 Ring Magazine voted Jimmy McLarnin as the fifth-greatest welterweight of all time - McLarnin said if you thought I was great you should have seen Harry Greb. But there is no film so he couldn't possibly be fast...
Ali said, "I'm so fast that I turn the light switch out and I'm in bed before the lights out" Now he really was the fastest:rofl
Strictly Handspeed: Sugar Ray Leonard fastet period; he threw combos that never seemed to end, and they were all pinpoint. Pound for Pound I gotta go with Tyson though. No heavyweight ever had hands as quick and devastating as his.
