Roy Jones Meldrick Taylor SRL Pernell Whitaker IMO, he can put his punches 2gether Zab Judah Floyd MAyweather Jr ( Sr. has fast hands 2) Shane Mosley up and coming chad dawson
If this is all time? Pacman isn't rated anywhere near that high. And not ahead of Leonard either. Taylor, Camacho, Jones, Mosley, Leonard
But even throwing that particular combo, he is not as fast as the above mentioned. Judah threw a faster 1-2 than Pacman does now. Pacman is very very fast....but he isn't quite as fast as those guys.
I remember Holyfield used to throw punches so fast that his hands would appear to be still. All you could hear was the noise of him hitting his opponents to know that he was actually landing punches. It sounded like furniture breaking.
