Calzaghe, And his handspeed is truely unique when you look at what weightclass he is compared to all the other fast boxers, So Calzaghe is number 1 for handspeed.
at his age, division - and that it's mutliple punches compared to 1-3 punches, calzaghe needs a big mention. that and he's just as fast in the 12th round as he is in the 1st - which is very impressive.
Its funny no one has named Amir Khan, he gave Manny Pacquiao problems in sparring with his hand speed. I guess you guys in the U.S have not seen much of Khan. Here a clip from a Khan fight 1st round from ringside. Crazy Fast http://uk.youtube.com/watch?v=L6Usi3GRLF0
