at Heavyweight young Muhammed Ali was so fast, there's never been a heavyweight since with that handspeed. Also think he had one of the quickest jabs going too. Mike Tyson was fast, but that was more with hooks and power punches. Ali's jab was superb.

Lower than heavyweight as far as I'm concerned there's one man who rules, thats Roy Jones Jnr. Absolutely incredible handspeed. The most talented boxer that has ever lived in my humble opinion.
