Middleweight + > Featherweight up to Middle Featherweight and down Overall, hand or foot...Whatever you want to put. My list is pretty much handspeed.. I would say Middy +...Roy Jones Jr Feather to Middle.....Howard Davis Jnr or Meldrick Taylor..maybe even Camacho not much between them. Featherweight down...Benny Leonard, Pep. If there are faster its probably because I havent seen much of them yet so please list away fellas.
To me, the fastest guys I witnessed live on TV that made the biggest impression on me were Hector "Macho" Camacho, Roy Jones, and Mike Tyson, all of course in their respective primes. With Tyson, it was his handspeed, unbelievable for a heavyweight. I am only counting guys I saw live. For example, I have seen tapes of a prime Ali, but I wasn't even born yet.
God, this pains me to say it... Hector Camacho, a true douchebag but blindingly fast. Never saw Meldrick Taylor live but hear he was close.
"Hector Camacho vs. Bazooka Limon" back in '83... Camacho appeared so fast, it freaked me out.... However, Limon was actually kinda' slow.. Runner up: Bruce Lee's hands and feet in "Enter the Dragon" were insane... MR.BILL
