I think Roberto Duran, but that's just me and that's IMHO. Who do YOU think was the greatest not naming Sugar Ray Robinson?
Mohammed Ali is the greatest from 1970-1980 Ray Leonard is the greatest from 1980-1990 (Duran honorable mention) Roy Jones Jr. is the greatest from 1990-2000 (Whitaker/Chavez honorable mention) Floyd Mayweather is the greatest from 2000-2010 (Pacquiao honorable mention) I find it's easier to place a guy in there respectiver eras than to say all time greatest as it is so hard to compare people who lived and fought in seperate timeframes.
There is no single "greatest" but many great boxers. Ten of the ATGs are: Sam Langford Henry Armstrong Harry Greb Benny Leonard Roberto Duran Sugar Ray Leonard Rocky Marciano Joe Louis Muhammed Ali Willie Pep
Great post. It bemuses me how anyone can start a thread asking who was the greatest, but your not allowed to mention Walker Smith.
