All-time who are the 3 best of each of these weights? No runner-ups or honorable mentions. Just flat out the 3 best you've ever seen. Lightweight Middleweight Heavyweight
Stressing ever seen, in order. 135 - Duran, Whitaker, Leonard 160 - Robinson, Monzon, Hagler HW - Ali, Louis, Lewis
Chronological order: Lightweight is easy, Gans, Leonard, Duran Middleweight is trickier, Fitzsimmons, Greb, Hopkins Heavyweight is easy for the top two (Louis Ali). The other slot is in constant rotation, but I will give it to Jack Johnson today.
