The case for Sugar Ray Robinson
Robinson is the fighter the phrase pound-for-pound was invented to describe, and The Ring's choice as the greatest of all time. He compiled a record of roughly 173-19-6 with 108 knockouts across 200 professional bouts and 25 years, and for a stretch was untouchable: he won his first 40 fights and was unbeaten for 91 consecutive bouts between 1943 and 1951. He held the welterweight crown, then won the middleweight title five separate times, the last at 37, beating Hall of Famers like Jake LaMotta, whom he defeated five times in six meetings, Kid Gavilan, Carmen Basilio and Gene Fullmer. His blend of one-punch power in either hand, hand speed, footwork and finishing instinct set the template every all-around great is measured against. Even in decline he was dangerous, and his combination of volume, dominance and artistry over a quarter century has never been matched.
The case for Muhammad Ali
The most consequential figure in boxing history and, by his own and much of the world's reckoning, the greatest heavyweight. Ali finished 56-5 with 37 knockouts, but his record undersells him: a draft-refusal exile stole three-and-a-half prime years, and he returned to win the title twice more, becoming the first three-time lineal heavyweight champion. He beat a murderer's row of champions, Sonny Liston, Joe Frazier, George Foreman and Ken Norton, in fights that defined the sport: the 1964 Liston upset, the Fight of the Century, the Rumble in the Jungle, and the Thrilla in Manila. As a young heavyweight he moved and jabbed like a middleweight, revolutionizing what a big man could do; as an older one he showed extraordinary chin and ring guile with the rope-a-dope. His athletic gifts, showmanship and moral courage made him the most recognized athlete on earth.
