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.
The case for Henry Armstrong
Armstrong achieved the single most astonishing feat in boxing history: for several months in 1938 he simultaneously held world titles at featherweight, lightweight and welterweight, three divisions at once, a feat impossible under modern rules and never equaled. Nicknamed Homicide Hank and Hammerin' Hank, he fought at a suffocating, non-stop pace behind a peculiarly low heart rate that let him throw punches other men could not sustain. His record of roughly 151-21-9 with 101 knockouts includes a 1937 run of 27 straight wins, 22 by knockout, and 19 successful welterweight title defenses in barely two years. He beat Barney Ross, Lou Ambers and a who's who of the lighter divisions. Only a disputed draw with Ceferino Garcia denied him a fourth title in a fourth division. For sheer output, pressure and simultaneous multi-division mastery, no one else in the sport's history comes close.
