The case for Muhammad Ali
The most consequential heavyweight case on this list: three-time champion, 56-5 record, and the political stage that outlived the ring. Ali never shared a ring with Mike Tyson — Ali's last fight was December 1981; Tyson's pro debut was March 1985 — so this VS page is peak-era teaching marks, not a real head-to-head.
The case for Julio Cesar Chavez
The greatest Mexican fighter and one of the finest body punchers who ever lived, Chavez was unbeaten in his first 90 professional fights, a run of 89-0-1 spanning 1980 to 1994 that is among the longest in boxing history. He finished roughly 107-6-2 with 86 knockouts and won world titles in three divisions, super featherweight, lightweight and light welterweight. He holds the record for most world title fights, 37, and title-fight wins, 31. His signature nights include the last-second, near-miraculous 12th-round stoppage of Meldrick Taylor in 1990 with the fight slipping away, and a title defense before roughly 132,000 fans at Estadio Azteca in 1993, a record boxing crowd. His method, methodical pressure, a granite chin, and merciless work to the liver and ribs that broke opponents down over rounds, made him a national hero in Mexico and a fixture at the top of pound-for-pound lists through his prime.
