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 Manny Pacquiao
The only fighter in history to win world titles in eight weight divisions, Pacquiao climbed from a 106-pound teenager in Manila to a welterweight champion who beat the sport's biggest names. His record of 62-8-2 with 39 knockouts is decorated with lineal titles in four divisions and destructive wins over Oscar De La Hoya, Ricky Hatton, whom he knocked cold in two rounds, Miguel Cotto, Marco Antonio Barrera and Erik Morales in an epic trilogy, and Juan Manuel Marquez in a rivalry of four razor-thin fights. A whirlwind southpaw with blinding speed, an unusual angle of attack and relentless volume, he was named Fighter of the Decade for the 2000s. He carried a nation, becoming a Philippine senator while still fighting at the elite level. Only a controversial loss to Marquez and the long-delayed Mayweather defeat mark an otherwise singular ascent through the weight classes.
