30 little-known facts about Floyd Mayweather Jr.

14. Mayweather has won lineal titles in four weight classes, and world titles in five

Although Floyd Mayweather Jr. has certainly acted in ways that call his character into serious question, his boxing record is practically unimpeachable. Yes, Mayweather has either delayed or avoided certain challenges during his lengthy career, but he’s arguably — not clearly — distinguished himself as the greatest fighter of his generation.

That Mayweather has won lineal titles in four weight classes — junior lightweight, lightweight, welterweight (twice) and junior welterweight — is remarkable and places him in fitting company; Mayweather’s generational rival, Manny Pacquiao, ruled five divisions outright. Mayweather’s ability to climb five weight classes also places him in an elite pantheon of greats alongside the likes of Sugar Ray Leonard, Thomas Hearns, Oscar De La Hoya and Pacquiao.

Mayweather’s lineal title reigns at junior lightweight (1998-2002) and welterweight (2006-2008 and 2010-2015) were particularly lengthy and impressive. At 130 pounds, Mayweather scored what arguably stands up as his most impressive win: a 10-round evisceration of then-undefeated Diego Corrales. At welterweight, the interruption of Mayweather’s reign came thanks to his decision to retire, and his 2010-15 stretch as champion included his schooling of a precocious but inexperienced Canelo Alvarez and his comfortable decision win over Manny Pacquiao in boxing’s most lucrative fight.

Given all the substantive things Mayweather has accomplished in boxing, it’s laughable to suggest that his upcoming fight against Conor McGregor has anything to do with legacy.
