Terence Crawford

Terence Crawford retired the arguments. 42-0, world titles in four weight classes, undisputed champion in two of them — first at super lightweight, then at welterweight after the one-sided masterpiece against Errol Spence Jr. in 2023. When the sport finally got the fight it had begged for, Crawford didn't just win it; he made it look like a sparring session.

The Omaha native is the most complete switch-hitter of the modern era: he starts fights orthodox, downloads his opponent for a round or two, flips to southpaw, and takes over. The mid-fight adjustments are the stuff coaches build film sessions around — Crawford doesn't have a style so much as an answer key.

The final act was the boldest: jumping two divisions to face Canelo Álvarez at super middleweight in 2025, giving away size and betting on craft. It capped a career built on taking the fights everyone said were too risky and making them look routine.

At 38, 'Bud' stands with the greatest Americans to ever do it — and the record book shows the thing every fighter chases and almost none achieve: nobody ever beat him.
