Justin Gaethje
Vitals
The Read
Gaethje is one of the heaviest hitters the lightweight division has produced — 20 of his 27 wins are knockouts — built around blistering low kicks, a relentless pace, and a willingness to trade that has made every fight a fan favourite. Under Trevor Wittman he has added discipline to the chaos, picking his moments instead of brawling every second.
The career arc shows both sides: a one-punch knockout of Dustin Poirier and decision wins over Rafael Fiziev and Paddy Pimblett, but also a last-second knockout loss to Max Holloway. At 37, the questions are mileage and whether his chin holds against elite power over championship rounds.
