The case for Khabib Nurmagomedov
The most dominant grappler the sport has known, Khabib retired flawless at 29-0, having barely lost a round across his entire career. A multiple-time combat sambo world champion from Dagestan, he built a smothering, cage-crushing wrestling style — 'send them off,' as his father put it — that no opponent solved. He won the vacant lightweight title against Al Iaquinta at UFC 223 in 2018, then defended it in the biggest fight in company history, submitting Conor McGregor by neck crank in the fourth round at UFC 229 before roughly 2.4 million pay-per-view buyers. He followed with submissions of Dustin Poirier and, in his final bout, a third-round triangle choke of Justin Gaethje at UFC 254 in 2020. He retired immediately afterward, honoring a promise to his mother following his father's death, walking away perfect.
The case for Kamaru Usman
'The Nigerian Nightmare' built one of the most dominant welterweight reigns in history on a base of relentless, high-level wrestling that evolved into genuine knockout power. He put together a 15-fight UFC winning streak — among the longest ever — and won the welterweight title from Tyron Woodley at UFC 235 in 2019, then defended it five times. He beat Colby Covington twice in grueling wars, avenged an early loss to Jorge Masvidal with a highlight-reel knockout, and outpointed Gilbert Burns and Leon Edwards. His reign ended dramatically when Edwards landed a head kick with under a minute left in their UFC 278 rematch in 2022, erasing a fight Usman was winning. He sits around 20-4, a wrestler who became a finisher and headlined the sport's African golden age alongside Israel Adesanya and Francis Ngannou.
