The case for Georges St-Pierre
The most dominant welterweight in history and a paragon of preparation, GSP retired at 26-2 having avenged both losses. He first won the welterweight title from Matt Hughes at UFC 65 in 2006, suffered a stunning upset knockout by Matt Serra in 2007, then reclaimed the belt and never lost again, defending it nine consecutive times against a murderer's row that included B.J. Penn, Jon Fitch, Thiago Alves, Jake Shields and Nick Diaz. Famous for tailoring a specific game plan to every opponent — wrestling strikers and out-striking wrestlers — he combined an elite jab with suffocating top control. After a four-year hiatus he returned at UFC 217 in 2017 to submit middleweight champion Michael Bisping, becoming a two-division titleholder, then retired on top. His run of 13 title-fight wins stood as a record and his professionalism reshaped the sport.
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.
