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 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.
