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 Daniel Cormier
A two-time Olympic wrestler and 2008 U.S. team captain, 'DC' translated elite grappling into a two-division championship career, holding both the light heavyweight and heavyweight belts. He captured the vacant light heavyweight title against Anthony Johnson at UFC 187 in 2015, defended it against Johnson again and Alexander Gustafsson, then moved up and knocked out the great Stipe Miocic to take the heavyweight crown at UFC 226 in 2018. His stellar record of 22-3 carries an asterisk that defines his career: every one of his losses came against Jon Jones, and one of those was overturned to a no-contest after Jones failed a drug test. Endlessly durable, technical and cerebral, Cormier would likely be remembered as an all-time great champion in any era that did not also contain his one impossible rival.
