The case for Jon Jones
Widely regarded as the most complete fighter the sport has produced, Jones holds a record of 28-1 with the lone loss a controversial 2009 disqualification for illegal downward elbows against Matt Hamill — a fight he was dominating. He became the youngest UFC champion in history at 23 by stopping Shogun Rua at UFC 128 in 2011, then ruled light heavyweight for nearly a decade, beating Daniel Cormier, Alexander Gustafsson, Lyoto Machida, Vitor Belfort, Glover Teixeira, Thiago Santos and Dominick Reyes. In 2023 he moved up to heavyweight and submitted Ciryl Gane for the vacant title at UFC 285, then stopped former champion Stipe Miocic with a spinning back kick to the body at UFC 309 in 2024. His unmatched reach, creativity and fight IQ are shadowed only by suspensions and legal issues outside the cage.
The case for Conor McGregor
The biggest star the sport has ever produced, McGregor changed MMA's economics and reach while backing it up in the cage during his prime. He became the first fighter to hold two UFC titles simultaneously, knocking out featherweight king José Aldo in a record 13 seconds at UFC 194 in 2015 and stopping Eddie Alvarez for the lightweight belt at UFC 205 in 2016. His left hand was one of the most feared weapons in the sport, and his self-promotion filled arenas and drove the two biggest pay-per-views in company history. He also crossed into boxing for a blockbuster loss to Floyd Mayweather in 2017. Injuries, inactivity and losses to Nate Diaz and Khabib Nurmagomedov, plus a leg break against Dustin Poirier in 2021, clouded his later years. He sits around 22-6, but his peak dominance and cultural impact are undeniable.
