The case for Anderson Silva
For seven years 'The Spider' was untouchable, holding the longest title reign in UFC history at 2,457 days and a record 16 consecutive victories with 10 straight middleweight title defenses. His striking looked like something from another sport: the front-kick knockout of Vitor Belfort at UFC 126 in 2011, the matrix-like head movement, the finishes of Rich Franklin, Forrest Griffin, Chael Sonnen and Chris Leben. He fought with his hands down and made elite opponents miss by inches before countering with fight-ending precision, and he twice moved up to light heavyweight and won. His aura finally cracked when Chris Weidman knocked him out at UFC 162 in 2013, and the 2013 rematch ended horrifically when Silva broke his leg on a checked kick. He retired 34-11, but at his peak he was the most artistic finisher the sport has seen.
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.
