6. Royce Gracie
The man credited with putting the UFC on the map also helped spread the Brazilian jiu-jitsu gospel across America. As such, his importance to MMA cannot be denied.
Gracie moved over to Pride in 2000 and fought Japanese legend Kazushi Sakuraba in what some consider the greatest fight in MMA history. The Brazilian’s corner threw in the towel after six grueling 15-minute rounds. Gracie fought sporadically after the historic encounter, cementing his place on MMA’s Mount Rushmore long before his ill-conceived battle with Matt Hughes in 2006. He was flagged for anabolic steroids after defeating Sakuraba in their rematch on June 2, 2007.
