Big John McCarthy is often considered the standard for what people consider the best UFC referees. He was one of the first UFC referees and set the standard for the job.

John was an ex-police officer who got into reffing through the Gracie family. He trained at the Gracie Academy early on when Rorion was helping create the UFC.

Originally, Big John wanted to fight, but Rorions didn’t let him. Instead, Rorion let John be a referee from the second UFC on.

That was when Big John would yell his iconic trademark to start a fight: “Let’s get it on!”

Not only is Big John the standard for MMA officiating, but he also helped establish many of the sport’s rules. Every fan and fighter owes Big John McCarthy a little gratitude for his work in MMA.
