Big John’s time as a police officer
John McCarthy grew up in the LA area and is the son of Police Officer Ronald McCarthy. When John grew up, he and his brother Ronald Jr would become police officers like their father.
Big John McCarthy joined the LAPD in 1985 and did a number of jobs within the department. He was actually with the LAPD from 1985-2007.
All while officiating MMA events across the world multiple times a month. For two decades, McCarthy’s main job within the department was being the head tactics and self defense instructor.
A job that McCarthy held from August of 1993 until his retirement in 2007.
Big John begins training with the Gracie’s
John began training with Rorion Gracie at the Gracie Academy in Torrance during the early 1990s. Rorion had this program for employees of law enforcement called GRAPLE. (Gracie Resisting Attack Procedures for Law Enforcement)
The reason why McCarthy started training with the Gracie’s was due to the Rodney King riots during the early 1990s. After the riots, the LAPD realized that their officers had no skill of subduing a suspect without using their nightsticks or clubs.
This is how they got in contact with the Gracie’s and officers began learning how to physically hold down suspects. Without the use of their weapons.
At first, McCarthy was skeptical of the power of Jiu Jitsu like most were at the time. Since John is a very large man, he figured he could use his size to beat Jiu Jitsu.
He, like everyone before him, was quickly proven wrong and easily dispatched by a few of the Gracie family members. From that point on, Big John was sold on Jiu Jitsu and would become a life long practitioner.
McCarthy would get his GRAPLE certification in 1993. Which in turn would get him the head self-defense instructor position at the LAPD, which he held for 14 years.
Big John McCarthy wanted to fight in the UFC
Initially when Rorion and Art Davie were putting together the UFC, McCarthy expressed interest in fighting. His instructor Rorion quickly turned John down for a number of reasons.
The main reason being that he wanted a member of the Gracie family to represent Jiu Jitsu at the tournament. Also he felt if they put in a giant of a man like John it would defeat the purpose of showing the power of Jiu Jitsu.
They needed someone that was smaller and unassuming like Royce to compete in the tournament. It turned out that Royce was the correct choice as Jiu Jitsu exploded in popularity. It also laid the groundwork for the UFC to become a sport.
How did John McCarthy get the nickname “Big John?”
McCarthy actually got the nickname from the original co-owner of the UFC, Art Davie. The former owner of the UFC dubbed McCarthy “Big John” after he lifted Davie in the air with both hands.
The nickname stuck and now everyone has been referring to McCarthy as Big John for almost 30 years.
Big John McCarthy and the early UFC fights
Even though Rorion turned John down for his offer to fight in the UFC, he did have another idea. Rorion thought with his large stature and law enforcement background that he would be a great referee.
Since the early UFC fights were anything goes, they needed some that were big and could stop the fights. John turned out to be the perfect candidate.
He would make his officiating debut at UFC 2: No Way Out in 1994. Big John McCarthy large size and demeanor immediately made him stand out to fight fans.
Then he would say the patented catch phrase that he borrowed from boxing referee Mills Lane. “Let’s get it on!”
In the early UFC, there were basically no rules, except for eye gouging. The fighters could do just about anything they wanted aside from killing their opponent.
So since there were no rules, it was John’s job to stop the fighters from killing each other. If a fighter got knocked out or submitted, he would step in to protect them.
Did Big John create the term “MMA?”
In order for Big John McCarthy to be allowed to officiate at UFC 2, he had to get a work release from the LAPD. In the paperwork that he had to fill out to get approved, he had to say exactly what the job was.
At the time, the UFC matches were no holds barred fights, so he couldn’t put that in the paperwork. So instead, Big John McCarthy wrote martial arts referee, but his superiors wanted to know what kind of martial arts?
John replied with “mixed martial arts referee.” Now, Big John McCarthy has never claimed that he came up with the name mixed martial arts.
There was said to be a sports columnist from the LA Times that coined the term beforehand when he covered UFC-1.
Whoever came up with the name, MMA stuck and everyone has referred to it as that ever since.
The UFC gets sold to Zuffa
From UFC 2 to UFC 29, McCarthy was employed within the UFC by Art Davie and Bob Meyrowitz. In 2001, Meyrowitz and Davie would sell the UFC to the production company Zuffa.
The new owners of the UFC were the Fertitta brothers, Loreno and Frank, along with Dana White as the new president. Big John would continue working with the UFC and help further develop the sport.
Big John McCarthy was one of the creators of the UFC’s initial rule set before the unified rules were established.
Big John McCarthy helps create the official rules of MMA
When MMA started to become a legitimate sport, each promotion at the time had their own rules. This would create chaos within states trying to oversee events as no one promotion’s rule sets were the same.
The athletic state commission of New Jersey was the governing body that would help create the unified rules of MMA. They invited numerous different MMA promotions along with Big John and the UFC to a meeting to create official MMA rules.
All of the rules that are followed today by MMA organizations within the US follow the rules established from this meeting. Everything from the rules against grabbing the fence or kicking a downed opponent to the head.
Big John McCarthy and the 12-6 elbow
During this meeting was where the highly criticized 12-6 elbow rule was established. Something that Big John McCarthy adamantly fought against.
He went back and forth with Dr Dom Coletta on the danger of the 12-6 elbow. The NJ commission actually wanted to get rid of all elbows in MMA, but McCarthy talked them out of doing that.
Dr Coletta still had a problem with one elbow and that was the 12-6 elbow. He and the NJ commission had seen Karate demonstrations, where 12-6 elbows were used to break various objects.
John tried to debate Coletta, but Lorenzo Fertitta told him to back down. From then on every type of elbow is illegal, except for the 12-6 elbow.
