To expand its audience, the UFC embraced regulation by state athletic commissions across the country, forced out street-fight clothing for new Reebok uniforms and limited favors for hardened fighters like Nate Diaz.

“They pick and choose who they want, and I think I was a little politically incorrect,” Diaz said this week while training for his Saturday main-event rematch against Conor McGregor in UFC 202 at T-Mobile Arena in Las Vegas. “I wasn’t the person they wanted to market.”

At least, that was the case before the unexpected turn of events that puts Diaz, 31, in his second headline card in less than six months against McGregor, one of UFC’s most popular draws.

“The biggest fight going on in the world right now is a result of my experience in fighting and understanding the game, because I know a lot of fighters and I’ve been sitting here dissecting it for years,” Diaz (20-10) said.


While studying UFC promotion and action on television during two separate year-long hiatuses in the past three years, Diaz noted how the sharp-tongued wit of Ireland’s McGregor eased his rise through the rankings, and how other fighters made sacrifices to help grow the UFC brand.

Life had already put Nate Diaz in his place, though, so the Stockton fighter was resistant to following the directions of his bosses.

Along with his sister, Nina, and older brother, Nick, Diaz navigated a poor, single-mother childhood, scraping for whatever food, love and education could be gathered.

Jujitsu training provided all three. Nick was the first to take up mixed martial arts and Nate followed him into the gym.


A solid boxer, Nate won the reality television series, “The Ultimate Fighter 5” to claim a guaranteed UFC contract in 2007, won five submission-of-the-night bonuses en route to a 2012 lightweight title shot, then lost to Benson Henderson.

Another defeat followed and after a victory in late 2013, Diaz took a year off before returning to lose to eventual champion Rafael dos Anjos and skip another year.

The Diaz brothers built a loyal fan base, but the anti-authoritarian attitude they showed in pressing for better purses and Nate’s coarse language and behavior in the octagon were tough for UFC executives to tolerate.


Not only has Nate accused everyone in the UFC of being on steroids, but he also ripped Saturday undercard fighter Donald “Cowboy” Cerrone for so being so eager to volunteer for several openings.

“Treat yourself like a business and quit [saying] ‘I’ll fight for free,’” Diaz told MMA reporter Ariel Helwani. “That don’t help nobody. Why wouldn’t they pay us? Because they’ve got dumb [people] like you fighting for free.”

Diaz was mired in the holding pattern of a top-10 lightweight ranking when in late February he was asked to replace an injured dos Anjos as McGregor’s March 5 opponent in the main event of UFC 196.

McGregor, the featherweight champion, agreed to move up from his 145-pound weight class and fight Diaz at 170.


McGregor was still the betting favorite, but in the octagon Diaz clearly landed the heavier punches and McGregor submitted in the second round.

McGregor-Diaz was the bestselling pay-per-view in UFC history.

Their Saturday rematch is generating plenty of attention. And it’s not only because of the charismatic McGregor, but also the veteran Diaz’s defiant attitude that resonates with fans.


“I don’t think [the UFC] realized I was the best market they could’ve got,” Diaz said. “I’m the definition of a real fighter. Now that they’ve stumbled upon me, it’s like, ‘Oh, [wow], maybe we should’ve been marketing him the whole time.’ ”

“I didn’t come from a wrestling background, or any background. If not for this, I’d be walking the streets. From where I’ve come from, I shouldn’t have even made it,” Diaz said.
