Like most natural-born fighters, brothers Nick and Nate Diaz obviously won't ever grow accustomed to losing.
Nick illustrated this theory when he threatened to retire after each of his last two setbacks to Carlos Condit and Georges St-Pierre at UFC 143 and UFC 158, respectively.
And Nate, who's suffered back-to-back losses to Benson Henderson and Josh Thomson, received a 90-day suspension and a $20,000 fine for his use of a homophobic slur following his devastating loss to "The Punk" at UFC on Fox 7.
Although many believe the Diaz brothers each hit walls because of a hike in competition in recent bouts, their collective behavior outside of the Octagon has been even more alarming and unsavory.
Both Nick and Nate have trained under the tutelage of Cesar Gracie at his academy, Cesar Gracie Jiu-Jitsu, since they were teenagers.
But negative remarks from Nick following his loss over St-Pierre, coupled with Nate's decision to part ways with Gracie as a manager, have led many believe that the brothers should part ways with the coaching legend.
Here are three reasons the Diaz brothers need to leave Cesar Gracie Jiu-Jitsu.
Nick Diaz, Jake Shields and Gilbert Melendez each dominated their respective weight classes in Strikeforce, but the trio has gone 0-4 with four decision losses in UFC title fights under Gracie's watch.
On top of that, Nate Diaz got outclassed by Benson Henderson for a unanimous decision loss in his lone title shot with the company at UFC on Fox 5.
While several fighters in Gracie's stables possess the variables to become world champions, it's not a given that any of them have gotten optimal amounts of psychological or physiological training from Gracie himself.
In five UFC title fights, it seemed evident that diabolical trainers like Greg Jackson and Firas Zahabi put together intricate game plans that always left Gracie stumped by night's end.
Neither fans nor pundits could predict the confession that the always vocal Nick Diaz made following his loss to "GSP" at UFC 158.
After getting outstruck 210-80 and surrendering nine takedowns, Diaz took center-stage at the UFC 158 post-fight press conference and essentially blamed his inner circle for his shortcomings against GSP.
In the midst of his rant, the Californian hurled passive-aggressive insults at his coaches and training partners at Cesar Gracie Jiu Jitsu by saying:
Cesar knew I had it coming. Everybody knew I had it coming. And then as soon as I had it coming, nobody was around to help me. The only ones that came to help me was my sambo coach Gil Castillo. You know, Jake (Shields) and Gil (Melendez) they can't train hard right now. They have fights coming up. They've got stuff going on, and they need to have their downtime when it's downtime. I can't go roughing those guys up just because I need training.
For some, like Rashad Evans and Melvin Guillard, who left Jackson's MMA in New Mexico and moved 2,000 miles east to the Blackzillians camp in Florida, trying to mend what didn't need fixed just made no sense.
But for others, like former UFC heavyweight champ Frank Mir, leaving the comfortable confides of his hometown of Las Vegas to train permanently at Jackson's MMA has proven a fitting remedy.
Although Mir dropped his bout to Daniel Cormier at UFC on Fox 7, his first since switching camps, the soon-to-be 34-year-old admitted in an interview with The Las Vegas Sun that he felt reinvigorated by the move.
It will be a permanent move. I very much enjoyed it down there. I thought the preparation for the fight was the best I had ever done. Regardless of the outcome — I think a lot of people would say, if I lose I wouldn’t consider the move to be justified, but I don’t agree — it was a great experience and I’ll be back to do it again.
A semi-permanent move to a camp like Jackson's MMA or the American Kickboxing Academy could do wanders for the Diaz brothers.
Truth be told, unlike trainers like Jackson and Javier Mendez (AKA), Gracie just can't optimize the training of Nick or Nate.
On top of that, Gracie has shown perpetually that he can't control the outlandish behavior that sometimes lands the Diaz brothers in precarious positions.
