Everybody has a price, everyone except Nate Diaz, who has blasted fighters who have no qualms facing off against their friends.
Lightweight fighter Diaz was highly critical of those who put a price on their friendship, saying that he would never teammate and close friend, Gilbert Melendez - even if was for the title.
The outspoken fighter from Stockton isn't alone in thinking this way, but there are many that have a price for their friendship - including Bantamweight champion, TJ Dillashaw.
Money doesn't mean a thing
In a recent interview, Dillashaw said that he's open to the possibility of fighting mentor, coach and friend, Urijah Faber if the money was right. That didn't sit well with Diaz, and while he didn't call out Dillashaw personally, it's still pretty damning of the Team Alpha Male member.
"I hear people, 'Oh, I'll fight him if we get paid a million dollars.' My partners are my partners and it's not even a consideration. Other people just give hints and 'ifs,' so it makes everyone curious. People are dumb.
"They don't know how to answer the damn question...If someone's even considering talking about fighting you, then what the [expletive] are you friends for? I don't think people even know what friendship is in this sport," Diaz told MMAMania.com.
"When Gil gets the belt, when Gil wins this fight and gets that belt, I won. That's a win for me. That's my brother. That's pretty much my goal here."
Many other fighters feel the same
Light heavyweight contender Daniel Cormier's drop down from the heavyweight division was inspired in part by Cain Velasquez becoming champion. The two regularly train together ahead of fights and are close friends outside of the gym. They would've refused to fight one another, so Dana White managed to get Cormier to drop down a weight class.
Things haven't been so simple in other divisions though, with Faber and Dillashaw unlikely to go up, or down, a class in the near future. Then there's the possibility that Rory MacDonald wins the UFC Welterweight title in his next fight and that would leave the UFC in a spot of bother over the return of Georges St-Pierre.
Like Cormier and Velasquez, MacDonald and St-Pierre are close friends and training buddies and would want to avoid fighting one another - something White has to reject before it's even been set.
Of course he'll want to put on the best fights he can as a promoter, but don't be surprised if friendships cost the UFC some top clashes.
