Shane Carwin wants to fight Roy Nelson whether in an Octagon or “in the street”

Heavyweight Shane Carwin is one of MMA’s most easy-going big men. He’s educated, a family man, and in general a gentle giant who is far more humble than most of his peers on the roster. However, when it comes to Carwin’s feelings towards Roy Nelson it’s a completely different story.

Carwin and Nelson were feuding before the two earned coaching gigs on the Ultimate Fighter 16 and their proximity on the show has apparently fueled the fire even more.

“I just hate the guy. I’ll fight him in the street. I don’t care. … It’s hard to like a backstabber,” said Carwin in an interview with MMAJunkie Radio. “He’s a bullshi**er. ‘I’ll stab you in the back when you’re not near me, but when you’re near me, let’s shake hands and talk about UFC contracts and try to throw them under the table,’ – the same type of bulls— he always does. I just wasn’t up for it. I didn’t want to talk to the guy (on set). I don’t like him.”

Nelson has also implied Carwin is a steroid user on numerous occasions and sought additional drug testing leading up to their December 15 dance at the Ultimate Fighter 16 Finale. While his behavior may have driven Carwin to the point of wanting to lock horns in the parking lot if need be, it sounds like the hard-hitting heavyweight’s heart was in a much more positive place while coaching his squad on TUF.

Carwin: “I hate Nelson as a person.”

“When they called me, I was hesitant to take this because those eight kids, their lives depend on me and me coaching them and giving them the opportunity to live their dream. That’s very serious,” explained Carwin. “If I can help affect these guys and give them the ability to fight in the UFC and live their dreams, then that’s doing your job. It’s not boosting my ego. I could care less how people perceive me. My job is to those eight guys.”

Carwin’s upcoming clash with Nelson will be his first fight since losing to champion Junior dos Santos in June 2011. He holds an overall record of 12-2 with all twelve of his triumphs involving some form of finish in the opening round of action.
