"There was nobody I wanted to coach against more than that guy, and to kick his ass in not only coaching, but in the fight as well. [Nelson] bitches and complains all the time. He always has an excuse for everything. He claims to be this average, normal guy and that's who he tries to reach too, the blue-collar workers... He's the farthest thing from a blue-collar worker that he claims to be... There's that much animosity there. All of that stuff is real. The only thing I've ever had to hype for my fights is to just watch my style. My fights are exciting. There doesn't need to be any hype or talk, but this real. I hate the guy. I dislike him. I hate him as a person. That's just it. I'll be vocal about it." -Shane Carwin on Roy Nelson via Bleacher Report.

UFC heavyweight and TUF 16 coach Shane Carwin isn't much for words and trash talk. But his apparent disdain for fellow heavyweight and TUF 16 coach Roy Nelson seems to have pulled him out of his shell.

The powerful heavyweight usually prefers to let his hands do the talking. And talk they do. 

The Denver native finished the first four UFC opponents he faced, each via first round knockout. And these weren't all gimme fights either, names like Frank Mir and Gabriel Gonzaga were among those that fell victim to oversized heavyweight's power and iron chin. 

With big, decisive wins over guys like Mir and Gonzaga on his resume, it wasn't long before Carwin had positioned himself for a title shot, and he was tabbed to face, then champion, Brock Lesnar in July of 2010.

Carwin dominated Lesnar in the fights first frame, rocking the champ and landing heavy bombs on him for nearly the entire last half of the round, he nearly scored a TKO, but he punched himself out and succumbed to exhaustion in the second round, eventually tapping to an arm triangle.

After the fight, the 35-year old began having neck problems and was eventually forced to undergo surgery. He came back a year later and was soundly beaten by current heavyweight champ Junior dos Santos in a three round decision. 

Back surgery followed that fight and another year has passed, but Carwin is again attempting to come back and regain his championship form. He'll do so against Roy Nelson on December 15, 2012 at The Ultimate Fighter 16 Finale live on FX.
