Nick Newell has been described as a "human interest" story and an "inspiration" due to the fact that he's overcome having a congenital amputation. He's had to deal with people saying that he doesn't belong in Mixed Martial Arts (MMA) and that he's really just a fighter who's wasting everyone's time. He entered the World Series of Fighting 4 (WSOF) cage last night (August 10, 2013) as a 8-0 lightweight and proved that not only is he a fighter, he's actually pretty good. His opponent, Keon Caldwell, was a solid step up in competition, and Newell still made it look easy. His "disability" works to his advantage as he's found a way to lock in tight submissions. The guillotine finish was one of the slickest you'll see and he forced the tap two minutes into the first round. He's definitely the fighter that the young promotion should put their marketing behind.
