There's more to Jordan "Big Swingin'" Johnson's decision to move to the Professional Fighters League than the appeal of the $1 million prize. Sure, the money that Johnson states he'll make "responsible adult decisions" with is nice, but there's something else on his mind.

The UFC veteran and undefeated light heavyweight prospect signed with the PFL this season with hopes of proving he's not a failure after falling short of his expectations in his collegiate wrestling career.

Johnson, who will face Maxim Grishin on Thursday at NYCB Live at Nassau Coliseum in Uniondale, New York, has a familiar story.

He was a decorated high school wrestler who moved to Iowa as a senior and placed third in the state tournament. He grappled with elite athletes in Pat Miletich's gym, where MMA stars like Matt Hughes, Jens Pulver and Tim Sylvia trained.
