10. Josh Koscheck
“Kos” grew up as a mulatto -- half-black, half-white -- in the primarily white town of Waynesburg, Pa. According to a 2010 piece published by Fight! Magazine, the fighter, who was raised by his grandparents, used the racial slurs hurled his way during childhood as motivation in future endeavors. Koscheck established himself as a villain early on in his MMA career by conspiring with roommate Bobby Southworth to hose down a slumbering Chris Leben on the initial season of “The Ultimate Fighter.” The former national champion wrestler at Edinboro University has never shied away from his bad-guy persona, parlaying it into a coaching stint opposite welterweight champion Georges St. Pierre on “The Ultimate Fighter 12.” The Californian came up short in his title bid against GSP at UFC 124, suffering a fractured orbital in the process. A recent -- and bitter -- split with the American Kickboxing Academy has Koscheck situated at the Dethrone Base Camp, where he remains a top 10 talent in the welterweight division.
