UNC coach Roy Williams says Nike has never helped Tar Heels land recruits

North Carolina coach Roy Williams claims he was stunned to hear of the FBI's findings last week

Last week, an FBI investigation unearthed what U.S. Attorney Joon Kim termed as the "dark underbelly" of college basketball. 10 individuals in and around the sport –- including four Division I assistant coaches –- were charged and arrested in corruption and bribery schemes that put the dealings of shoe companies, the schools they sponsor, and the intricacies of recruiting into question.

While the scandal has brought about plenty of doubt about some programs and coaches within the sport, Roy Williams, coach at Nike-sponsored North Carolina, says the Tar Heels program haven't benefited from the prominent apparel company to secure commitments of top recruits.

"They've never helped me get any player, never insinuated, never done anything," Williams told ESPN.

Williams added that he was "stunned" when he first heard the news that four college basketball assistants from Oklahoma State, USC, Auburn and Arizona were arrested and charged by the FBI. And while it's easy to label the sport as dirty after the FBI evidence was brought to light, he feels it's unfair to tag the entire sport dirty.

"I know it looks really bad," Williams said. "I don't know. I don't enjoy that part. But to paint the entire college basketball world like this I don't think it's fair either because I don't think that's what the entire college basketball world is all about. But it was just a shock to me."

Although North Carolina wasn't implicated in the FBI's findings last week, the program is dealing with its own investigation by the NCAA stemming from allegations that the school allowed student-athletes to participate in fake classes in an effort to retain eligibility. That investigation, which began in 2010, is still ongoing and has no immediate end in sight.
