The NCAA has opened an investigation into North Carolina guard PJ Hairston’s connection with NBA agent Rodney Blackstock, Big Lead Sports has learned. According to a source, an NCAA investigator met with a University of North Carolina compliance officer this week regarding the relationship between the Tar Heels’ leading scorer from last season and Blackstock, who played at UNC-Greensboro a decade ago. Blackstock was in the news recently when it was revealed that he paid the AAU coach of Kansas star Ben McLemore thousands of dollars “on behalf of sports agents and financial advisers” who were courting McLemore. Emily Potter, the NCAA’s associate director of public and media relations said via email: “it is our policy to not comment on current, pending or potential investigations.” The UNC compliance officer who took part in the meeting with the NCAA didn’t return an email or phone call, but said through school spokesperson Steve Kirschner, “The NCAA and its member schools are continuously engaged in efforts to educate, monitor, investigate and report. We do not comment on compliance issues or the reported activities of the NCAA.” Hairston, like Blackstock, is from Greensboro, and a source tells Big Lead Sports the two have known each other for years, and became much closer last year when Hairston emerged as North Carolina’s best player.
