Roy Williams radio show notes: Hairston, injuries, suits Posted Jan 15, 2013 P.J. Hairston has been invaluable to UNC this season. He’s averaging 12.3 points and 4.4 rebounds; he’s expanded his offensive game; he’s improved his defense; he plays the "4" when the Tar Heels go to a smaller lineup; and he scored a career-high 23 points to help his team win at Florida State last Saturday. And it sounds like he’ll continue to do all of those things in a reserve role. (ESPN.com)
