What does Jay-Z have in common with Danny Ainge? If things play out the way we think they will, a hefty fine from NBA Commissioner David Stern. Over the weekend, Hov—a minority owner of the Nets—kicked it with the Kentucky Wildcats in their locker room after they clinched a Final Four berth. Only problem: NBA team personnel are strictly forbidden from fraternizing with college basketball players or their families, which is something Ainge found out the hard way back in 2007 when he sat next to Kevin Durant's mother at the Big 12 Tournament and was fined $30,000 by the league. And now the NBA is investigating whether or not Jay broke the same rule by taking flicks with the 'Cats. D'ah well! We're guessing 30 stacks ain't gonna break Jay's bank, right? [via Eben Gregory]
