Will Jay-Z actually represent clients of his newly created sports agency, Roc Nation Sports, in contract negotiations? Ron Berkowitz, a spokesman for Roc Nation Sports, confirmed to ESPN.com that, as of this week, Jay-Z is now licensed to work as an NBA agent. Juan Perez, president of Roc Nation Sports, also is now certified with the National Basketball Players Association. The news was first reported by the Sports Business Journal. What's not clear is how soon Jay-Z can represent players. A source close to the situation said that, as of Wednesday, the hip-hop mogul had not sold his small ownership share (less than 1 percent) of the Brooklyn Nets. Source: ESPN
