Jay-Z's new agency, Roc Nation Sports, has been the most talked about development in the world of representation since the rap star announced his group was partnering with CAA Sports and signed New York Yankees superstar Robinson Cano on April 1. Now Jay-Z, himself, is now a player agent after the entertainment mogul was certified by the NBA player's association, spokesmen for the union and Roc Nation Sports said Thursday. However, it's unclear exactly what he can do. Jay-Z would have to sell his minor share of the Brooklyn Nets before he can represent players, according to NBA rules, and a Roc Nation spokesman wouldn't comment on whether that has been done. In less than three months, Roc nation Sports has changed the face of sports representation in the eyes of other agencies. Jay-Z's high profile and personal relationships with many big name athletes make him a force to be reckoned with. Many rival agencies consider the marketing mastermind "a magnet" for star athletes and fear the entrepreneur could lure away existing clients with his name alone. Besides Cano, Roc Nation’s website listed two other star athletes last week as clients: WNBA Tulsa Shock guard Skylar Diggins and New York Jets rookie quarterback Geno Smith. CAA Sports co-represents Diggins and Cano for marketing and contract work, but does not co-represent Smith. Since signing Cano, a spokesperson for Roc Nation Sports has said that the plan was to build “a full-service agency” by hiring agents certified to represent athletes in contract work in multiple sports, as well as certifying Roc Nation executives. It sounds like Jay-Z's first order of business as an NBA agent is signing the Oklahoma City Thunder's Kevin Durant. Not a bad first gig on the new job.
