It's official. Kevin Durant has signed to Jay-Z's Roc Nation Sports agency. Earlier today, KD posted a photo on Instagram of himself and Hov inking the deal, which has been rumored to be in the works for several weeks. "Grateful for this opportunity with Roc Nation Sports. It's go time" reads the caption. On June 19, Jay-Z became officially licensed to work as an NBA agent, selling his stake in the New Jersey Nets to do so. Durant recently left his former agency Landmark Sports and will be the first NBA client for the agency, who also represents Yankees second baseman Robinson Cano and New York Giants wide receiver Victor Cruz.
