Casey Wasserman’s sports agency brokered the deal announced today for Radio Shack to sponsor 7-time Tour De France winner Lance Armstrong’s new American Pro-Tour cycling team. This past year, Lance’s comeback Astana team had trouble getting a backer and almost had to pull out of the 2009 Tour.) This will be one of the most talked-about sports business stories of the summer, and, more importantly, Lance’s LiveStrong Foundation will benefit from the partnership. The West LA-based Wasserman Media Group was started by the legendary MCA/Universal topper Lew Wasserman’s grandson. Screenwriter Gary Ross (Seabiscuit) was recently put on the long-gestating Lance Armstrong biopic.
