Three executives have been brought on to head CAA Sports, a new division of Century City-based Creative Artists Agency. The division will be led by Howard Nuchow, who most recently was president of Peter Guber's Mandalay Sports Entertainment; David Rone, who had been executive VP of Fox Sports Networks; and Michael Levine, who had been president of Van Wagner Sports Group. The agency already represents more than 300 athletes (including Matt Leinart). Most recently, CAA helped broker the David Beckham deal.Variety
