The NFL's locked-out players asked a federal judge Thursday for at least $707 million in damages stemming from a dispute with the league over $4 billion in broadcast revenue. U.S. District Judge David Doty took the request under advisement after a two-hour hearing that included arguments from attorneys for the league and the players. Such an award could amount to a huge piece of leverage in the players' fight with the NFL over the next collective bargaining agreement.
