The NFL's players have put a number on how much money the league should pay back if it loses a court fight over $4 billion in television revenue. Exact amounts aren't yet known, but the figure is certainly in the hundreds of millions of dollars. The players requested revenue "left on the table" in 2009 and 2010 when the NFL re-negotiated broadcast contracts. U.S. District Judge David Doty ruled earlier this month that the league failed to maximize revenue for both sides to share when it reached the new deals.
