The NFL is printing money:
"ESPN is paying $1.1 billion annually over eight years to broadcast the Monday night games. NBC has a six-year, $3.6 billion deal for the Sunday night package. CBS and Fox are paying a total of $8 billion over six years for the rights to Sunday afternoon games. DirecTV agreed to pay $3.5 billion for a five-year extension that runs through 2010."
Throw in ticket sales, suite sales, licensing, and product sales and there is a ton of cash involved.
With that much cash floating around, I'm not sure the players are being paid enough.
