When that much money is involved I'm sure there are clauses the stipulate a certain level of product must be provided. I think the networks could and should say the NFL is not delivering on the deal that was agreed to in the contract. The network I'm sure did not agree to air the silly political grievances of millionare players. It's likely the NFL is violating the contract by not controlling the actions of it's players.

I would bet on the networks fulfilling the obligations of their NFL contracts as there seems to be no violation of those contracts or the CBA.
However, when the contracts are negotiated, the price may decrease somewhat.
