It's true that revenue sharing levels the playing field In the NFL ... but league revenues are more than just the TV contracts:

"In the early days, the NFL's salary cap was based off its gross revenue, which included money earned from national television contracts, ticket sales and merchandise sales. In 2006, the cap included such things as naming rights for stadiums, sales of premium seats and local advertising. As of 2014, the cap includes all streams of revenue."
