Stupid Question about 17-Game Question

But whats the revenue compared to during games, pre game, and post game vs coverage of NFL through shows such as ESPN Get Up or Good Morning Football? Does the NFL even get money through those shows or mainly during game broadcasts cause of commercials. If most of the revenues comes through game broadcasts then adding bye weeks wouldn't help them because it doesn't increase the amount of games.
Networks pay the NFL to broadcast the games based on how many games they show.
Networks can only show 4 games per week maximum, unless the NFL sells the Thursday night game. Adding a bye week will add 4 more games per season a network could show.
I believe the networks get the advertisement money.
