This is all assuming the NFL is entitled to these massive increases each year. Right now, the entire customer base outside of limited basic subsidises NFL fans. At some point, something has to give.
Not meaning to nitpick, but the increases aren't coming down from the NFL each year. CBS, NBC, Fox, and ESPN all have contracts through 2022. It's not like each year the NFL is saying "Holy crap, we can charge more because we're more popular this year. Tell ESPN they need to pay us another billion this year".
