The only reason you don't hear of NFL slump is that contracts between broadcast networks and the league are negotiated well into the future.

TV cord cutting is on the rise, TV usage is down, having to compete with online and mobile time, ESPN figures drag down the entire Disney empire, ESPN is going through layoffs almost each month, seems like. When the time finally comes for cable networks to re-negotiate the deals, NFL numbers won't look as pretty.

Which means lower expenses, higher consolidation, lower player salaries, etc. It won't disappear entirely, but will be just another sport like NASCAR or horse racing, reaching a rather narrow group of avid followers.
