You're insane if you think the NFL or NBA are going to fold or go bankrupt anytime soon. TV in general is down it's not simply sports. Viewing habits of people via streaming services and such are what has caused it. Sports are the only reason many people (myself included) want or have cable at this point. Why watch whatever garbage Fox or ABC is making me watch full of commercials when I can just watch literally exactly what I want commercial free via streaming service?
