I guess the question would be......WHY?
1. CTE causing the sport to lose fans? A lot of outspoken former players saying "I'll never let my kid play football" doesn't help.
2. Pathetic play by the players.......this is a league of the QB.......sad reality is, the QB's (as a whole) SUCK! Games aren't fun to watch anymore for a lot of people.
3. Too many commercials..........no explanation needed.
4. Season is too long........you have 4 preseason games and then 16 regular season games and then the playoffs........just like MLB playing 81 home games, it's hard to fill up the stadiums every home game, especially when the opposing team (or home team) SUCKS!
5. Ticket prices = too much; NFL satellite packages = too expensive. I have the NFL Sunday Ticket, but it's getting to be too expensive anymore.
6. People have "cut the cord"........
7. Politics........sure, the anthem debate has costed some viewership.....
My point about all this is..........if anyone tries to say "I told you so" that the viewership is down do to just one thing, they are sadly mistaken. The NFL ratings are just like what happened to Pro Wrestling, NASCAR, etc. The product isn't as good as it used to be, it's still being marketed and priced as if it is greater, and the people aren't buying it.
