Been a fan of this team since 1984 and can't remember really ever missing a game or turning one off for that matter regardless of the score.
Last Monday night was the first time I ever shut off a game in the 4th quarter when still 20-20. I have seen a ton of poor officiating through the years, but this game was the 1st to break me. I went to bed and just looked at the result in the morning to see we won. The game was an absolute clown show and unwatchable for me.
To the OP, yes, the NFL is declining 100% based off above for me.
