I follow the NFL just as much as I used to, but I watch the games a lot less. IN the past (10+ years ago), I had season tickets to the bills, watched EVERY MINUTE of every road game they played, and usually watched 90% of the other games on TV. Now, I'm down to watching 50% of the Bills games and maybe 1 or 2 other NFL games per month.
However, I still follow the NFL as much as I did. I don't play fantasy, but I still read all the boxscores, read recaps of the games, listen to a bit of talk radio (not too much). So what has changed? I can think of 2 main things:
1. I HATE the personality of the commentators. Some of my friends say i'm "not fun", but I don't want ex players or loud mouth media guys shouting at each other and debating if every other player is the best ever week after week. I don't really want their opinions (I hate hearing their opinions most of the time), what I want is to have someone report the facts. It has gotten so bad, I tune out most of the time, literally.
2. There is very little chance in any game I am going to see something I haven't seen already. Sure, every game is different and the players are different, but nothing really jumps out at me. I still enjoy the game to a certain extent, but after years and years, you don't have much new to look forward to.
