I'd submit that college football/basketball are the most exciting sports on TV. You might get an NFL game once every few weeks that lives up to the hype, while there can easily be 3 or 4 a week in these other sports.
Frankly, I was done with the NFL about 5 years ago. I'm just a casual observer now, background noise for a lazy Sunday.
Guess I never realized it, but that's what my football involvement has morphed into also - casual observation. It's on as background noise as I go about the weekend chores. I'll stop by the TV, check the scores and move on for another hour or so.
May i'm just getting older or maybe I just haven't had anything to cheer for for about a decade now. If the Bills and Pats were both 7-2 and fighting for 1st in the division, then my interest level might "improve".
