I don't know...to me, it's just a hell of a lot of fun hitting the sports bar with games on everywhere around you...loud as hell, with fans yelling and high fiving everywhere. You always know what's going on in all the games. Plus you eventually start recognizing the same fans there every week and can give each other hell. It's pathetic, but it's fun.
There's a guy who's been coming to the bar I go to for years...huge Cincinnati fan. He was there every damn week even when they were so pathetically bad, and usually all by himself. Last year, of course, there was a crowd of 10-12 Bengals fans there every week. But he's still there, right in the middle. True fan.
