When I was in college, 3 of my flatmates were aspiring sports announcers. Consequently, the only television in the apartment had sports ONLY on it. Except for the occasional break to watch Seinfield.
Since they were so knowledgeable about the game and could do play-by-play and do color commentary as good as the guys on TV, a lot of times we let them practice their craft while we watched the games muted.
Anyway, after so much sports overload, I think I've actually watched a total of 20 sports events (or attended) in the last 15 years. We almost always watch the Super Bowl (80% for the advertising innovations versus the game) Not that I don't enjoy a game here and there but I've seen it taken to extremes and my interests lie elsewhere.
