I said "other", because I don't follow pro football. In fact, until reading your post I had no idea who was scheduled to play in the Superbowl. All I know is somebody's football was underinflated, which sounds like a kiddie squabble to me.
I won't be watching the game, and have no intention of even watching the commercials. Even so, some of them generally filter through even to me, via news broadcasts about them and so on.
Now, I said I don't follow pro football, but about the Saints - - I do follow the Saints, to some extent. They have surpassed being just a football team, and have become the heart of New Orleans. They gave the city a focal point after the storm, bringing us hope and unity of purpose, and besides, who couldn't like Drew Brees? So, I care if they win (or lose as they did this year), but only because they mean so much to New Orleans.
