I'm from Detroit. We're saddled with the Lions. This means I've never faced a scenario where I actually care about the outcome of a Super Bowl. For me, the game is more about having friends over, opening a bottle of Pappy Van Winkle, and stirring up a massive pot of my award-winning* chili. We watch the game, the ads, and the usually-terrible halftime show without any real investment in the winners and losers.
It's an "entertainment thing" more than a "sports thing."
