Should I take her to the football game?

My girlfriend is loving, fun, breathtakingly beautiful, educated (a doctor) and she puts up with me (amazing).
She is also a “foreigner” (Iran) who knows nothing…NOTHING…about American football.
I have two tickets to the big game this Sat.
I could take her and she would enjoy my company and the tail-gaiting etc.
But she would be totally mystified by the game.
I could also take one of my buddies who would be eternally grateful and be in my debt until the cows came home.
She would not really care. She would go shopping or something and meet me after the game.
Still, I think she would like it if I asked her to go.
Advice?
