Going to the games has nothing to do with being a fan. With the cost of NFL tickets, fuck if I'm going to a Colts game any time soon.
With your friend, he can stay in the comfort of his own home, not have to overpay for beer, no driving, no parking, probably a better view, hopefully cleaner and more available bathrooms, his seat his a comfy couch, and he can watch it naked if he wants. Try that at a game.
For me, if Peyton is the only Colts player you know, get outta here.
