I would go to the Chargers game. I went to the Cowboys//Redcoats game a couple years ago when we were 13-2 and it ended up being a pointless "let's try to win, but not really because we're already the number 1 seed in the playoffs and when the Redcoats blow us out, we'll just pull all our starters and pretend we never intended to win the game in the first place" game. Huge waste of money!
Although I doubt this years game against Philly will be that type of game, it very well could turn out that way if we put ourselves in a good situation the next few weeks.
