The obvious answer is we play to win the game.
However depending on how tonight's game shakes out will determine how we come out in week 17. If the Philly/Dal game is locked in, we need to avoid key injuries, and get some guys in that normally don't play and see if we can get some other guys some chances to see if they can perform in a meaningful game.
In a lolipop and rainbow world, I wouldn't mind seeing a whole lot of Choice Sunday and a lot of Ogletree. Maybe even take some chances on 4th down that we normally wouldn't take. See if we have anyone else riding the pine that may be of service in case we lose someone. Use this game like a preseason game because to me this is essentially what it is. A preseason game for the real game that will matter a whole lot more than a win or loss next week.
HFA against Philly to me is not going to win or lose us the game. We are just as capable of winning in Philadelphia, as they are in winning here in Arlington. As someone else said, with two teams as well acquainted as we are with them, there's probably nothing either can hide. However if there is anything we have that they may not know about, I sure as heck don't want to see it in round 1.
Play a game that will correct our issues, learn more about our players, and not expose a good play just to win this week. That'd be how I'd play it...
