no, we have the tie breaker with the Giants, so if we tie them at 8-8 we go in so if NYG loses to the Vikings, they are eliminated

The Giants have to win out and hope we lose both games.

So (if we lose to Philly) we in fact want the Giants to beat the Vikings so that they play the Eagles for a meaningful game.

Consider this: if we lose Saturday, then Fox has both the Skins/Cowboys, and the NYG/Philly game at 1pm on Sunday the 3rd, and the division champ could rest on the outcome of both games with the following scenario:
Philly wins, they win the division at 8-8 with a better division record then the Skins
NYG win, Redskins win, Skins win the division at 8-8 with a better div record then NYG
NYG win, Redskins lose, NYG win the division at 8-8 with Skins and Philly both at 7-9

edit: actually we own the conf. percentage tiebreaker with the Giants if we tie them at 8-8
