I think win or lose we probably need philly to win.
IMO that's because we still play against philly on Christmas to go up on them again.
If NYG win and we lose, then we are tied with them, which is advantage NYG, then they have a chance to take the outright lead on us depending on what happens.
I think that it benefits us more for philly to win. Then if we win out the Giants will have already been too far to catch up, and we would have taken care of Philly on Christmas to keep them 2 back.
I guess i could be wrong, or forgetting something, but IMO it seems like Philly winning is the best scenario.
