Crazy part to me is that we could actually lose to the Cowboys and still win the division. Cowboys lose out except beat the Eagles, Eagles win out except lose to the Cowboys and sadly enough we are in at 8-8. Cowboys would have to lose to the Redskins, which seems unlikely, but they did lose to the Jets, so it is possible (and they could say the same about us losing the Dolphins).
Eagles hold the tie breaker if we beat the Cowboys. We have a better record against common opponents. Exception would be if we lose a division game and Cowboys lose to Rams, but beat Redskins, then they would win based on division record.
Either way whoever fails to lose the division (that is the right way to phrase it) is going to be a prohibitive home underdog in the first round.
