Finish with at least the same record as the Eagles. If the Eagles finish 8-8, the Cowboys must finish at least 8-8 as well. If the Eagles finish 9-7, so must the Cowboys also - etc., etc. Of course, finishing at least one game better than everyone else in the division would be simplest and best, since it would hand the division title to the Cowboys outright, but given that the Eagles have an easier remaining schedule than the Cowboys, I would think that unlikely. Win two out of the remaining three NFC East games. This would assure the Cowboys of tiebreaker advantage over any division rival (even if the Cowboys lose to Philadelphia in the season finale), because the Cowboys would have a 5-1 division record while every other NFC East team could finish no better than 4-2. Things worth noting: If the Redskins beat the Eagles, then Philadelphia falls to 2-3 within the division. Then the Cowboys would only need to win one out of their remaining three division games to achieve guaranteed tiebreaker advantage over Philadelphia (4-2 division record vs. 3-3 division record ). The Cowboys would still hold tiebreaker advantage even if they lost to Philadlephia in the season finale. Because the Cowboys defeated the Eagles 17-3 earlier this season, this means that the Cowboys could fall to one full game behind the Eagles before the season finale and still control their own destiny (assuming the Redskins and Giants haven't caught up.) Even if, say, the Eagles are 8-7 and the Cowboys are 7-8, a simple win over the Eagles in the season finale would put both teams at 8-8 and hand the division title to the Cowboys because of the head-to-head tiebreaker.
