The Eagles are in the better position sitting at 11-4 right now. The Eagles are in the #2 slot right now, and control their own destiny for that spot. If the Eagles win tomorrow, they are the #2 seed in the NFC, and get a first round bye. If they lose, the Cowboys win the NFC East, and the Eagles could end up dropping to as low as the #6 seed in the NFC playoffs, and possibly a 2nd straight trip to Dallas to play the Cowboys in the first round of the playoffs.
As for the game itself, both teams come in playing really good football. The Cowboys have won 2 straight and playing well, showing that they don't necessarily choke every December. The Eagles have won 6 straight, and their offense especially is clicking on all cylinders. On offense, the Eagles will need to really run the ball effectively, and give McNabb time to throw the ball. I think that is the key to the game for the Eagles... the offensive line needs to give McNabb time to throw the ball. If this happens, the offense can play as they want to, and McNabb will have time to find Jackson, Maclin, or Celek downfield.
On defense, I think the Eagles really need to get to Romo, and get pressure on him, and be in his face all game long. The Eagles first need to do a good job against the Cowboys rushing attack, and not let the Cowboys beat you on the ground. We also need to focus on shutting down Jason Witten. As we know, the Eagles struggle with opposing tight ends, and Witten is one of the best in the NFL, so that will be an important matchup for the Eagles.
It will be interesting to see what the Eagles game plan is, and how they come out of the gates. I think that getting a lead in this game is very important. We need to be able to play from ahead. The Eagles are the best first half team in the NFL, and best opening drive team in the NFL, so hopefully the Eagles will jump out to a quick lead.
