The first key for the Cowboys is, stop LeSean McCoy. There's been a lot of talk all week about who will play quarterback for the Eagles, will it be Michael Vick or Nick Foles. The Cowboys biggest concern needs to be LeSean McCoy, the Eagles' running back, who's leading the league with 630 yards rushing, and when he catches the ball he averages 16 yards. They've got to make sure they tackle McCoy when he's in space.
The second key is to "score 30 something." With the number of injuries the Cowboys are nursing on that defensive line you've got to be able to score points to win this game.
The third key is the other guys. The Cowboys need continued contribution from the guys you don't know much about. Guys like Joseph Randle. Guys like Drake Nevis, Dwayne Harris, and Cole Beasley. They must step up if the Cowboys are going to go to Philadelphia and win thier first road game of the season.
