You can argue whether the upcoming game at the New York Giants is really a must win for the Dallas Cowboys. With the somewhat muddled picture throughout the NFC East, it would not be impossible for Dallas to lose that game and then recover in the next two or three weeks to go on to defend their division crown. But you cannot come up with much of an argument that the team is not doing everything in its power to win the game.
