Over the past season and a half, the Cowboys are 11-1 at home. However, they are 6-6 on the road.
Last season the Cowboys were 2-2 on the road against teams that made the playoffs that season.
This season, the Cowboys have played 4 games on the road so far. They crushed the Giants, lost big to the next 2, to the Cardinals and 49ers, and got past the Chargers by a field goal. Currently, it looks as if the 49ers will be the only one of those four teams to make the playoffs.
Just like the Cowboys, the Eagles are undefeated at home with a 3-0 record. The Eagles know how important this game is for the Cowboys as well as Eagles fans.
If the Cowboys were to win this game then it would signal a turning point in their season.
The Cowboys don't need this game to make the playoffs but I think they would need this game if they are to make a significant impact during the playoffs. In that respect it is a must win game. However, the probability of a win, in my estimation, is about 47% to the Eagles 53%. This game is going to be very tough to win and absolutely needs the stars to shine.
