The Packers are heading in the opposite direction. The Pack had a terrific preseason—after which many had them as a Super Bowl contender—but now the Packers stand at 4-4, and just recently lost to the winless Tampa Bay Buccaneers.
The Packers are better than they played against the Bucs, so the Cowboys cannot go through the motions and expect a victory, especially at Lambeau.
Here are the Cowboys keys to victory over the Packers.
Pressure Aaron Rodgers
The Packers quarterback is a good, young quarterback. His offensive line has been porous at best, as he has been sacked 37 times.
But not all of it has been on the big boys up front. Rodgers has a tendency to hold onto the ball too long. He has the NFL's best QB rating against the blitz, but some of that has to do with taking sacks instead of throwing the ball away, thereby increasing his rating, but ultimately killing his team.
Repeat the defensive gameplan from the Eagles game
The Cowboys and Eagles had the same amount of sacks last week, but the difference was the Cowboys got pressure with their front four (when Ware rushes they are in a 4-3 as opposed to their base 3-4), while the Eagles blitzed on almost every down.
This allowed the Cowboys to deploy bracket coverage over the top on the Eagles speedy wide receivers, and allowed the linebackers to cover the flats and the middle of the field. This took away most of the Eagles options in the passing game.
The Packers have some great wide receivers in Donald Drivers and Greg Jennings, and depth at the position with Jordy Nelson and James Jones.
If Dallas can get pressure up front without having to blitz, the Cowboys secondary should be able to handle the Packers wide receivers and eliminate the big plays down the field.
Establish the run early with Felix Jones and Tashard Choice
Did you see how much of a monster Marion Barber III was at the end of the Eagles game? That is the strength that horse brings to the table, and that is where they should utilize him.
The Cowboys should start the game off with a heavy dosage of Jones and Choice, who see the field better than Barber. Early in games, there are a lot of times Barber misses the holes that Jones and Choice almost always hit. Give the young guys a chance to get up on the Packers early, and then let Barber maul them at the end.
Take advantage of Aaron Kampman injury
The Packers linebacker will be out with a concussion, and rookie Brad Jones will take his place. When Jones is in there, the Cowboys should exploit the mismatch with tights ends Jason Witten and Martellus Bennett in the passing game. If the Packers try to counter that with a nickle defense, the Cowboys can crush them with Barber, Jones and Choice in the running game.
Don't get complacent
The Packers offense has a ton of firepower, especially in the passing game.
In the two games against the Minnesota Vikings, the Packers were on the verge of getting blown out. The Packers had incredible comebacks in both games, and would have won, if not for a Hall of Famer named Brett Favre.
If the Cowboys get up early, they need to keep the pedal to the metal until the game is over.
