Over the past three weeks, the Cowboys have managed to end the Saints’ perfect season and hold the Redskins and Eagles to a combined zero points of offense. They’re the hottest team in the NFC right now and will play a Philadelphia team on Saturday that they’ve already beaten not once, but twice this season.

But the postseason has not been kind to the Cowboys over the past decade. In 2003, the Bill Parcells-led Cowboys were shellacked 29-10 by the Panthers in the Wild Card round. In 2006, Tony Romo had, uh, some trouble with a field goal snap and in 2007, the ‘Boys were bounced out of the Divisional Round at home by the eventual Super Bowl champion Giants.

Yes, the Cowboys have beaten the Eagles twice this season and yes, their defense is playing lights out. But these are the Wade Phillips-led Cowboys were talking about here: Nothing is a guarantee and nothing should be assumed.

Dallas clearly matches up very well with Philadelphia. Their front seven has been able to shut down the running game and thus, Phillips has been able to amp up the pressure with edge-rusher DeMarcus Ware. Donovan McNabb hasn’t had a lot of time to throw the ball, which limits the Eagles’ ability to strike for big plays like they have all season.

Playmaker DeSean Jackson has 63 receptions for 1,167 yards and nine touchdowns this year. But in two games against the Cowboys, he has just five catches for 76 yards and no touchdowns. That means Dallas has been able to contain Philadelphia’s most dangerous offensive weapon.

That said, the Cowboys have found ways to lose before, so why should anyone trust them now? They’ve been a team under Phillips that hasn’t been able to get out of its own way, so would anyone be surprised to see Philadelphia walk into Jerry Jones’ brand new stadium and steal a win? Doubtful.

Dallas needs to rely on its defense to win on Saturday and limit mistakes offensively. If they can do that, then they shouldn’t have issues beating an Eagles team that has fought their own postseason demons in the past.

Should make for an entertaining Saturday night.
