The Eagles are doing their homework of researching the Dallas Cowboys and they’re able to get info from somebody who knows the inner workings of the Dallas defense.
Andy Reid said the Birds coaches have made it a point to question former Dallas defensive coordinator and current Eagles defensive assistant, Brian Stewart.
Stewart ran a Cowboys defense that dominated the league a couple of years ago and sent multiple players to the Pro Bowl.  When the defense and the team had some problems last year, he was designated the scapegoat and let go.
He knows their personnel and he knows their defensive schemes.  Reid said Philips has changed some things up, but they still do a lot of the same things they did when Stewart was there. 
The Cowboys are blitzing alot more now than they were when Stewart was the defensive coordinator.
The fact that Stewart is spilling his guts to the Eagles coaching staff will make the Cowboys change some of their calls and tendencies, but a good teams doesn’t change their habits but so much because they’ll wind up getting away from what they do well.
From my knowledge of Phillips, he likes to blitz without putting his secondary in total man to man coverage without any help.¬† I would expect them to come after McNabb with some zone blitzes because you’re not risking the big play.
Phillips will be apprehensive about getting beat for big plays after seeing the Eagles on tape.
The Birds must be able to throw the ball underneath to Brent Celek, Leonard Weaver, Brian Westbrook and LeSean McCoy, so that they make the Cowboys pay for keeping safeties deep and giving them the underneath throws.
They can’t go into this game with the mentality that they’re going to throw deep even if it’s not there.
One of the keys to their season will be developing the ability to adjust to the other team’s game plan.
If the deep throws are there they must take them.¬† On the other hand, if they’re not there they must throw the ball underneath and be patient.
This is one of the areas I want to see McNabb step up and take leadership.¬† He’s got to make the adjustments even if the coaches on the sideline aren’t doing it.
