This year's Eagle's offense is going to be unstoppable for one particularly important reason:
Watch all the preseason games and you'll see one common factor on almost every play.
LeSean McCoy is wide open. Because no one is defending him. They don't respect him. They're too busy blitzing Vick's and double covering Desean Jackson.
And you can complain about "Checkdown Charlies" all you want, but were not talking about Correll Buckhalter here. LeSean McCoy with the ball in open space is almost a guaranteed first down.
Defenses will either respect him and lay off the blitz or the Desean double coverages or they can eat these screen passes for Breakfast Lunch and dinner.
