Watching the film earlier in the week.. I asked myself the same thing and it opened a question from last season on in game adjustments I had then.
At times last season, cough MN, I was disappointed in the lack of adjusting to the offense.
But then I watched Vick run around linebacker after linebacker and thought maybe base or a spy backer isn't the correct idea with a talent as only Vick is.. he is just doing to run past them anyway.
I think, in watching, Dom was trying to keep as much depth with his defense as he could while still applying pressure.. with depth he was going to give up yards but not home runs and playing with multiple score lead he figured that they wouldn't have enough time to come all the way back.. and believing we would continue to score.
Listening to Moss on the sidelines in "Replay".. you could tell they were worried about the "explosive" homerun type of plays more so than chunks of yards here or there.
Additionally, while I agree Vick is a average to slightly below average passer.. Mike Vick is going to take hold of that Eagles offense and if he plays at the level of this past week.. may make the Eagles one hell of a dangerous offensive team.. piss on the Cowboys.. I think the Eagles in that case become the division winner in the East.
