First of all, Atlanta has now become known for their Red Zone problems. They can move the ball as efficiently as anyone between the 20's. But in the Red Zone they just can't punch it in for a TD. And this year is looking just the same (small sample for sure).
Second, both Defenses played very well. They simply were the best units on the field for both sides of the ball.
Third, as for Philly's offense: they are missing their starting QB and best playmaking WR. Foles has always been up and down. He was down last night.
Fourth, there was a zillion penalties called last night that simply destroyed the flow of the game. Not blaming the officials; but there were a couple of phantom Oline holding calls and phantom PIs that had significant impact.
