So you are including the 4th quarter?
And overtime. (Not sure he read the part where Nehalem said, "They contained the offense for almost 3/4s of the game.")
The Pats did move the ball well against Atlanta for the first 3 quarters. They just made three catastrophic and uncharacteristic errors:
1. The Blount fumble, as they were driving for a score.
2. The Brady pick-six, as they were driving for a score.
3. The Bennett holding on the play that nearly put the Pats in the end zone at the end of the first half.
Those three errors cost the Patriots minimum 9 points, and maximum 21 points. I believe they'd have scored a TD in the third situation, and a TD in one of the other two, meaning I think those three mistakes cost them 17 points. Moreover, they directly led to 7 points for Atlanta (the pick-six). That's a 24-point swing just in the first half. Instead of being down 21-3, the Pats should have been up 17-14.
Nevertheless...the Falcons DID make the stops they needed to in the first half. The Patriots DID make those mistakes. And so you could say that the Falcons defense DID limit the Patriots for the first half anyway. Then the floodgates opened up midway through the third period and the Pats went TD, FG, TD, TD, TD.
