Looking at the Det-NE game a little closer, a few things popped out:

1) Detroit actually did a decent job moving the ball in the first half, when the game was still in doubt. Their drives stalled.
2) NE was even more pass heavy than the final statistics indicate, 10 of their 20 runs were in the 4th quarter.
3) Detroit did not get any sacks. I can't find information on hurries or QB hits to tell what sort of pressure Brady was under.
