I would say the Patriots offensive line was ineffective in stopping the NY defensive line from harrassing Brady. NY defense did their job well, and that's what stopped the Pats from running away with the game as so many predicted. I thought it was a great game. My wife won her football pool, it the pats would have scored one more touchdown in the last seconds, I would have won my companies pool.
The last time those to teams played, the Giants couldn't get a hand on Brady. The offensive line played well, and Brady would step up in the pocket to avoid the defensive ends.
This time, they got a big push up the middle, and that was the difference.
