First of all, Brady was mostly excellent in this game. Yes, he made a few mistakes, but fortunately none resulted in points for the Seahawks. The number of absolutely brilliant plays by Brady far outweighed the mistakes.
I don't know why anyone thinks putting Brady under center would have worked. The Seahawks have a great run defense. We couldn't run effectively against them. The spread was our only hope in this game. And for the most part, Brady executed it extremely well.
The score was 23-10 with 9:21 left. The defense played very well against the run, but (as has been a problem for years) gave up multiple big pass plays at inopportune times near the end of the game.
This pass defense is a huge liability. When the game is on the line, you can almost bet they'll give up not just one bad play, but two or three. It's the second and third plays that we can't recover from.
The run game looked really good the last two weeks against nickel defenses. Unfortunately, it's not looking nearly as good against big fronts.
Once again, it seems to be the case that the Pats cannot win a game if the offense scores an average (or slightly below average) amount of points. This defense just isn't a defense that can win games on it's own. That's too bad, because the offense won't be able to win every game. Sometimes the defense has to be the hero. I'm afraid this defense will never pitch a shut out or anything close. You have to assume they will give up 24 points and have to design your offense to score at least that much. If we had a better defense, we could run a more conservative, run-heavy offense. Without that defense, though, I'm afraid we're still stuck living and dying by the pass.
