My thoughts:
1. PLAY SOME DAMN MAN COVERAGE! I was foaming in the mouth shouting at my TV all game at how many times we kept our DBs spaced 10 inches from SF's receivers, leaving them wide open. Do what worked for us in 2010, that is playing some man coverage. Tramon Williams is healthy again, plus we might be getting House back for this week (and even if we don't, we still have Sam Shields, who can at least play better man-to-man than Bush, which brings me to my next point) so who's to say we don't have the personnel to do it?
2. GET DUBYA OUTTA THERE! Swap Bush for Hayward, Shields or even House if we get him back for this week (though if putting him in this game is gonna hamper his play down the road, I don't want him in because, as the last couple of years have taught us, it's the games at the end of the year that ultimately make or break a team, not the ones to start the season).
3. Run D (obviously).
4. Get pressure on Cutler. We had 4 sacks on Smith, who's to say we can't get to Cutler's piecework O-line?
5. Run the ball better. Play action. Start through the air, and then go to the ground game. As we saw in the DAL-NYG opening day game, you need the pass to set up the run game. Notice how, ever since Tony Romo decided to start slinging the ball through the air, the Cowboys finally had some success running the ball? We need to follow the same philosophy here.
