I'll stick to my same point that Romo seems like he needs plenty of time for things to come open. Rodgers is the same way, so in Rothelisberger is this way also. They rarely go with the first read unless it's just no time for anything else, or it's wide open. So because these guys can move around in the pocket and buy time, this is what they do. Great defenses don't give you that time. Now, teams that tried to sit back and let 4 men get to Romo, that's not going to work even if they didn't have a great offensive line, because of Romo's escape abilities. So what Washington did was just bring the house. They brought the house, so there's no time to wait for things to come open, no place to escape to.
Sometimes, you have to have a plan, know where you're going to go with the ball and let it fly. If I'm a team going against Romo, I bring blitzes from everywhere, different places different times, just like what Zona and Washington did. You're not going to get to him with a 4 or 5 man rush. So I said all that to say this, the biggest blessing so far to happen to Romo is this line, and this running game.
