There's a misconception that the no-hudddle means no-run. That's absolutely false. The no huddle can be quick paced, no doubt, but it isn't devoid of running plays. In fact, our most effective running play of late has been the lead draw. That is a play that is tremendously effective against a defense that is playing pass.
I think that the no huddle is going to be deployed depending on situation. Whether it's a defensive mismatch that the offense wants to exploit or a situation where Romo sees that the defense is gassed or confused. Forcing the defense to either adjust on the fly or call a time out. The no-huddle doesn't even necessarily need to score points to be effective. Simply forcing a team to burn it's time outs also makes it effective. Tough to challenge a play when you're down to your last time out, down by ten, and 3:00 to go in the game. I think it will be a very effective tool for this team this season.
