Unless Childress and Bevelll cooked up something good (#12 as ball carrier through motion or direct snap shenanigans) for Sunday, it will be a classic Brett v. the defense. As mentioned earlier, his propensity for audible, hurry-up and improvisation will mean that he will single-handedly determine plays that will be either season-prolonging or season-shortening.
I agree completely with posted suggestions that we should pass first then run. Predictability has stalled #28 all year. When Bevell and/or Childress fail to alter formations and tendencies, Peterson was left to run at many a brick wall. Defenses pretty much know every time he's running. Literally. If they can start running on 2nd down (regardless of the outcome on 1st down pass), they will create some unease for the Dallas defense.
I see #29 as being the key to the game; how often can he bail Brett out when the pressure comes....If he can come up with 7 catches for 80 yards and a touchdown, get ready to visit the Superdome.
But hey, I'm the guy that said Brett was finished after the Carolina loss. What do you think?
