This is a LOCK! Against Arizona if you don't think Dallas is going to destroy them your nuts! Miami kept it close because they have a good defense. Arizona on the other hand are 25th ranked Pass Defense (Tony Romo field day), and 20th ranked Rush Defense giving up around 120 yards on the ground per game (DeMarco Murray field day). Also Dallas is going to be well rested since the game from Thanksgiving, almost like having a bye week.
Dallas rolls easily in this game.
