It really would be a great move for us. The biggest weakness Jason has had as the OC is situational game & time management, no answer to the blitz in big games, problems running the ball and scoring inside the redzone. Some of these problems are personnel problems mainly on the offensive line and some are based on the offensive "Air Coryell" philospohy with these particular players. The Air Coryell vertical attack is not very friendly to Romo with this line...especially against the blitz. They plays take a long time to develop and zone blitzes force Tony in turnovers. Callahan fixes these problems. First Jason will be able to fully immerse himself in the game management process on both sides of the ball. Callahan will continue to run the Cowboys Air Coryell "number based" system and add some of his WCO plays for Tony. This is important, because we don't have to learn a new offense just add new plays. Callahan can install WCO plays, assign them a number with Garrett and make the offense more Romo friendly. When we're not in shotgun, more three step drops and get rid of it, the short passes should open up more running lanes and deep balls plus take some pressure of Romo and the "OL". If we can get the running game going we have the play action/boot rollouts for Romo similar to how Rich Gannon was used and how and Aaron Rodgers is used today. It allows them to make more plays with their feet and and can punish the blitz. Both systems are timing based and I think we can thrive with Dez and Romo now on the same page. Romo may need to make some adjustments from reading the deep man first to going through more progressions and dumping it off if nothing is open. I think we can bring that along slowly and he can do it, he's a great student. Really what we'd be doing is moving from Coryell to a hybrid Coryell/Walsh WCO using the same number system we are using now. At the end of the day Jason will be better, Tony will be better and we can focus the main philisophical difference on the defensive side of the ball. I love the idea and think this is where we're heading.
