I would absolutely trade Romo to the Cardinals for two #1's and a #2 (and they could absolutely get that). Yes, he is a franchise quarterback, but this team is going to choke to death if doesn't build get him to something significantly cap friendly for the next few years.
I would draft Warmack (even trade down from Arizona's #7), Richardson, Cyprien, Terron Armstead and the best available QB in the 3rd.
Then I'd ride into 2013 with a dominant defense, young but promising offensive line and try and "Trent Dilfer" a season with Kyle Orton.
Then, with two #1's in tow in a killer QB 2014 Draft, I'd go after the best QB there is. And, without Romo's huge contract there is room to re-sign Bryant, Carter, Lee, etc.
