My personal opinion is that they need to draft Cardale Jones in the 4th round or so for the future. They also need to bring in JFF, RG3 and keep Moore to battle it out for the backup QB position.
My biggest problem with this idea though is that JFF, RG3, and Moore are all QBs that need to be in a west coast style offense sort of like what Joe Montana used to run. Good shifty back, zone block, lots of QB movement and quick RAC WRs with primary short throws and deep threats when they start cheating up.
Unfortunately Garrett is of the -- needs a pocket QB -- style offense with a dominant running game. Romo is in more of the Brett Farve mold, and can utilize some of the timing throws and lots of the multi read stuff. Unfortunately for Dallas, those QB's are few and far between.
My reason for Cardale Jones is that he could come in an sit behind Romo for three to four years, and learn, but already has the physical tools to play really either style offense. He is big enough, and with a strong enough arm to play the timing style offense, but still have enough athleticism to play like a Cam Newton style offense as well.
With that said, I don't think Cardale Jones is a first rounder, so I think you draft the best defensive player available in the first round. I would probably draft the best defensive players available in the first three rounds. Then give me Cardale Jones and Jakeem Grant in the mid rounds. Give me the Matthews center from Texas A&M right after them.
My personal belief is that no matter what, you won't win a Superbowl with Jason Garrett anyway because he wants it his way instead of him adapting to do what is the best of the players he has. Adapt to the strengths of the players you have instead of the RKG way. Dallas hasn't had a lack of talent -- heck Christine Michael being the leading rusher in Minn at -3 degrees and in this game rushed for more yards than AP proves that to me. I just don't think Jason Garrett can utilize talent unless that talent is both what "he" wants and it fits "his" scheme to perfection.
