I would not take a QB in the first round and I will give some reasons why.
We have needs at other positions like WR and we still have a questionable situation at places like Saftey and some LB spots on defense. We also have questions with some of our O-Lineman for the future.
IF we had all of the positions covered like WR, LB, O-Line, Saftey and so on, covered as the idea that most of our backups at that position show so much promise that they could be starters on other teams and future starters for us...it might be different.
So at this point I don't see us taking a QB in the first round. That does not mean we could not take one on the first day if a good prospect fell to the say the third.
Now say 3-4 years from now maybe you consider it. Because you would probably be reaching the end of the current contract with Romo. He would be a little older and that would still give you a year or two to groom the QB.
But right now, in the First round...I would have to say no.
