yea, factoring in whether your team has already won a SB, indicates you're making an emotional decision based on Tony Romo. If you are doing what's best for the franchise long term, not winning a SB with this team should not effect your decision.
I would conceded that our best chance of winning a SB next year or the year after, is to not draft a QB in round 1, but I think that is extremely short sighted. What would you say our chance is next year if we hit on the #4 pick? 10%? Probably less. Assuming we have a good year and fall just short of winning a SB, do you think our chance goes up? Maybe a little, but not much. But after that, Romo will be 38, so barring us getting a Peyton Manning or Drew Brees like player in free agency, that number dives towards 0%.
If we draft a QB and hit on that pick, then yes, our chance of winning a SB will not be as great the next year or two, but it will be significantly higher the next 3+ years.
I know this was not directed at me, but I can tell you I have never advocated drafting a QB in the first round or an early round, because like you I believed our best chance of winning was to surround Romo with the talent and we never had a high pick to spend on a QB I wanted. I even thought taking Andy Dalton in round 2, if he were available in 2011, would have been a waste considering Romo's age. But at 36, this just isn't the case.
