I would already take Dak over Romo because he isn't ever going to piss away games in the clutch with retarded decisions.
He made plenty of very bad decisions last year but I agree that there is a maturity (some may call it conservative nature) to Prescott that Romo never really had until he was in the league for about 10 years. The flip side of that is that Prescott doesn't make as many high risk/high reward plays but I'm ok with that.
Often times teams will put too much on an elite talent at QB, neglect parts of the roster, and fail to build a fundamentally sound football team because the elite QB provides a crutch. Whether that's conscious or subconscious nobody knows but I think it's the reality often times.
I've also always believed that it's better to have a young QB who is cautious by nature and who will grow into learning when and where to pick his spots as he matures rather than a big-time risk taker who has to learn how to dial it back. The risk taker will always have that impulse to take risks in that split second moment, the more cautious personality who learns when to take shots will be more cerebral with their decision making.
That's how Brady developed honestly, probably Wilson also.
