I'm a Dak fan as much as anyone, I'm also a big Romo fan, but for this to happen Dak is going to have to play the first 8 games at an MVP level. If we are undefeated, Dak is has the highest QB rating in the league and we're just a offensive juggarnaut then the discussion will come up. But we most likely won't be and not because of Dak but we wouldn't be with Romo because of the defense. Dak would have to play better than Manning and Brady for it to even be an issue. Most people in Dallas or outside of Dallas would agree that Romo is one of the top QB's in the league. To unseat him Dak will have to be the best QB in the league, numbers wise when Romo is ready to come back.
If we go 4-4 or 5-3, or even 6-2 then we know we got our guy for the future, because even going 500 for a rookie QB is pretty good, cuz he's learning on the fly.
A completely healthy Romo gives us the best chance to win this year.
Now I will say that Dak may be that special player and be our franchise guy. But Romo spoiled us by taking over for Bledsoe and playing at a pro bowl level. But Romo sat and learned for 4 years. But everyone is saying Dak is mature beyond his years so hopefully it won't take him four years to be able to play at a pro bowl level. But this season if he can keep us in the hunt until Romo comes back then he has above and beyond played above expectations and is our guy for the future.
