I do think that's a fair argument.
There's really two good sides to this QB issue IMO.
The team wants to reinsert Romo because it believes he's the QB to win with now based on his experience and skill. If he's healthy, it's hard to argue against that based on what he has shown over the years and how he led this offense in 2014. No one can really say until we see him out there that he isn't the best QB for now.
Then, there's the fact that the team is riding high right now behind a rookie QB who isn't making many mistakes and has a 112 QB rating. How do you take that guy out of the lineup? How could you not leave him in until he starts playing like a rookie ... if that ever happens?
That's why I'm of the belief that you let Romo wait in the wings until the rookie in Prescott shows up. Quite frankly, Game 1 would have been one of those instances and the beginning of Game 2 would have been another one, so it isn't likely that everything is going to go smoothly for Prescott in every game.
