Smart, young Qb's have done pretty well in recent history in the NFL. The ones that seem to fail early are the ones who are thrust into a bad situation.
Let's not forget, muhc like Rivers, Romo has had plenty of time to learn. He might be inexperienced in terms of game play, but he has been around here longer than even Bledsoe. The defense, though bad last night, have been quite good this year. The running game has been there, besides last night. The weapons have been there all year, and actually looked like they were being used by Romo.
Romo is in a perfect situation to succeed, from a personel stand point on our team.
The schedule doesn't favor him. But I think overall, the team is good enough to help him get his feet under him.
Parcells will stress keeping Turn Overs to a minimum, and paying smart. I think the defense might play with some energy knowing the QB is capable of opening up the O a bit.
Of course this is all wishful thinking, but Romo could very well suceed early, like we have seen with a number of other young QB's.
