If Romo is not considered an elite QB after an almost MVP season last season-- then he's right on the cusp. Call him a "great" QB if that makes you feel better
Not having adequate depth at QB ABSOLUTELY killed us this year. Brandon Weeden?! They gambled that Romo could stay upright behind "the greatest OL in the NFL" and they got burnt. With a solid backup (Orton's caliber)-- we would not have lost 7 straight games. The offense failed to score a single TD in 2 games! To say that we wouldn't have been better with additional depth at QB is off base IMO.
WR depth is less of an issue-- but still one that hurt us primarily b/c the front office over-estimated the talent on the roster. Beasley, Williams, and Street failed to beat one on one coverage and that only limited the offense that much more. Adding a quality vet WR in free agency would have helped-- a guy like James Jones was picked up by GB and has been helping them out all year long even with their #1 Jordy Nelson on the shelf.
I don't see major changes next year either. Unless this team just absolutely quits-- but I don't think that will happen. I think JJ will keep Garret, Linehan, and Marinelli-- but Bisaccia and some of the assistants like Jerome Henderson may get the boot.
IMO-- Romo should stay in the system he's comfortable with. Either he and JG win big-- or we clean house in 2-3 years when Romo retires.
