This is actually my biggest concern and I would honestly trust Romo more to develop a young QB than either dipshit Garrett or Wilson. Especially a guy like Wentz who I think his biggest weaknesses are that his footwork can sometimes get stagnant in the pocket and he sometimes locks on to WR's. Romo's footwork in the pocket and ability to go through his progressions are arguably two of his biggest strengths.
Plus, Rodgers was drafted by one coaching staff in 2005 and then McCarthy was brought on in 2006. I don't think Garrett will be around in 2017 unless we make the playoffs next year so there is a half decent chance that he's fired after next season and a new staff is brought in.
