In all seriousness- when Romo retires he should instantly be installed as QB coach or OC. He probably won't want to with his two sons growing up so fast.
Romo is a football savant, and when he says he will find the next great DC QB, I believe him... I believe he wants this franchise to win big, and would never consider another team for employment due to the attempted career assassination by the media and NFL fans.
If this team can do it's advance scouting homework, and can find the correct personality and skillet- there's every reason to believe Romo could turn said player into a SB caliber QB.
It's funny: I was watching Manziel the other night and felt if his ego wasn't so large, he was the kind of player that Tony could turn into an elite QB via the repetition of mechanics and identification of scheme that Romo committed himself to under David Lee's tutelage.
It will be interesting what direction Tony takes post retirement. He's completely unique and if we can keep him in our organization- that would be a huge, huge win for all of us.
