The more I think about it, The Cowboys made the right move by skipping Johnny and picking up the guard from Notre Dame.
That's the third first round offensive lineman they've picked up in the past 4 years and the other 2 have been pretty damn good so far.
So basically you have 3 top tier lineman all under 24 years old and if Romo isn't back there having to pull his "jedi pull a play out of his ass" routine and has time to throw then he can be pretty damn good. One of in the best in the league when he doesn't have to force plays, IMO.
The Cowboys defense is still garbage so it will still likely result in mediocrity next year but I'll take that upgraded line and Romo over Manziel and all the potential headaches he presents.
