Garrett and Linehan do a lot of what another QB coach would do.
Then why isn't Scott Linehan doubling as the QB coach?
Rod Marinelli didn't stop coaching the DL when he was promoted to defensive coordinator.
And wouldn't their experience as former QBs and offensive coaches make them very demanding of that position coach?
Wade Wilson is here because he is practically a lifer working for Jerry Jones.
If he were fired tomorrow, no team would fall over themselves to acquire his services to develop a quarterback.
But Wilson would get another job?
Or would he go to work for one of Jerry's other businesses?
Jerry is certainly loyal to his guys, but Wilson wouldn't be here if Jason Garrett wanted someone else who came available.
Jerry pushed Bill Callahan into the play calling role against Garrett's wishes in 2013 and it became a difficult situation.
I see no reason to believe Wilson is still here because of Jerry's unsubstantiated feelings for the coach.
If Garrett didn't want Wilson, he'd be somewhere else.
That doesn't mean Wilson is a great QB coach, but it says he's doing something right in order to keep the job, IMO.
The head coach and offensive coordinator are both former QBs, I expect they set a very high standard for the QB coach to meet.
