QB job is easy money.
Teach QB to keep eyes on the play clock... Help him with cadence... and calling audibles... how to count 11 players before a snap.... and other basic reminders like.... step into the pocket, get elbow above shoulder, hips squared to receiver, throw off front foot, lead the receiver,...... And lots of encouragement plus help with playbook as needed.
As long as he does that, he's good to go.
What we don't need is a QB coach that f#&%s with QB's head like a golf instructor can do. Or tells them they must read Immanuel Kent and Bill Walsh on weeknights.
In other words, I am not worried here.
