If I were Jerry, I would hire two new QB coaches (bye Wade), since there is no limit on how many coaches you can hire. One to work with the starter and the other focused on grooming the backup(s). I would give Linehan total control of the offense and game management and keep JG as the motivator/figurehead, while lessening his overall game day involvement. I keep Pollack and Rod.
This let's Jerry spank JG, while keeping him as a figurehead. If JG doesn't like it, he is free to walk away from 5 million/year, which he won't get anywhere else. I would lay down the law early, maybe even this year if we are eliminated from the playoffs. Any pushback from JG, means Sean Payton marches in to take over...Which is why I want this done as early as possible.
