I wouldn’t on the defensive side of the ball. If I am an up and coming talent as a position coach I’d take the job in a second.
If you can imorove a D that performed poorly last year and the O still sputters and the new GM decides to can MM you would be in position for the HC spot at GB. If you improve the D and the O gets back to its usual, the Packers will make a deep run in the playoffs and other teams will start looking at you for their HC job.
