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.
I don't know. Most in demand coordinator candidates are looking for some stability.
I could see a guy getting a promotion saying the hell with it and taking the risk. Either internal (Perry, Whitt) or external position coach who has been waiting.
Bud Adams told me the franchise he admired the most was the Kansas City Chiefs. Then he asked for more hookers and blow.
