There does come a time when nearly everyone goes. It happened when Harlen took the reins in GB, and pretty much so again, when Sherman took control. Murphy established his entire hierarchy as well. About the only person left from the past is Ball.
I expect a new President coming in will want to establish "his culture" within the organization, and since I believe he will be more business oriented than football, he'll possibly hire a VP for football operations who answers to him, and that person will hire everyone on down, after consultation with the new Prez.
Carrying people over from past administrations turns out badly in most cases I'm afraid. That was one of the problems that existed after Lombardi left GB. They kept trying to resurrect it all in his image, and the people doing it didn't understand the culture changes that were needed to make GB a better option than it was, for a lot of the top free agents in the game.
A prime example would be the Ted Hendricks situation. He played one year in GB, on a trade, because of contract obligations, and told them straight out he was gone when the season was over, and he was. Not even an exit interview, straight out to California and the Raiders. An old comment we'd make in the military about things happening we didn't like. "Embrace the suck!"
