Wow, this seems overstating it. At least one stays, and becomes the heir apparent with any ounce of good fortune:

If Murphy chooses Ball, whose primary duties are negotiating contracts but who has been studying personnel evaluation under Thompson, he almost certainly would lose all three personnel men, a source familiar with the Packers' front office said.

His hiring would signal to them that they had no chance of becoming general manager in Green Bay and would be better off elsewhere.
