Maybe. I don't know that it's inevitable. Some coordinators, I think, are what you might call "mad scientist" types. They are great with Xs and Os, but don't really have the charisma to forge a bunch of players into a team. Moreover, they know it, and don't really aspire to a position that takes them away from what they love - designing plays and strategizing, and instead taking the role of manager and motivator. I'm hoping Daboll is that kind of guy.
