Whether you are for the coaches(any of them) or not, the only way they leave TN in the foreseeable future is if one of the following occurs:
They unfortunetely pass away
They are involved in a scandal, which could take multiple down if they are involved or know about it.
----OR they get a job offer somewhere else.
This would be the most likely, but still a long shot.
Only valuable coach that I see drawing interest anywhere would be Is Shoops, and while he's known for his elite defenses I don't know if that indicates a possible HC position, or his desire.
The schools that would pay the amount we pay wouldnt offer CBJ anything. I know many here are in love with him due to a more positive performance than the recent few coaches here, but these other top schools are looking for championships, not just being better like we've grown to accept. And CBJ has hit his ceiling on the moving up the ladder on running teams.
