I would be surprised if quite a few didn't go, but this may depend on how much involved they were when Jones was manager.
If Jones ruled with an iron fist and their advice oftn went ignored(not unlikely given some suspect decisions) then perhaps the new regime may decide they could be useful, well some of them.
Then again perhaps that was seen as wa weaknes and they will be turfed out anyway.
The fact they are still there gives some of them hope though.
