You were saying, the head coach decides everything that happens and has absolute control and can change anything he wants at anytime.
I don?t think this coaching staff was his choice to begin with so it may not be just that easy to step in a head coaching job with a OC that?s already in place and a DC he?s never worked with and control every aspect of offense and defense.
When a HC is hired and told to keep certain coaches it is a very difficult position especially if the assistant are tight with the higher up administration. Good luck and a no win situation.
