Who do you think runs the offense now. Even if Huff takes it over he has head coaching work to do as well, so who helps or who takes it over?
Personally, I don't think it will work that way. Huff will be the OC for the bowl game, Bartrum will work with OL and Tight Ends, Others shift as necessary.
On defense, I can see them moving someone around to fill in at LB coach, and let Danny Derricott work with the DBs.
Further, there are a lot of Analysts waiting for a chance to do some coaching. They'll probably get some mentoring/coaching chances during the next few weeks with the younger kids; more than usual.
I know nothing, but these are my speculations.
