Looking down the coaching roster the only guys likely to take a hit this year are Clements or Gray. I think it HIGHLY unlikely that both will go - that's just too much change.
As for the other coaches, think about it:
Offense
Wyche will probably remain QBs as a result of his health.
McNally has a mulligan to work with the OL again - largely down to the fact that MW proved a total bust and Peters looks to be coming along very well under his tutelage.
Miller (TEs) - likely candidate for a reshuffle as TEs have been underwhelming. I really don't see the need to shuffle the pack this low.
Studesville, Tolbert, Verducci - unlikely to be reshuffled also.
Defense
Krumrie - loved by everyone, depsite the DL basically sucking. Can't motivate Big Sam and the DL has been woeful this year. It's too much of a reach to see him promoted or sacked.
Szabo - old, he could retire - but DBs seem to be performing well under him.
Lester - what does he do???? I think Chucks time could be up. Sacrificial lamb maybe - not a huge loss, he's ginger
Blackmon - no way we lose this guy.
So no way there is wholesale change even if the OC or DC is 'rotated'.
IMO - the coaching roster only changes if Gray gets his HC shot.
