He didn't get close to a HC job since leaving Denver because most clubs were hesitant to hire him based on the debacle of his stint there: Mismanaging the team, ethical issues with video spying, treating players like HS kids, creating a toxic atmosphere and a divided locker room w/ his ever present spies and his "You're with me or you're against me attitude"
Now, with this on top of it, particularly shafting the ACs who bought his sales pitch and then had the rug pulled out from under them, he will never see a HC job outside of NE IMO.
