There are currently 4-5 D1 openings that are unfilled. Wouldn't you be shocked to see him at Tulane, Bowling Green, East Carolina or somewhere else? He may very well get the opportunity to be a HC, but I can't think of many unsuccessful P5 coaches getting D1 offers immediately following their termination.
As for the DC gig, I admittedly typed that while forgetting about the Cubit situation. If that doesn't open up, I agree that he may very well be a DC somewhere next year, but I don't see it at a P5 School. I hope I am wrong.
