I think they're waiting for the season to end. It's not like we're the type of football program that could steal a good coach mid-season. I also think they wanted to give the interim coach a chance, but that hasn't worked out just yet. Our AD was a former lineman at MI, he wants a football guy and he has stated he wants an offensive line that attacks. The recently fired PP believed in "zone blocking", and I think our kids were all about zone and nothing about blocking.
I've heard the names of a few coordinators from the SEC mentioned, but no head coaches.
