The barn has no good options.
If they fire the Rev, they are looking for a replacement in maybe the worst year ever to be looking for a coach.  If they don't fire him, they're keeping a guy who is clearly in over his head.
Rev made his entire reputation on (1) beating us twice in a row, and (2) openly flouting the NCAA rules that really did exist at the time. 
The first win against us was absolutely earned.  The second was a confluence of our mistakes, miracle plays and officials' mistakes on the OL downfield.  And we still had a chance at the end.
Freeze's recruiting tactics involved paying players and making no effort to hide it.  Now that that's legal, it's no longer an advantage over the opposition -- they're doing it too.
He has whined, thrown players under the bus, and proven that his ostensible expertise on offense and QB development is non-existent.
Bad manager.  Inept offensive coaching.  QB moves 9 weeks into the season that reek of desperation.  Blaming players.  Recruiting used to be easy when he was doing stuff nobody else was doing (at least not to the degree that he did.... I'm under no illusions that anybody in the top levels of college football was truly clean). 
Now, he has to sell his program in addition to write checks, and that's tough when you look like this.
But who do you get that represents an unquestioned upgrade?  Other candidates are signing extensions fast, have just been fired themselves, or have big risks attached -- namely never having been a head coach at this level....or not at all.
Like I said, the barn doesn't have any good options regarding the good Reverend.
