I don't know about that.. it is a thought, of course. But Moos made his "get us six wins" remarks at the beginning of the season, then walked it back as the losses piled up. His new spiel became about how much time this is going to take rebuilding the program; which indeed is what he said about the timing of this contract extension. He said he was going to do it anyway, but doing it now would be a statement as to confidence in Frost, etc.
I also get the impression that he's basically doubling down on this as a statement to his bosses, who approved the extension (how reluctantly, or after how much lobbying by Moos, we don't know).
