If he is a smart man, and i have no reason to think he is not, I would ASSume he already has a short list of prospective replacements if he chooses to go that route. It is possible he is having folks discreetly reach out to gauge interest.
On the other hand, he might feel as though Bo's persona has improved enough to give him another year regardless of the win-loss record. Maybe he has already contacted Bo after Wisky and said some folks have to go. If you choose to stay (SE says he hopes he will) that will be the price. here is a list........I'll need to know your decision immediately after the Iowa game.....
Who knows.
