It's also makes you look really stupid if you come out and say you're 1000% behind your coach and he then goes out and loses to a mediocre FCS team who doesn't complete a pass.
As I said earlier, unless you are absolutely sticking with the guy no matter what, you stay quiet. If we would have lost the last two games, it's likely Bo would have been out. Now, if we win Friday, I would be shocked if he isn't back. But when it's that close, you look really bad if you say one thing then end up having to do the opposite.
