Regarding Barnett and character concerns, I think a good litmus test is to ask yourself what your initial reaction would be if a rival school hired him. Granted, the man can coach, but I wouldn't be completely comfortable with it. Winning would put everyone on board, but any off the field problems would make a segment of the fan base go nuts.
We had a divided fan base when McCarney was let go. Now that Chizik has kicked Iowa State in its collective crotch, we're very united. Hiring Gary Barnett would divide us again just like that.
I still think we're getting a surprise hire. Maybe I'm naive, but I'm not closing the door on Gary Patterson.
