It's always a question of whether, if you elect to replace someone, you'll end up better off, or worse. In the short run you are often worse off. That said, if someone simply isn't getting it done, they need to be replaced. Solich faced that situation in the past, and fired several defensive and offensive assistants, and ended up with a much improved staff. I would presume that if that is needed now, he will recognize the need.
Keep in mind that coaching continuity does have value, and is one of the reasons for expecting Ohio to continue to be near the top of the MAC.
Being near the top of the MAC is apparently not exactly where Frank wants to be. He wants us to go to the next level. My question has been -how do you get there? Get an IPF, recruit differently, hire different coaches, change conferences, schedule differently, lower your academic standards? He made the statement about not being where he wants us to be-how does he get us where he wants us to be? I'm just wondering if new coaches might be an answer. Continuity so you are losing the Big ones may not be the answer.
As far as the Nebraska changes, he was forced to by the admins if I recall. Not sure there is that much pressure here to win 10 or more games a year. It only got him to the end of the regular season the next year anyway. It's not his style, for sure.
