Regarding Fickell, I really just don't see him leaving Cincy for 3 reasons:
1. He has indicated in the past that his family wants to stay in the state of Ohio
2. He just got a contract extension earlier this year
3. He has already made the CFP in 2021 at Cincy, and with Cincy moving to the Big 12, he will continue to have a better chance of making the CFP there than in the BIG.
