We only have three realistic options when it comes to hiring a head coach. An assistant or coordinator from a program that is on our level or better, a retread head coach that didn't pan out at a higher level, or an up-and-coming coach from the lower divisions. Since joining FBS, we had Faust (retread from Notre Dame), Owens (a high school coach), Brookhart (coordinator at Pitt), Ianello (assistant at Notre Dame), and Bowden. None of them worked out how we had hoped.
We have never hired a head coach from a lower division program. And yet, that seems to be where the highest numbers of successful mid-major coaches come from. The kind that come in, put up big win totals, and then get hired away to a P5 program like we've seen so many times at the top MAC programs.
