If a small market school (KSU, ISU, OSU, BAYOR, ETC) has excellent assistant coaches, they will lose one or two a year. They can only hope to hire another up and coming assistant of equal but unproven quality. They cannot afford to pay the wages to keep them for 10 years like Iowa does. So the mark of a head coach in these schools is the assistant coaches that he is able to bring on board even if for a few seasons. If you do not believe, take a look at Snyder's coaching tree and you will. Call it Hayden Fry's tree if you want but the conclusion will be the same.
