For example if I coach (1) the Raiders; (2) Tennessee; and (3) USC, jumping each after one year, even though each is arguably a step up in prestige, no one is going to believe me if I claim to be loyal.
Whereas, if I coach at a high Big 6 program for 20 years, then decide to coach a low level DI school because it was my alma mater, no one is going to be questioning my loyalty, despite the fact that I've moved to a lower prestige job.
