It is the traditional competing interest... if the coach (and/or the program) does great, we may lose the coach, or coaches. However, in the time it takes to get the required attention, the program builds, succeeds, and the dividends outweigh that potential loss. It always hurts a program to lose the head coach, but the other 12 associated benefits are generally held in check, up until and thru the acclimation of the next coach (if it is strictly due to the program's success).
That said, I don't see Bustle leaving any time soon. I do expect the program to build and he will be inching up the attention list. I really like what Bustle and his staff have been able to do. We have improved in many, many categories since his arrival. We want instant success, but slow determined success is much much better. And, that is what this football program is doing.
It is always great when one of your worries is "will we be so successful that we may lose our coach to a bigger program?" That is the kind of problem we need. Geaux Cajuns!!!
