He is a great basketball coach, though it appears he may have some ethical concerns. It is hard to recruit when everyone knows the NCAA will come down with some punishments.
Unless he is found to have violated some law, I think he ends up back in coaching, somewhere that has nothing to lose. I remember when I was young and was talking with Coach Newton after Auburn hired Bob Davis, Coach Newton told me to the effect, " Auburn will be on probation within five yearss. When you are on bottom you have nothing to lose by taking chances, and when you are on top you cannot afford to take chances." The problem with Miller was, if the allegations are true, that he was near the top when he took the chances.
