Not ironic at all. He coached there prior. Has more than enough money for he and his family for generations. It is clear that his thing is helping young men become solid members of society and football is the vehicle he uses. When he left Virginia it was pretty clear that he believed he did not have the energy to accomplish this goal at that time.
Bronco is an odd duck, no doubt about it. But he is a fine football coach who has a different value set. Frankly, the older I get, the more I respect people who just do them. He wants to go back to New Mexico coach ball, and run his ranch. Go for it.
