College basketball is a business. The players are at the university 4 years and move on.
Loyalty should be a two way street but it is not.
Don Donoher was very loyal and he was fired. As I understand, Ron Jirsa, Billy Schmidt and Tom Ostrom applied for the head coach position and were not hired. I did not see much loyalty to them. UD wanted a better opportunity. That is just part of the business.
I don’t fault people for finding better opportunities, players, coaches and administrations.
