Why should it be presumed that we will have to go through an entire rebuild? Before I get crushed with “because that’s what always happens here” this team is balanced for the next 5-6 years which is completely different than any other coach in last 15 years.
If Mullin does not succeed, which I don’t believe he will, the next hire will have more players to start with, which is what normally happens in cbb. Will there be defections and recruits not coming, of course but at least that coach will have a base to work with, and hopefully is a competent coach, currently somewhere with experience.
