I think you can think whatever about any coach but the problem remains in the administration's commitment. Lavin's problems were fixable and he shouldn't have been let go. When you make the move to Mullin you had to know there would be growing pains and they should have stepped in to bridge gaps instead of cut the cord. It's a bad look and it's why no one wanted to come here.
We all know the administration at St. John's is clueless and is hindering the success of the men's basketball program. However, I'm not quite sure what gaps the administration could have bridged gaps with Mullin.
Put yourself in their shoes. Mullin begins to lobby for the job before Steve Lavin is even released. Repole revealed this in his interview with Francesa. The administration understands there will be growing pains with Mullin and agree to invest heavily (by SJU standards) in his staff. They go out and pay Slice big bucks and convince him to leave his cushy job at Kentucky for St. John's.
Not long into his tenure, Mullin can't keep his two top assistants from hating each other to the point where they essentially can't work together anymore. Mullin chooses Matt over Slice leaving SJU to have to pay Slice a hundreds of thousands of dollars to not work there anymore.
Instead of Mullin going out and finding a competent replacement for Slice, he promotes his friend Mitch Richmond to that position. A guy who doesn't coach and doesn't recruit.
They guy Mullin chose over Slice then decides to leave for Nebraska leaving Mullin with Mitch Richmond and Greg St. Jean as his only assistants. The staff at this time have recruited a grand total of zero players between them.
Now, unless Mullin was begging the administration to let him go out and find a quality assistant to replace Matt and another one to replace Mitch and they refused I don't see what more they could have done. And it's fairly obvious that this is not what happened.
So Dave, let's say you're calling the shots at SJU in April of 2019. Your Head Coach is neither an competent tactician or recruiter. One of his Assistants is also neither a competent tactician and does zero recruiting that Mullin refuses to get rid of. The other Assistant is a hard working guy but is still learning and also has zero recruiting chops. If you're not cutting the cord with Mullin what do you do that will lead to success in the future for the basketball program?
