IMO Father Harrington has done an excellent job in many areas of building the university. One area he has been horrible with is basketball. He needs to stay out of it and he needs to keep Louie out of it.
That's the problem. If the President is doing a great job overall, how can you remove him from only one aspect? Who has authority to do that? The answer and decision has to come from within himself, which I doubt will ever occur.
Technically the board of directors are above him. Unfortunately it is an unwritten rule with BOD's all across the country to stay out of coaching searches.
I met with the board a few times while I was a student, and they seemed pretty eager to get the students take on things. I don't know who remains from that board, but I'm sure the students could convince them to put some pressure on Father Harrington to stay out.
After all, him interfering with a coaching hire is not his job and how much different is that than him interfering with a professor's class?
