You make a very compelling case here for Caslen being entirely the wrong person for this job. When Caslen took this job he did so under the guise of doing what is in the best interest of the University. You've just indicated that he may not have done so for personal reasons. In other words, he put his own personal feelings above the University he gets handsomely paid to represent. No different from a city mayor who refuses to help anyone who he feels didn't vote for him. If you don't have the maturity and character to act in the best interest of your employer, personal feelings be damned, you are ill suited to the job. Caslen has both the moral & ethical obligation to act in the best interest of this University. Darla Moore has no such obligation, she also had no obligation at all to become the largest donor in the school's history, but she did it anyway.
If your premise is correct, and this is how he leads, he should be fired yesterday before he makes another self-interested decision that hurts the school.
