Best I can say is this:
Would you leave a job that you like and are trying to build something and finally have the support of those around you…for a job that yes pays more, but you have no support from President, the people with “power/money” have conflicting visions of what they want for program, the money can’t promise support you need, expect or want to make things happen, you have people involved who don’t care about football or sports and only care about Medical/Law School and tue President is t even involved in the process of hiring maybe the 2nd or 3rd most powerful person on campus. The structure and setup is one to fail. Trust wasn’t there. So walking was best option for him. Maybe not others but for him it was best option
