My point about the general I know was not necessarily about the specific case, but that it is sometimes tough to discern who will do well at a service academy and subsequently who will do well as an officer. And let's face it, few in each class will be blessed with the talent and luck to make general. Most will probably be pretty good company grade officers, but that's it. And there is no shame in that.
I've been around O-6 grads who talked about how much they loved their time at West Point, only to be reminded by their classmates that they hated every of it as a Cadet, but that time has softened their outlook. I've seen Cadets who needed a gentle push from a loved one to pick a service academy but then thrived once they arrived. I've seen others who only dreamed of West Point find upon their arrival that they made a big mistake. Ya never know.
