Does West Point pay players, beyond the normal cadet stipend? If not, I suppose it's understandable why he'd leave the Academy but not really dedicated to a military career.
No idea on this guys situation but my understanding with the transfer portal is if they transfer before their senior year they don’t have to fulfill the mandatory service requirement afterward. I remember that being part of the reason Paul Skenes transferred from Air Force. Feel like this is common for anyone at the academies who may have a chance at a pro sports career, they don’t necessarily want to delay it for military service.
David Robinson was a rare breed in that regard.
