Why should the staff have any interest in him ever again? That is like trying to bug an ex-girlfriend to like you again. If she comes back, then you can start talking about a mending a relationship. This isn't on K-State to have to put in effort on someone who has no interest. Sounds like a huge waste of time. If he enters the portal 2-3 years from now and wants to come home, then K-State can reach out one time and see if he has interest. Otherwise...have a good life.
