This. Cant be mad at the staff for losing him when he's buried on depth chart. Can't be mad at kid leaving cuz he wants to start (and could elsewhere prob). Portal giveth, portal taketh away.
Reality of the portal (and NIL, but not sure applies here). Kids want to start, realize they have no shot, they will transfer to lower tier school that has a need. We benefit from it too. Is what it is. Best of luck to him
