You mean that he's already a long shot to qualify when he still has two full years of high school left? Unless he has pulled a Blutarski there must be time to get his grades in order, I would think?
If that were true, you would think the services would easily be able to confirm it and remove him from the commitment lists. While I can see why he MAY not end up part of the class, had his offer been pulled months ago when the rumors started, IMO he would not be listed as a commitment.
