There would have been players whop likely would have figured out their future by how the depth chart worked it's way out during spring ball. A guy like McKinley might have either been impressive and moved up the depth chart or may not have and self selected out as either a grad transfer to another school or just end his college football career. The lack of spring ball may have also limited his options for a transfer since other teams may have been in the same boat and thus limited his options for other schools. I would speculate that the decision has already been made and that he isn't being given a 5th year but either a) McKinley hasn't announced it yet or b) Kelly is waiting on the final decision re: Kevin Austin. My guess is if Austin is on the team then McKinley isn't. Or Kelly is waiting in decisions by other players re: medicals, transfers or grades to see what his scholarship count is before he can commit to McKinley.
Right now ND is +5 which means 5 current scholarships have to go. It is too easy just to say no to a 5th year for a guy who hasn't set himself apart from the crowd at WR ( there are 12 guys at WR) than it is to force someone off the team unwillingly ro perhaps take a scholarship away from former walk ons. The fact that school is "closed" is also backing up the announcements.
I would guess that 2 WRs, at least one LB, probably 2 DL and possibly a RB are in the mix.
