If he went to another 1A school he would have to sit out next year and only get 1 year to play. Between that, 1AA, and backing up at
OSU I'd choose
OSU. If he does leave I would expect it would be to 1AA because there is no use having to sit out another year. If he was going to go 1A it would have been smart to get out before this season started so that he could play next year.
