My only thought on Doucoure is that there's no way for him to reclassify to 2017 right now, as there are no open scholarships. If asked directly, even if he were planning on reclassifying, he'd have to say he was joining the program for 2018... because the next question would be for Pikiell, asking who on the team right now will be leaving to open up a spot?
I'm "wait and see" on Doucoure's classification right now, until we hear about a transfer request. If someone gets released from their scholarship to transfer, and Doucoure still says he's a 2018, that'll settle it for me.
