Just pure opinion here as well but I would think Miller would be least likely seeing that he is a year further removed from high school than the other 2 and has already spent a year developing his game at prep school.
Looking at the roster if everyone returns, throw in the 3 transfers, Russell, and Adebutu who is red shirting this year we would actually be 15 deep not counting Broussard and Aucoin. Odds are simply that at least one of those 15 won't be around next year, and of course there could be an injury too but someone is either going to have to choose to sit or be buried deep on the bench.
