Here's the only possible way we max out our scholarships. Tre and Bolden return, we sign Matthew Hurt and Kira Lewis. In this scenario:
Sr (4): Bolden, DeLaurier, White, Robinson
Jr (2): O'Connell, Goldwire
So (3): Jones, Baker, Lewis
Fr (4): Carey, Hurt (we're not signing Hurt and Watford, one or the other), Moore, Ellis
And even still, J-Rob's scholly could still go elsewhere. K has a history of not having an overly crowded lineup (I suspect he knows 13 highly-recruited players could lead to locker room frustrations and inevitable transfers). 1991 and 2017 are the only years where we've maxed out our scholarships on 13 players that were recruited.
