We know Castle may or may not reclass, but my first choice would be for any other 2023 targeted recruits with interest who might be candidates to reclass. In basketball order: Griffith, Estrada, Miranda, Ball, Bowen, Kante, Watson, Chapman, Coleman, ... (Bradshaw, the California kids, and some others I assume are more long shots, especially to enroll early) (I have no idea if any player is in academic position to reclass)
Assuming there are no candidates to pursue for next season from the 2023 class, I would hope to get a couple players that each possess at least 1 outstanding skill that could help the team situationally. Understanding at this point we are not legitimately recruiting guys with complete games.
1. A smaller fast PG who can handle pressure with the ball, defend similar players, and make FT's, (Karl Hobbs ish)
2. A 6'7ish wing with a defensive stopper reputation (ie a Lyman Depriest) for pressing full court defense + 1x1
Alternatively, a frontcourt depth piece examples (rim protector without offense) (earth bound power player)
