If he goes, he goes. If he stays, he stays. It’s what happens when you pull in highly rated recruits. There’s no reason for him not to test the waters and get valuable feedback.
IMO, he’s definitely staying. He’s a great player with great athleticism but doesn’t have the handles and vision to play point at that level and doesn’t have the size or shot consistency, especially driving to the bucket, to play the two. He needs to develop his traditional PG skills another year or two and he’ll be a guaranteed first rounder.
