I know exactly where Raul is coming from, and agree with him, but you're not fully wrong either. Duke and UNC have a specific system, and some players adapt with it or some fail. Nolan Smith was one of the most nastiest Oak Hill players ever. Youtube him. His game completely changed when he went to Duke, and struggled until his Junior year. Senior year, Killa Ky was there. Make this short and sweet, certain kids game doesn't fit Kansas. You could see a kid play, and say he is not UK material. Jayson Tatum style of play at Michigan State? No.
Trevon doesn't fit with Duke either, but Ky was like that too, and he was nasty enough to where no system could trap him. Trevon is one of the best passers in his class, and his handles is deadly. You line him up with an elite SG Trent, shooter Tucker, Senior Allen, and the rest and he's straight. His decision making will be an issue but he's going to play for one of the greatest coaches so it'll improve.
Off topic: Tre Jones, Tyus kid brother, now that kid was made for Duke. He might be my number 1 PG in this class.
