Right on. There's a template for this player already and not to get too ahead of ourselves, but Castle is bigger than Holiday and had more success in his college season and is more of a playmaker than Butler. Whatever the results are, these are the players to tab.
Castle's route to NBA success doesn't really depend on his jumper. His steps to success are already present, only relying on improvement and adapting. Too many of us are obsessed with shooting and the short term, as if getting a single-skill shooter in will fix everything next year. It won't.
Castle's success, if he hits, will be lasting and long-term, and that's independent of how well he shoots. He already gets huge amounts of space in basic pick-and-rolls. Even if he just develops a midrange - which I think is highly likely, as it looks very good - then he's a lot of trouble. Playing next to Wembanyama, who is also a developing long range threat, it's a lot for a defense to handle.
Castle is going to find the floor, a lot, simply with the package he already has. If he becomes any level of threat to be accounted for from deep, there's a major threat. There continues to be a misperception of him as a wing, when he's going to be part of the top of the key playmaking process.
