I mean, Keyonte could develop into a PG. When he started at the position for the first stint he was putting an emphasis on classic game manager style. Hardy raves about his pattern recall and how much film he watches.Utah doesn't really have a point guard. We have shooting guards that play that position out of necessity (like George, Sexton, Clarkson). Dunn might be the exception, but honestly he is a solid backup and not really a starting PG on a good team. Castle would probably be starting here by the end of his first season barring trades. I think it is obvious that Clarkson or Sexton will be gone by the trade deadline anyway, preferably JC.
I dont think if we drafted Castle he would be the clear starting PG if he and Keyonte started. It would be like we have two starting guards and let it play out.
