High D1 players usually are "the guy" in high school and have to learn in college to defer and complement. It's not a bad thing to have a pass-first PG who has to learn how to assert himself offensively, because in some ways that's easier to learn than the distribution skills. Of course some guys just have a meek personality and never develop that aggressive mentality on the court. JC was good at instilling a disciplined aggressiveness. Mike Miller, now assistant coach at Memphis, stood out to me as a high school player for making things happen by sheer aggressiveness. Aggression and tempo go a long way on the offensive side.
