It is fair to hope he improves.
He plays with intelligence. If you asked me what I hoped for from him this year, I would have said he could work on his body, lose 10+ lbs and become just a bit quicker as a result, and become a more consistent shooter and finisher, which is necessary for any young player.
So far, he instead looks just a bit heavier than last year, not more fit, and he isn't showing any improvement as a shooter and scorer yet. So, yeah, I'm disappointed.
