I'm mildly concerned because of the poor final year in college, combined with what we've seen so far, but I'm chalking most of it up to figuring things out in his first year in the league.
I am anticipating that his catch and shoot game will be the focus of his summer and will be much better next season. This is admittedly based on the fact that he was a good 3 point shooter for his first 2 years in college, and also that he "looks the part" even though the results aren't there yet.
