I'm not saying he's a bust, but did you see the video of the practice? The problems with his shot aside (and they looked significant), he looked lost, totally without confidence. Not a good look. This is something I've never seen before, so I'm not sure exactly what to expect going forward.
Why don't we let it play out a little bit before we throw in the towel on the #1 overall pick. We saw him in summer league and he, and his shot, looked pretty terrific. Go watch the youtube videos.
