Good points (and point taken on your "on a given day") - I disagree on TO's as PG/SG/CG, looking at what I've seen of both of them, neither's turnovers are primarily PG/running the offense turnovers.
I hope Simpson improves to ~30% from 3, I hope his shot selection gets better, I hope he realizes contested pull up 2's are not good shots, I hope he drives and kicks and throws lobs.
Consistent playing time and shots vs what he got last year, better shooters to kick to, a year of experience, Pike's optimism towards him - all good signs. I also see a kid who is a great story, fantastically mature, confident and well-spoken and can see why it's easy to be overly optimistic about him.
