Staying at 9 our worst case scenario is starting to look like maybe Walker.
I would take Hendricks and Black over him comfortably.
I think the Jazz are going to seriously consider trading up to #6 in order to draft one of Whitmore or Walker, as neither one is expected to make it to 9. Personally, I would be happy with Walker at 9, I would be lukewarm at best with Hendricks, and I would be disappointed with Black.
