I don't think Douby was a bad pick at all. Can't complain about big men, since outside of Josh Boone (who had questions about his passion and consistency), there weren't really any available to pick from other than one-two year project, Joel Freeland. And Josh Boone ended up getting shoulder surgery and is out for awhile. Besides, were getting at least one of Amundson/Williams, who were both considered R2 picks, but the explosion of Int'l players changed that and put many solid prospects out of the draft.
