I think Hammond has a bit of an inclination to "get cute."
Given that and what you wrote Tschmack, I am not in favor of trading down for the #4. I want Parker or Wiggins. Talent along with more of a sure thing.
On another matter, last night I recalled the discussion around who the Bucks should draft #1 when they took Bogut. Quite a few preferred Marvin Williams. He hasn't done a whole lot, has he?
