The most frequent things I have heard from the Bucks are these:
1. They would pick Parker over Wiggins. More b/c new ownership needs to hit on a solid player who can help right away than that they think he will be better over his career than Wiggins. Wiggins is also a little more redundant with The Greek Freak than Parker, who can play PF, would be.
2. Embiid scares them even if the back is fine. They have 44 million locked up in a defensive PF-C in Sanders and through his agent Embiid has let it be known he doesn't desire to play in Milwaukee.
3. They would entertain taking Exum b/c with his size (6'6" apparently) they can play him alongside Mayo and Brandon Knight in a great 3 guard rotation.
If they took Parker or Embiid and Exum fell to us do you think they would consider trading one of those two guys here for pick 6 (Exum) and trading Jeff Green and Faverani for Sanders? That saves them 33 million, gets them a solid backup center for ZaZa as they tank again and hope to land a lotto center next year, Green is the instant sure thing at SF who gives them 17-19ppg.
