I don't think the Cavaliers have given up on last year's #1 pick, Anthony Bennett, just yet. Aside from Carter-Williams and Olapido, no one from that draft class has really made a dent in the league. Bennett just has to get himself into shape and he could be a Draymond Green type player.
The Cavs should shop the #1 pick to the Sixers, who are looking to move into that #1 spot. The trade would be the 1st and 33rd picks for the Sixers 3rd and 10th picks. They'd still end up with either Wiggins, Parker or Embiid at #3. But lets say the Sixers move up to get Parker. Milwaukee would take Embiid to replace a troubled Sanders. That would leave Wiggins for the Cavs. At #10, I really like Nik Stauskas. He reminds me a lot of Klay Thompson with his ability to shoot the ball. I'm not a big fan of Waiters and sees him as a guy that should come off the bench like a Jamal Crawford, which is just as important of a role as being a starter.
