Cavs would be stupid to move Nance so truthfully no. Marvin Bagley... that's a good target.
Anyway, if I was JZ I would do a sign and trade for Lauri and give up JC. Then I would look to see what is out there for a six man.
Jazz feel like they've caught lightning in a bottle with Clarkson. I don't see them moving him.
One thing the Jazz could do is bring in a big athletic wing to play the 3 and treat Bogdanovic as a 4. It may just be semantics, but it's possible Bogey can guard 4s better than 3s. So Bogey becomes this Danilo Gallinari-like stretch-4 that you don't expect too much out of defensively, and the Jazz instead bring in a more perimeter-oriented wing defender to guard the Paul Georges and Jamal Murrays. So now you're looking for someone more like Lu Dort or Mathisse Thybulle instead of Christian Wood.
I'm guessing the Jazz were trying to move up in the draft to get Chris Duarte or Trey Murphy for this reason. It doesn't look like Miye Oni is going to cut it.
