Jazz would have a 20% - 30% chance of moving up into the top 4. Looks like those are the best odds the Jazz are going to get. I like Black for the Jazz, especially if they're going to use multiple creators, like they have been this season.
Gradey Dick is the most Kyle Korver-like pure shooter, but I worry that this archetype might not be as valuable in today's NBA where teams are loading up with wings and switching defensively. A player like Jett Howard, who has more self-creation and shoot-off-movement potential might be better. Offensively, Howard might be the most comparable to a Klay Thompson in this draft.
One guy I'd look at in the late 20s would be Jordan Walsh. He's a relentless defender, and he has more ability to facilitate on-ball than he's shown at Arkansas. He should also be able to knock down shots. He's kind of a Swiss-army knife at 6'7" with close to a 7-ft wingspan.
