Here's my ranking. I'll leave out Cooper and Harper since they're not worth thinking about.
1. Ace Bailey
Of course, he could be a bust. But he's the player Utah wants to be the 'ace'.
2. VJ Edgecomb
Utah doesn't have an ace stopper anyway. VJ can fill that role, and he can be the vanguard of a counterattack and a fast break.
3. Tre Johnson
If options 1 and 2 fail, Utah will eventually have to solve the problem of 'no first option', and Tre has a high probability of doing this.
4. Kasparas Jakučionis
A handler capable of 3-points... Assuming other handler prospects can't fix their weaknesses, this guy is a decent insurance.
5. I don't think there is anything else. We already have Kessler and Filipowski, don't tell us to add another big man.
