I'd like to cross off post players from our 'potential target list' based on the fact that the Jazz were unwilling to trade Millsap, if what PKM said is true. My thought process is that if we were so high on a post player, why wouldn't we be willing to trade Millsap to acquire him since Favors and Kanter are clearly our future? Just a thought.
This most likely leaves us with:
Austin Rivers (though, PKM said he heard it's not a SG)
Quincy Miller
Terrence Jones
Terrence Ross
Jeff Taylor
Tony Wroten
Royce White
The second piece of information that we have is that we're going for a pick around #15, meaning the Jazz believe their guy will be available after the lottery. In other words, if we were in love with a prospect and were willing to trade for a pick, why would we trade for a pick that is below where that player is expected to be available? We seem very confident that this prospect will fall to 15, which makes me believe it's not Terrence Jones. At least, he seems like the least likely to fall that low of the players I listed, so lets cross him off the list.
And I suppose we can cross Rivers off the list, assuming the Jazz view him as a SG more than a PG.
Next, if I really had to guess, I'd cross Ross and Wroten off the list. They both seem to have low BBIQ's--something I believe KOC values more than most.
This leaves us with:
Quincy Miller
Royce White
Jeff Taylor
Again, we have to keep in mind that we're aiming for a 15ish pick, meaning not only do we expect this player to fall outside of the lottery, but we probably don't think he'll be available much later than that. To me, that suggests Quincy Miller. I'm not sure many mocks have White or Taylor going ahead of Miller; it seems like they could easily fall to 20, IMO, but I have a harder time seeing Miller fall that far. So why would we be trying so hard to get a pick at 15, if the player could be had a little lower than that?
Although, Miller kinda seems like the least "Jazz like player" to me of those three, so who knows. This is all just major speculation by me, but I'd probably put those three at the top of my list of guesses, based on the rumors we are hearing from PKM.
Edit: PKM also believes it's a SF, and all three of those players (Miller, White, Taylor) could be said to be SF's. These are definitely my guesses.
