I agree with this take 100%. Would hope the sixers pick would be 3 or 4 though. Doubt Russle or Mudiay make it past there. Although Winslow/Hezonja (less so) would make me happy at #5 too, if the afore mentioned guards are gone.
Here are the odds for where the Kings could draft
#1 6.3%
#2 7.1%
#3 8.1%
#4 0.0%
#5 0.0 %
#6 43.9%
#7 30.5%
#8 4.0%
#9 0.1%
So there's actually better odds that the Kings pick 7th than in the top 3. And there's also a miniscule (but non-zero) chance that they pick 9th.
To me I see things this way:
If the Kings get the #1 pick you either take Towns are exact a ransom for the pick (say #3 or #4 from Philly plus Noel)
If the Kings get #2 or #3 and Okafor goes first you take Towns or trade the pick. If Towns is gone I think you trade the pick
At 6, 7 or 8 my first choice would be Cauley-Stein. If he's off the board then I'm not sure where you go. I think one of Mudiay or Russell may slip, probably Mudiay. He's not a great fit, but might be worth the gamble. Porzingis is a boom or bust, high risk/high reward pick. Hezonia is a smooth scorer but that's three straight SG picks. I think Winslow is gone by #5 so I think after WCS and Mudiay (if he slips) Stanley Johnson would be my pick unless there's a trade out there that makes a lot of sense.
Rarely do you get value for the pick in trade if it's not top 3, historically speaking.
