I guess if you
So, do the Kings roll the dice? This would be, pretty much, the one and only way to get a second top 20 player in SAC without another draft miracle (see: Demarcus Cousins).
Look at it this way. Would you rather have option A or option B?
Option A
Draft a top 10 player in the 2017 draft (which is supposed to be the strongest in the past decade) in hopes that you can move that player in a trade for a 2nd star on a longer term deal or that he becomes the 2nd star next to Cousins. Also, you'd be able to keep other assets like Richardson, Bogdanovic, Labissiere, Cauley-Stein, & Papagiannis who might just end up developing into stars, and if not, potentially good starters/rotational players.
Option B
Get Millsap as our 2nd star and run the risk of him leaving in the offseason, or if we do resign him, run the risk that his age catches up with him (32 next season) and he's not able to help carry this team to the 2nd round/WCF. In the meantime, you lose a top 10 2017 pick and some other assets such as Richardson, Bogdanovic, Labissiere, Cauley-Stein, & Papagiannis.
Personally, I'm taking Option A. I think it would be a very bad move to lose our pick this year. I know everyone wants to win this year (me included - check the game threads), but in the long run, it sets us up for the brightest future. With the new CBA, I'm very confident we keep Cousins so let's start gathering young talent right now to develop around him. Trade Gay for Payne. Trade Casspi for Delon Wright. Trade Collison for Dekker/McDaniels. That way we secure our 1st this year and get some young assets for our expirings.
Payne / Wright
Temple / Bogdanovic / Richardson
Dekker / Barnes
Labissiere / Cauley-Stein
Cousins / Koufos / Papagiannis
***2017 1st***
That's a good amount of youth and potential to develop around Cousins.
