Let's reason this one out.
The Maloofs were pretty clearly the hirers of Musselman.
I think most people think they were instrumental in hiring Theus.
Natt was a complete void, directly caused because the ORGANIZATION (primarily Petrie) didn't have a capable assistant ready to take the reins in case things blew up (which they of course did).
Enter Westphal.
I really, really, REALLY doubt that the Maloofs picked Westphal.
He has Petrie's fingerprints ALL over him.
Older guy, "seasoned", player's coach, easygoing, passive, etc.
IIRC, Petrie went out of his way to make it clear that Westphal was his man especially around the time the Kings picked up Westphal's contract option.
Here's an article littered with how close Petrie and Westphal were, and how the team was all their picks:

Cisco is the ONLY King remaining that pre-dates Petrie and Westphal's direct decisions.
This current roster debacle cannot reasonably be placed at the feet of the Maloofs.
If we are concluding that the last 2 years was an utter waste of learning time that hasn't coalesced into a competitive team, than Petrie and the FO,
as well as the current assistant coaches and trainer(s) on the team, are to blame MUCH more than the Maloofs, who
do not make the day-to-day decisions for the team.
