You're trying way too hard to negative here:
We had a deal lined up for Bogi that got blown up by another team violating NBA tampering rules. Let's blame that on Monte. Then the Hawks played hardball in RFA. They tried to S&T junk to us, and we passed, and when they put up the offer sheet, it was too big, so we declined. That's the way the cookie crumbles.
Not an excuse to not walk out with at least a trade exception.
You mean that "asset" who has been waived by two teams in the 8 months since we waived him and is no longer in the NBA?
There was nobody named Richardson (and from the Kings side there was nobody else at all) involved in either Delon Wright deal. Thompson at the very least is a playable backup big and would appear to be a good locker room presence. Wright was also playable, but was stuck in a guard glut.
Davis is under contract for two years, and has already played more minutes for us than any of our second round picks since Frank Mason. Second round picks rarely turn into anything, if you turn them into a player like Davis you should be happy.
Bjelica was benched and miserable and expiring. At least Harkless plays and seems happy to be here and has also been signed two years at a pretty bargain price.
This hasn't even HAPPENED.
Notably, you failed to mention that Monte has drafted Haliburton and Mitchell, who are clearly rotation players at worst.
I mean, I'm 100% on the fence about Monte, he's got a lot left to prove, but let's not get silly.
