Let's assume this

The Kings and Pistons agree on $44M AAV for Duren, so that means Detroit is only giving up Duren while the Kings are only giving up Sabonis.

Here's where the problem comes in, and it's the Base Year Compensation (BYC)

Because Duren's new salary will be more than 2x his old salary and it's a sign-and-trade, the BYC kicks in:
On Detroit's side, Duren only counts as 50% of his new salary = $22M outgoing
On Sacramento's side, he counts at the full $44M incoming

Why a 2 teamer is just mathematically impossible
Kings are taking in $44M, so they must send out at least $35.2M, which works because Sabonis's contract for this season is $45.5M
But Detroit sending out $22M with the BYC can only take back $31.1M max
Sabonis is $45.5M, which makes it $14M over Detroit's legal limit

The only way to attempt is a three teamer where
Team C needs to be an under the cap team where room + outgoing salary >= $45.5M, and whatever player they send Detroit must fit under Detroit's $31.1M BYC limit. So something like $20M in space + a $25M player works perfectly. (Doesn't have to be exactly that either; any version works as long as the player fits under Detroit's $31.1M BYC limit and the third team's space + outgoing salary adds up to $45.5M+)

So the main issue is finding a team that can willingly take Sabonis. Which is why I really doubt this would even happen now, looking more into the contracts.

But there is also this: Detroit taking the $25M player back does eat most of their $14M of cap room and pushes them over the cap, so it only works if Detroit actually wants that player.

Please correct me if I am wrong, but I did this based on Keith Smith's post about how an S&T works under the new CBA a week ago.

Let Scott and BJ Armstrong do what they can tonight with Duren to convince him to put even more pressure on the Pistons. Even tho pistons have all the leverage, there can be workarounds.

Duren and Sabonis's agents both work for the same agency, so I wouldn't be surprised if both their agents put pressure on the FO to figure this out.

Reminder this is what was said yesterday from Marc's article
"Most notably an anticipated sign-and-trade run at Detroit's Duren potentially involving former All-Star big man Domantas Sabonis that will begin with a face-to-face meeting with the Pistons' restricted free agent on Tuesday night."
