DAL OFFSEASON: Trade & FA | Mavs "mostly done...but you never know."

[Mapka]

Possible trade with the above outline:

Chi out
LaVine/Sato

Chi in
JB/JJ/Green/Kuzma/18/31/2025 first/as many Dal seconds as they want

LAL out
Green/Kuzma

LAL in
Kleber/Curry/DFS/Dal future second

Dal out
JB/JJ/Kleber/Curry/DFS/18/31/2025 first/the amount of future seconds it takes to make the deal work

Dal in
LaVine/Sato

I'm pretty sure, there is no team in the NBA that would see Kuzma/Green having more value than Kleber/Curry/DFS on their current contracts. 
So why is LAL involved to grab the value and an additional second? 

I won't speculate what Lavine would cost, but this just doesn't make sense at all. 
And the MBT would look elsewhere, if this is the price.
