Several Utah Jazz players, including Lauri Markkanen, could be on a new team next season. However, all indications are that the Jazz will keep Markkanen 10 times out of 10 over giving him up for 25 cents on the dollar. This trade pitch below would fit the latter scenario, which is why Utah would never do it.
Bright Side of the Sun's Jon Voita proposed a trade between the Jazz, Phoenix Suns, and Los Angeles Clippers in which the following would occur.
Suns receive: Markkanen, Ivica Zubac
Jazz receive: Norman Powell, Grayson Allen, Derrick Jones, Jr., 2029 First Round Pick (the conditional one the Jazz traded to the Suns at the deadline), 2030 First Round Pick (via LAC)
Clippers Receive: Kevin Durant
The explanation for why the Jazz would do it would be to bail out of Markkanen's deal. Utah could hoard more picks in the process, and it helps with their short-term competitiveness and cap flexibility. If that's what the Jazz were looking for, then maybe they'd look into something like this, but it's been pretty clear that this is not the kind of deal they would take.
Even though Markkanen has come up in trade rumors, every indication is that while he could be available, the Jazz will only trade him if a trade partner pays a hefty price to get him. That means said trade partner wouldn't just give up draft assets, but young, promising players attached with quality draft assets.
Markkanen's deal may be expensive, but Utah has the leverage of having him on their payroll for the next four years until someone meets their demands. This deal wouldn't come close to that, and adding a solid batch of players who wouldn't be long for Utah also wouldn't make it any more appealing for the Jazz to accept.
For all we know, Utah may be a little too optimistic to believe a team will give up the farm for Markkanen, but a deal like this says they had no problem selling low on him and did so when they had the chance. Unless anything changes, the Jazz are not operating like that.
The Jazz want quality picks, not quantity
The main reason why the Jazz made that deal with the Suns back in February was to consolidate their picks for a better one. In other words, Utah signaled their awareness that they have too many draft assets and are now on the prowl to upgrade them or add better ones. In other words, they are done hoarding picks for the sake of doing so.
Getting that pick back goes against that philosophy. While that Clippers pick could be valuable in five years (depending on the protections), the Jazz would basically trade Markkanen for one pick. That's the same value they got for Mike Conley. As impressive as Conley was then and still is, Markkanen should fetch more.
So the Jazz don't get equal value player-wise (their present), and likely wouldn't get valuable assets (their future) back for Markkanen. That fits the criteria of no steps forward and two steps back for them. When deals like this are presented to them, they'll immediately think they're better off keeping him around.
