I think I'm half-way persuaded by HH -- not a down payment, but more just a "don't forget about us as you're negotiating your next deal -- we might just have what you want there as well." The kind of thing that makes it just a bit harder for the trade partner to ignore your next offer.
I'm also reasonably sold that the Jazz were happy to do the deal on its own. It's been no secret (for a long time) that the Jazz had liked THT from the draft process.
I think I'd put the Pacers trade with the Lakers at 60%. Bigger names, younger players who have been long term starters.
But HH is right that if the Lakers prioritize clean books next year, we can make a very competitive offer: Bogey, Beasley, (likely Reddish), and (if needed) Vanderbilt. I think that's the kind of offer that would at least cause the Lakers to think twice.
