I was thinking of something very similar. Salmons doesn't need to be amnestied though, only $1 million of his contract next year is guaranteed so he's essentially an expiring contract now with a $1 million buyout tax. That's a drop in the bucket for just about any NBA ownership group. The trade also works with either Landry or JT, whichever one New York wants more. We'd be sacrificing a little bit of salary cap flexibility this season to get another 4 year contract of the books and add a valuable role-player. The long-term implications for us would be that we enter the new arena year with only 4-5 sizable contracts on the books (Cousins, Landry, McLemore, 2014 first round pick, 2015 first round pick). That leaves something like $25-30 million in cap space to work with that year. Enough to be the high bidder on whichever free agent fits best with our lineup at the time.
I can see New York wanting to get out of the Amare deal and adding in Thornton and Thompson/Landry at least gives them some guys they can work in to the rotation right now. They have no draft pick this year, so there's some level of urgency to start winning games. Actually, that probably rules out Landry. The sticking point here is that we're obligated to do something with Amare. At his current level of "production" he's worse than any of our current PFs (pretty hard to believe, but it's true). You don't want to overshoot this though and end up playing yourself out of a good draft pick. I would also think about packaging IT in the deal. Why? Because he makes the offer more enticing in a "win-now" context for New York, and he's probably not going to be re-signing with us anyway.
So... Amare and Shumpert for IT, Thompson, Thornton, Salmons?
Eh, that sounds like an overpay to me. Thomas and Thompson are really only assets to certain teams though. Thomas would be worth a lot more if he weren't expiring and Thompson represents a 4 year commitment. I'd be reluctant to part with both of them in one deal, but the goal here is to consolidate some future salary cap flexibilty and swap some of our current mismatched parts for another young player who should fill a need for us (wing defender, backup SG). Shumpert might be the better long-term asset here, either as part of our rotation or as another young and talented trade chip. I'm not sure I pull the trigger on that deal yet, but I'd think about it. We probably get worse in the short-term and better in the long-term, depending on how highly you value Shumpert, which is what we want right now.
That's a lot of moving parts but essentially it boils down to a swap of backups (IT for Shumpert) and combining 3 sizable contracts (1yr, 2yr, and 4yr) into one big 2 yr contract which becomes a big expiring contract in approximately 5 months.
Awful. Your insistence on getting rid of either Landry or Thompson at all costs is getting ridiculous.
