Well... I think there could be a framework for us to get in that trade, but we'd have to send out quite a few players...
Something like:
SA: In: Westbrook, picks - Out: McDermott, Poeltl, Richardson, KBD
LA - In: Irving, McDermott - Out: Westbrook, picks
BKN: - In: Poeltl, Richardson, KDB, picks - Out: Irving
Now before you say Brooklyn doesn't need Poeltl, I'm simply laying a general framework where we could be involved... Probably it'd require some team that could use Poeltl giving something up that the Nets need (Chicago? Toronto? Utah?). But the overall salary structure works.
I don't think the Nets would require all that much in terms of picks compensation for 1 year worth of Kyrie, he's a distraction and his market is reduced to one team. So probably one unprotected from LA plus something else.. maybe an unprotected 1st from LA plus whatever a 4th team that wants Poeltl can give them.
Basically for us, we take on about 10M worth of salary (which leaves plenty of room to facilitate other trades) and we get out of McDermott's remaining contract. Richardson is unlikely to command a 1st in return so he's the price for moving McDermott (maybe a couple second rounders on top) and trading Poeltl embraces the rebuild. As compensation we get maybe Philly's 2023 1st (owned by Brooklyn) and an unprotected pic from LA, plus ridding ourselves of McDermott now.
Now I'm not saying this is an easy or likely scenario, but it's a working scenario that, give or take a few picks could be a reasonable middle ground for all parties.
