I'll lead with the trade itself. I've made two variants of it.
Firstly:
https://tradenba.com/trades/suaiIn0a-Boston trades: Enes Kanter, Robert Williams, Romeo Langford, #14, #26, #30
Boston receives: Jakob Poeltl, #5, #41
Cleveland trades: Dante Exum, Cedi Osman, #5
Cleveland receives: DeMar DeRozan, #11, #26
San Antonio trades: DeMar DeRozan, Jakob Poeltl, #11, #41
San Antonio receives: Enes Kanter, Dante Exum, Cedi Osman, Robert Williams, Romeo Langford, #14, #30
Why for Boston: First and foremost we get to move up in the draft. This gives us a shot at Hayes, Avdija, Okongwu, Wiseman, whoever we want! We get a strong defensive-minded bench big in Poeltl who can pass and is super efficient, and we get an extra second rounder in a role-player deep draft. I think given our potential roster crunch such a move could be appealing.
Why for Cleveland: They suddenly get an All-Star level wing in DeRozan who could propel them into playoff contention if Love stays healthy. DeRozan would be a great mentor for Kevin Porter Jr. If it doesn't pan out, they still get decent draft compensation to build around Sexton and get a huge expiring.
Why for San Antonio: I expect them to fully embrace the rebuild soon and say bye to Coach Pop. This kickstarts that for them. Moving down 3 spots from 11 to 14 but turning their 2nd into a late 1st is a win in this kind of draft. They also load up on expiring role players (Kanter and Exum) and cost-controlled prospects (Langford, Osman, Williams). Moving Aldridge as well could make this offseason massive for them.
The second variant is basically the same, except we don't acquire Poeltl and don't give up Timelord:
https://tradenba.com/trades/zj0_IEJUaI am a big fan of Poeltl, so I would like to nab him. He reminds me a lot of Baynes. Statistically they're very very similar:
https://stathead.com/tiny/z4ZRnPoeltl is a better passer, offensive rebounder and is much more efficient, but Baynes is stronger, better at defensive rebounding and a much better shooter. Poeltl is a really good defender.
I'd love to see us walk out with a draft of Hayes at 5, Paul Reed at 41 and Sam Merrill at 47. Sign a guy like Alec Burks / Furkan Korkmaz / GRIII with our MLE and take a flyer on Boogie Cousins and we have a legit shot at raising #18.
We'd have a rotation of:
Kemba Walker / Killian Hayes / Carsen Edwards
Jaylen Brown / Marcus Smart / Sam Merrill
Gordon Hayward / Alec Burks / Semi Ojeleye
Jayson Tatum / Grant Williams / Paul Reed
Daniel Theis / Jakob Poeltl / DeMarcus Cousins
Guys like Smart and Poeltl could start when necessary, but I'd be just as happy to keep developing Timelord.
