I don't think Burke is part of the plan, but Dotson I kinda like. I'd sacrifice him to move either Courtly or Timmy, because the former isn't useful for us and the pain of the latter's contract outweighs his utility. But I'm not optimistic.
Let's play "Who says no?":
Memphis or Toronto?
Marc Gasol & Ivan Rabb for Jonas Valunciunas, CJ Miles, and two second round picks (Grizz can't take back any more money without ending up in the luxury tax, although they could use Delon Wright. This would be Memphis admitting Gasol has low trade value. Raps would have to convince one of Gasol or Ibaka to come off the bench)
Sacramento or Washington?
Zach Randolph, Iman Shumpert, Kosta Koufos (all expiring) for Otto Porter, Ian Mahinmi and a second round pick (clears >$42 million in cap space for Washington next year, when Wall's contract spikes, and takes them out of the luxury tax this year. Sacto upgrades Shumpert in time for a playoff run, but at a heavy financial price)
San Antonio or Memphis?
Patty Mills, Pau Gasol and Derrick White for Mike Conley and Ivan Rabb (San An rarely makes in-season deals, but Conley-Derozan-Aldridge are all on the same timeline, and Conley just feels like a Pop type player. White is the draw for Memphis, who only have their pick protected top-8 this year and top-6 next year)
Boston or Orlando?
Gordon Hayward and Terry Rozier for Aaron Gordon and DJ Augustin (Boston gets out of the tax and more importantly clarifies the roles going forward for Jaylen Brown and Jayson Tatum. Marcus Morris gets squeezed, despite an excellent year, but he's a UFA this year. This presumes Boston doesn't want to pay Rozier. Augustin would be an offensive upgrade, and Gordon would be useful as a scorer who didn't need plays run for him. As for Orlando, they'd have to love Rozier as ready to become a Patrick Beverley type starter, but they could think playoffs next year if Hayward improves even slightly)
Philadelphia or New Orleans?
Markelle Fultz, Wilson Chandler and the Miami Heat 2021 unprotected #1 for Nikola Mirotic, Etwaun Moore and a second round pick (NOLA gives up this year, since everyone else knows they aren't making the playoffs, but gives them a roll of the dice for next year in Fultz, either with Davis or as part of post-Davis core with Jrue and Randle or whatever treasure they secure for Davis. The Miami pick is a major trade asset. Philly gets much needed shooting, and perhaps makes themselves the team to beat in the East)
