I like the idea of getting Detroit in the mix to facilitate a three-team trade. This presupposes that (1) Sacramento, with a new owner, is looking to make a big splash and (2) Stan Van Gundy wants a fresh slate, including Josh Smith out of town.
Something like (need to mess with the salary filler and/or trade exceptions):
Boston outgoing: Rondo, salary filler and/or trade exceptions
Boston incoming: Monroe (s/t at ~14 million per year), Stauskus, I. Thomas (s/t at $6-8 million per year)
Detroit outgoing: Josh Smith, Greg Monroe (s/t)
Detroit Incoming: McLemore and SAC and/or BOS salary filler
Sacramento outgoing: Stauskus, McLemore, I. Thomas (s/t), salary filler
Sacramento incoming: Rondo, J. Smith
I don't love Monroe as a defender or rim protector. And I don't love the pairing with Sullinger and Olynyk. But I am intrigued by him in Stevens' motion offense. Smart players who can shoot and pass (e.g., Monroe, Olynyk, Sullinger, Stauskus, Young) could really fit that system. If they could find a way to dump Green in favor of a SF like Heyward or Parsons that team would have the potential to be dynamic offensively and fun to watch (if not ready for prime time).
