The Bucks have considered moving on from Portis and I wouldn't be surprised if he is tired of coming off the bench. This would be a solid trade package for him as they get two bench players that can defend and shoot in return, along with draft compensation.
The Pels need to move away from Ingram. This deal lands them Huerter and Barnes, who will contribute significant minutes off the bench, along with draft compensation. I could see the Pels taking a different deal for a center, but this is a solid option. They could even use some of these pieces along with Hawkins and picks to grab a solid center. I think the rotation would look like:
DJ-Herb-Murphy-Zion-C (maybe WCJ?) with Alvarado-GTJ-Huerter-Barnes-Missi off the bench
The Raptors are kind of in rebuild mode but getting a veteran like CJ could help their young studs a lot. GTJ is likely to sign elsewhere, so why not get something for him?
The Nets are in a weird spot where they have contention level pieces but not the stars around them. They start their rebuild with a big boost from Sabonis. I know this is very unlikely but getting a former All Star for Cam, Claxton, and 3 FRPs is a solid deal. I was also just looking for a team with the assets to get Sabonis that would make sense for the Kings.
I don't think that Sabonis will be a championship piece for the Kings, so they decide to move on and upgrade their depth while they are at it. This would make them a dark horse contender in the West with a rotation of:
Fox-Ingram-Murray-Portis-Claxton with Carter-Monk-Ellis-Cam-Achiuwa off the bench
