This is another weird one and a variation of the 3 team trade I posted a bit ago. I tried to take into account each team's current roster situations and future aspirations so check out the team by team breakdown below. I'll also just add that I really don't want to see Obi go. However, it's clear that as long as Randle and Thibs are here (and honestly Randle has earned his place this season), then Obi just will not get any playing time. He has shown more and deserves more so this trade gets him to a team that is all about developing young players right now.
Knicks: The Knicks are in a weird and a tough situation right now. Since Mitch has been out it's been clear that despite not having him available, Thibs is just not open to changing his game plan on either end of the floor. They bring in a capable center in Mo Bamba (who also is a Harlem native, always nice to see players come home to NYC) who can provide some rim protection, score some and as a bonus can stretch the floor a bit (although Thibs will probably never build that into the offense). They also add a couple of wings in Bey and Hart who I think will fit in really well. Hart is part of the Villanova group along with Brunson and Arcidiacono so I think he'd fit right in and hopefully remember that he can take more 3 point shots! Still, despite his struggles this year, he has shown the ability in the past to add on offense and is a solid defender. Bey is still a work in progress but has played better this year and again can defend so he'll appeal to Thibs. All 3 players could go into the rotation and could hopefully lift a struggling bench that needs some firepower. They also swap FRPs with the Magic and get a better one in return because Obi is the player with the higher ceiling (more on that in the Magic breakdown below).
Pistons: The Pistons mainly do this for the draft picks, which while they are all second rounders, they still get 4 of them and a player in Reddish who they'll hope they can be the team who finally unlocks his potential. But Diallo and Bey have reportedly been put on the market so they're open to moving them. This Pistons team is definitely in asset collection mode after Cunningham's injury so this gives them a bit more in that department (and if they want some FRPs they can always trade Bogdanovic).
Blazers: The Blazers aren't getting enough from Hart this year and likely can't afford to keep him anyways next season. They add an interesting center in Hartenstein who has been misused on this Knicks roster but would fit in a lot better under Billups who is more flexible than Thibs. He's also young and on a team friendly contract. The Blazers have needed a different look at center (Nurkic has been solid but it's definitely an area they can improve) and hopefully Hartenstein is it. They also get Diallo from the Pistons to add some youth and another weapon off the bench.
Magic: This is probably the weirdest part of the trade. The Magic get Obi, who again has been underused by Thibs but has shown why he was a lottery pick when he actually gets the chance. They still have too many bigs but they clear some room by moving Mo Bamba and I could see them moving a player like Isaac if he shows some consistent play this season. The controversial part of this will likely be the pick swap that sees the Knicks send their protected FRP from Washington for the Magic's pick from the Bulls. That pick is likely to be around the 10 spot so I can see why it may seem like the Magic are getting screwed. However, Obi is a former lottery pick and has a much higher ceiling than Mo Bamba. They also just have sooo many young players on their roster now and if they added two more top 10(ish) picks in the 2023 draft, it's hard to see them having any time to develop (especially since Isaac has now come back). It's possible the Knicks would have to give either their own pick or the Dallas pick instead of the Washington one but since this one is unlikely to convey this season, that works to their advantage in giving playing time next season.
Anyways, definitely another weird one and appreciate any feedback in the comments!
