The Cavs get LeBron back to Cleveland to help them more successfully contend in the East next season.
The Timberwolves finally get the true Star point guard that they have been looking for and maximize their offense for next season while also retaining cap flexibility the following offseason (given Harden is on an expiring deal) to potentially sign a younger Point Guard on the open market for no additional assets.
The Pistons risk losing Jalen Duren for nothing if they are unwilling to match a large deal, so they move to complete a S&T and as a result they get a very good center just entering his prime in Naz Reid at a much more reasonable salary (compared to Duren's next deal in this scenario) that gives them more room to add even more depth. This is exactly what they need to retool and contend in the East next season.
The Wizards trade their own 2026 and 2027 Second Round Picks for DiVincenzo, who the Timberwolves would need to trade to match the incoming salary of James Harden.
The Lakers pay a high premium for a Sign and Trade, and finally secure their long-term young center that they have been searching for ever since Magic Johnson traded Zubac for nothing.
