Pretty lengthy but a damn good read

DeMar DeRozan: Here's the likeliest big-name 2021 addition. San Antonio could certainly afford to re-sign DeRozan, but they have so many young guards that it would make little sense to do so. Even if it did, reports have suggested that DeRozan has been interested in a change of scenery for years. Other teams would be scared off by DeRozan's limitations as a 3-point shooter, but Dallas, with Porzingis and a plethora of other shooters, can afford to devote big money to a mid-range gunner. He wouldn't help their defense, but adding him to the Dallas offense would help so much that, for the time being, that might not matter to the Mavericks.
For example: say Dallas carves out enough space to sign DeRozan without losing Hardaway. They could sign both to three-year pacts. DeRozan, who turns 32 this offseason, won't get a longer offer. The other older guards available in 2021 are in the same position. From there, they'd assume that Doncic, Porzingis, Hardaway and DeRozan would be their core for the next three seasons, and would simply rely on short-term deals to support them with defenders. And then, after three years, they'd let everyone but Doncic walk and completely reshape the team in free agency.
Porzingis for Kemba Walker. Dallas was reportedly interested in Walker as a 2019 free agent. He chose Boston. Now he's starting to decline before their very eyes, and with Jaylen Brown and Jayson Tatum now on market-value contracts, they won't have the cap space to sign a replacement. Porzingis is significantly younger and fits their timeline, but his contract lasts a year longer than Walker's. That would essentially be the premise of the swap. Dallas gets max cap space a year early. Boston turns an injury-plagued 31-year-old into an injury-plagued 25-year-old.
Porzingis for Andrew Wiggins. If any power forward could protect Porzingis defensively, it would be Draymond Green. Think of the spacing in lineups featuring Porzingis, Stephen Curry and Klay Thompson. Most importantly, it's a chance for Golden State to take an upside swing without sacrificing its most valuable assets. They could keep James Wiseman and their picks while potentially adding to the young core while taking a swing to improve their current roster, essentially having their cake and eating it, too. Wiggins' contract, like Walker's, expires one year before Porzingis'. His defense would help the Mavericks.
Porzingis for John Wall. Wall showed flashes this season but is not nearly the same player he was in his prime. Perhaps Doncic could reinvigorate him. Houston is in the middle of a rebuild, so would likely be intrigued by the chance to swap Wall for the younger Porzingis. Doing so would also create more minutes for their young guards, and possibly, a 2021 lottery pick (Cade Cunningham, in a perfect world). Wall's deal, like the others mentioned, expires a year before Porzingis'.
Porzingis for Kevin Love. Same logic as above. Rebuilding team gets younger. Mavericks shave a year off of the Porzingis deal. This trade has the added benefit of getting Love, who seems to want to contend again, onto a better team.
Porzingis for Steven Adams. The Pelicans just gave up a first-round pick for Adams, so this one is unlikely, but hey, if they want a shooting big man to pair with Zion Williamson, there's some logic to this.
