Rationale:
Trail Blazers:
pick up two promising young bigs in Isaiah Jackson and Jarace Walker (who is on a team-friendly 3-year deal) who fit well into their rebuild plans
pick up three decent vets whose contracts will expire next year, freeing up to $65.9 million of cap, in Simmons, Schoder, and Adams (which would take them from -$30M to appx. +$30M)
shed $3.6 M in cap space
Rockets:
make room for whichever of the two generational PG talents who'll be the best player available for their #3 pick (Stephon Castle or Nikola Topic, both of whom are ready to start right away)
pick up an elite 3-level scorer and starting PG/SG material in Simons, who is not much of a drop-off from VanFleet when you consider he's $17M cheaper
pick up elite wing defender Thybulle to shore up defense
pick up Rayan Rupert, an athletic French guard from last year's draft with potential
shed $16.6 M in cap
Pacers:
pick up big Deandre Ayton to add depth, defense, and NBA Finals experience at the center position
Nets:
upgrade Ben Simmons into Fred VanFleet
get the 2023 6th man of the year in Brogdon
Notes:
I just added some random picks to the trades to make it feel like it made more sense, but feel free to suggest other options.
