Mavs make the trade to get better and make sure get good return for their main role players. Mavs send DFS+Wood+McGee for Beasley+Vanderbilt+Sexton. Jazz get top5 3&D player in the league as well as Wood who's a significant scoring Big with McGee as a vet.

Mavs send THJ+2SRP for Hield to add that shooting with Vanderbilt.

They trade Sexton+Bertans+Protected FRP for Bogdanovic+Burks

Mavs send Reggie+SRP for Plumlee as the Rebounding Big with great Playmaking ability when Luka gets doubled

Mavs lineup: Luka-Buddy-Bogdanovic-Vanderbilt-Plumlee Burks-Spencer-Green-Beasley-Maxi/DP

Mavs have significant better roster without giving up their core of Luka-Spencer-Green and would add more younger guys without giving up significant draft assets to make the move for that 2nd star if required but I think this team goes to WCF ngl.
