I think this is one of the most win-win trades in the NBA right now. Pistons get an all-star caliber player who has championship experience and will improve their frontcourt by replacing Stewart as the starting power forward, and the Mavs get two future first rounders, a front court for years to come with Flagg, Stewart and Lively, and are also able to evaluate what they can get from Harris and Sasser.
Rotations:
Pistons:
Cade, Ivey, Robinson, Davis, Duren
Jenkins, LeVert, Thompson, Holland, Reed
Mavs:
Irving, Christie, Flagg, Stewart, Lively
Williams, Thompson, Marshall, Harris, Cissé
