Sixers- get AD to upgrade both defense and offense, defense they can rely on AD to close out them Embid can stay at paint, offense Embid have the influence in the paint as prime , but AD can recreate this advantage
Mavs- receiver the trash contract but also get several valuable picks to rebuild with cooper, also get McCain a young player as their point guard
Edit- this trade still could work Mavs send a player to Nets to lower below second apron and Sixers pay a second
