Harden needs to commit to staying with Sixers for this plan to proceed.
For the Sixers, Siakam's shared nationality with Embiid would make him a great addition as the third star, and Gary Trent would make a strong starting shooter.
Mavericks could benefit from bolstering their defense and shedding bad contracts ahead of schedule.
Raptors would acquire a third young star alongside Barnes and OG in Maxey, as well as a lottery pick and the valuable 2029 pick through Sixers' all-in move.
Starting 5: Harden - Trent - McDaniels - Siakam - Embiid
Second Unit: Melton - Springer - House - Ninang - Reed
