I think this trade makes sense for all parties assuming the raptors blow it up

Pels gain OG which improves their perimeter defence and provides them a player who impacts the game without a high ball usage %. Losing Trey kinda makes sense in my eyes for the Pels - Though he's an amazing player his contract is coming up for an extension and he virtually plays the same role as Herb (and BI & Zion). So having so much money tied up in forwards could be a negative for them.

Raptors gain a young PG/SG for the rebuild as well as 3 FRP.

Warriors move Wiggin, who's been struggling as well as Moody & Kuminga. Thought Kuminga has been starting, Moody isn't getting a lot of play time & Wiggins is benched. They replace those 2 with Bojan who's definitely a starter and would provide some great mid range scoring for the Warriors. He can do so without a high usage rate as well which aligns with the Warriors existing core. They also gain depth at the forward position.

Pistons gain heaps of young talent but also some older vet pieces to try and lead the team. I imagine if this happened the starting 5 would look something like

C: Duren PF: Trey SF: Thompson SG: Moody/Hawkins PG: Cade

Bench: Wiggins, Schroder, Nance, Kuminga, Hawkins/Moody, Stewart, Hayes, Bagley & Wiseman
