The Warriors get an all-star and the Raptors get picks and a young center of the future.
On offense dray is the defacto PG for the Warriors and you can never have too much length on defense so their would be no problem with a Curry, Poole/Klay, Siakam, Green, Boucher starting lineup especially considering how good Boucher is from deep. The dubs also don’t completely sacrifice their future as they keep Kuminga and Moody.
The Raptors get Wiseman who can pair nicely with Barnes for the next decade+ as well as a first and second next year and a future first and second. Barnes, FVV, Wiggins, OG, Wiseman
