Every team gets what they want

Why do the Warriors do this? For Defense. Warriors are terrible on defense this year but amazing on offense so adding these 3 assets will help with the defense on the team also on the offenseive side. Also helps them let Wiggins go whos been terrible on Offense this year. (Besides Seth Curry hes here to replace moody and also being reunited with his brother ofc).

Why do the Mavs Do this Trade? Same Reason as GSW , Even though Wiggins has been unreliable on offense his defensive Game is still good and this is what the Mavs are looking for , Defense will help this team out alot due to not needing to much offense and also due to the Mavs having kyrie and luka and THJ already Providing much offense but when Wiggins is Hot he could help out on offense aswell with Corey Joseph who has shown flashes of good shooting these past few games.

Why do the Jazz do this Trade? Mainly For the 1st Rd Pick Pick and a Young Asset in Moody who has shown potential of being 10+ PPG scorer when Giving Min (Maxi Is just to match Contracts).
