The Blazers get the 34th pick, while the Warriors get the 44th pick and cash.
Whenever cash is the only reason for trading down in the draft, trouble is coming. Clearly Chris Cohan is determined to squeeze the Warriors as dry as he can before he dumps the mess on someone else.
Considering the depth of this draft, the Warriors could have gotten a solid rotation player with the 34th. The chances of doing so with the 44th are that much lower.
