The warriors do this bc this helps their win now window with curry and butler without giving a lot of future assets like they would need to trade for a bigger name star like Anthoney Davis or Myles Turner, Grant has been a reliable scorer for Portland this year and would be a great number 3 alongside curry and butler, the blazers do it bc they get moody which helps their need for shooting right now and Jonathan kuminga is a young talent that hasn’t performed into a star like he could yet but he could be a good gamble that he could turn into something with more playing time with Portland
