Clippers trade #7 and a 2009 protected 1st rounder to the Sonics for their #4 - presumably, to make sure the Clippers get their choice of Gordon/Westbrook/Bayless. The Sonics, then, are probably targeting Lopez, knowing that they could safely move down and still take him at #7.
Not sure how this affects the Kings. It might result in the Knicks taking Gallinari at #6 if the Clips take Westbrook. Which might lead to the Nets taking a point at #10, which would be bad news for those of us who want Augustin or Bayless.
