Actually I like this better:
WAS Gets: A. Aminu, M. Leonard, POR 2nd
SAC Gets: M. Harkless, POR 2nd
POR Gets: O. Porter Jr, S. Labissiere, Jason Smith
Washington saves $13M to duck under the luxury tax (creating a $13M trade exception for the summer), clears room for Oubre to start, and gets a solid Forward back in Aminu.
Sacremento needs SF help. They have too many good bigs (believe it or not). Harkless is still youngish, and they look somewhat competitive and dint have their pick this year. They have the cap room to make this deal.
Portland gets their starting SF whos a good small-ball 4, an Aminu replacement that can play PF or C, and clear the path for Collins to start.
