I don't think its a tough choice. Its an obvious choice. Keep Washington. He didn't fill up the box score last night, but he had four rebounds, three assists, and the most important stat, NO TURNOVERS in those sixteen minutes. Do what you got to do to keep him. You're not going to have a true backup PG if you let him go in the beginning of the season because of the injuries to Beno and Vaughn.
Either cut Williams and swallow your pride or do us all a favor and cut Beno and fork over some cash by doing that.
