The Spurs waived Darius Washington today and promptly signed Keith Langford. This was after resigning Marcus Williams earlier in the week. With Barry out for two weeks and Gino on the shelf as well the Spurs have stocked up on stop SGs / SFs. They'll have a couple games to see what they have before contracts become official on January 10th. It's doubtful the Spurs will keep both Langford and Williams on the roster due to luxury cap penalties.
