Terrence Williams' 10 day contract was up tonight after the game vs the Warriors. Danny had the choice to sign him to a second 10 day contract, release him, or sign him for the rest of the season. Wojo has reported on Twitter that T-Will has impressed enough in his first 10 day contract to be rewarded with a contract for the remainder of the season, and possibly for next year as well.
