Chris Mannix tweets that it is official. More to come...
UPDATE:
Neither David Aldridge nor J.A. Adande reference a buyout with the Celtics. They both say Wallace is walking away from $12-$13 million dollars. I thought a buyout was in the Celtics best salary cap interests?
We're also wondering if Sheed actually filed the paper work today.. or did he just let everyone know today and give Danny the heads up so he can make a trade?
