Think we should waive Wannamaker and sign JGreen. We have plenty of ballhandlers. With Kemba probably playing 35 minutes a game, we really won't need another pure point guard anyway, unless there's an injury to Kemba. Smart can fill that role capably if need be. Edwards and Hayward also can do it for short times.
If Kemba went down for a long time, we can always bring Waters up, or even sign him to a standard contract and then cut someone else, like Green. Waters is the second best pure point guard on this team!
