Yeah, the team as currently constituted doesn't have room for more 2/3s. I know it isn't much, but I don't see how Ainge can justify to Wyc and company bringing in someone at a million or so (which turns into 2 million) when they already have Giddens, Walker, and Allen on the roster. Plus, unless someone gets hurt, whoever we did pick up probably wouldn't play anyway.
I think if the 15th roster spot is going to any FA, it's going to go to someone like Bobby Jackson, who will sure up the backup PG spot.
