Can teams amnesty someone signed post CBA? never knew that.
I'd personally trade Green in a heart beat if it meant making the team better.
e.g. Bass, Green, AB for elite SF and better backup C
KG, Wilcox, SF, Lee, Rondo
+ New Center, Sully (I'm assuming he's gonna be good), Pierce (assuming he agrees to come off bench), and JET off the bench.
Just would be a much better team, I don't think anyone (player or agent) could be mad.
