I expect kg and Paul back for one more year. I don't think this is the time to try to trade rondo, ab, green or sully they all need to be given a chance to at least improve their value next season.
I would
1. Trade bass, terry, melo for bargnani
2. Sign Dejuan Blair to mini mid level 3yr 3 mill
2013-2014
Guards
Rondo, ab, lee Crawford,
Forward
Pierce, green, Williams
Bigs
Kg, bargs, sully, Blair Slav
