I just want to point this out and I agree with Vznla81 that there is little to be had next year via FA's outside of EJ. No superstars are coming IMo.
The kicker is a trade and a few guys will be expiring deals (2012/13) that won't likely come back to their team hence a trade could work in our favor.
A look at a few.... Paul Milsap, Josh Smith, Jameer Nelson (PO), Gerald Wallace (PO), Kevin Martin (Maybe), Elton Brand, Al Jefferson, Ellis (PO).
These aren't world better but teams will be looking to resign some of them or let them go through a trade if they think they can't resign them.
