The full deal includes the Kings sending out a conditional second round pick to the Celtics for Sam Cassell and cash considerations. It is believed that the Kings will use the cash to waive Sam Cassell and the second round pick will never be seen by the Celtics due to its heavy protection.
The Celtics now free up a roster spot, which a league source believes will be used to add a player before the post season begins. Cassell hadn't played a single minute for Boston, but was believed to be a veteran presence in the locker room.
Similar moves like this have been made to aide a team from nearing the luxury tax or having to pay a guaranteed contract for an unneeded player. The Los Angeles Clippers have been the most active in situations such as this, most recently with the acquisition of Detroit Piston guard, Alex Acker.
