According to Marc Stein of ESPN

The Kings, sources say, are open to moving big man Samuel Dalembert during the next 27 days before the deadline, but they remain unwilling to take back anything other than expiring contracts to preserve maximum flexibility on the other side of a new collective bargaining agreement ... unless someone wants to donate a star. With Dalembert possessing an expiring contract valued at $13.4 million, it's not easy to find a match that keeps the Kings in the same cap position as they are now.

So would you trade Yao's insured contract for Dalembert, Landry and 2nd Round Pick?

THis gives the Rockets a good look to see if Dalembert is a good fit with the Rockets, and lets them know how our current players produce with a decent big man in the middle. Landry can be kept and lets the Rockets move Hill or some other PF in a future trade.
