Next year's lineup is almost set:
Backup PF/C: Griffin, Willis
Backup SF: Morris
Houston needs a starting C and backup G. ("Are we talking about the Rockets or Comets?") I would be surprised and disappointed if a combination of Cato (size), Thomas (undersized talent), Williams (salary), and/or Norris cannot be traded for one of the following (little-known, but reliable) centers:
Brad Miller (Chicago) - Chicago is going nowhere and this would be a good opportunity to give Chandler and Curry more court time.
Vladimir Stepania (Miami) - Miami could potentially make room to sign free agents in the offseason. Miami will have to regroup through free agency (and trades).
Zeljko Rebraca (Detroit) - What would it really cost Houston to trade for Rebraca?
Steven Hunter (Orlando) - (Hunter's movement with the ball reminds me of Thorpe and Tim Perry.)
University (Haven't we done this before?) Blue
