Houston's water is obviously poisoned because no sane person would trade Rudy Gay after getting him when you should have never had a chance. Stupidity.
That said, they should be looking to get Cato through FA, he fits nicely and covers Yao's weaknesses well, can play both C and PF also. Melvin Ely is another guy they should be looking at. Mike James isnt needed. Alston, Wesley, Sura and Head is a good enough PG/SG combo when you consider that Battier and Tmac also can both handle the ball for extensive periods.
