Clev trades big Z to Houston for Battier, Cook and Berry.
Battier helps their pick and roll defense. He is a winner. He can hit the outside shot. Cook and Berry, while ok roll players, also represent two expiring contracts they can use later with say, West, to get a player earning close to 10 million a year.
For Houston, they get a one year C and 10 million off the cap next season when Yao might return. There location makes them always attractive to FA.
