According to hoopshype, Houston's payroll in 2010 is the following:
Yao Ming: $17.6 million
Shane Battier: $7.4 million
Carl Landry: $3 million
Sucky Hayes: $2.3 million (Team Option)
Aaron Brooks: $2 million (Team Option)
Joey Dorsey: $900,000 (Team Option)
Assuming we keep Hayes, Brooks and Dorsey,
TOTAL: ~ $28 million
Since the cap will be set near $60 million, it gives us room for another max contract.

So, who are our likely targets in 2010?
Here's a list of players who will be FAs in 2010.
