This is a little late but I thought it was a good article about 2009's free agency. Interesting tidbit about the Hawks:
"The Atlanta Hawks could clear enough cap space for a player at or near the max, but it would take letting both Mike Bibby and Marvin Williams walk and renouncing the rights to Josh Childress."
Marvin Williams or Josh Childress? I like! Or how about Felton, Morrison or the poetry of McCants? (all have might be let go to clear cap room).
