There are lots and lots of ways to make the salaries work. Bass gets mentioned a lot because he is the most expendable player in the event that we do trade for Smith, and because his $6M gets you half way there. After December 15 we can mix and match Bass, Green, Milicic, Lee, Terry, and Rondo to come up with tons of deals that work on paper. Play with the espn trade machine.
I'm betting none of those are contracts that the Hawks actually want, though (except for Rondo's). If I was Atlanta I would want young, cheap, players with lots of promise. I don't mind bringing Bass on, but what I really want is Sullinger and Bradley.
