Hawks don't have anybody worthwhile to have a firesale on.
Realistically, the only players that Hawks would want to move, and might be in demand are:
Zhamnov & Daze are both out with back surgeries, so no one is going to pony up substantial assets for either. Even when Zhamnov get's back (should be soon I think), he's due to be a UFA after this season which will limit his market value. Daze's coming off his THIRD back surgury, so his value is basically squat.
Only guy that a contender might want is Sullivan, and he's not a guy that a team is likely to look at and say "he's a guy that will help us in the play-off's".
The other guys that people are talking about (Ruutu, Bell, Calder, Arnason, etc) are the guys that the Hawks shouldn't be moving.
