NHL.com has a serviceable list of the top 30 remaining UFAs. http://www.nhl.com/ice/news.htm?id=637078

Niklas Hagman: Seems to always be a Cane killer and is a Finn. Could he fit in?

Dominic Moore: Another 3rd line Center possibility and oft thorn in the Canes side

Mike Knuble: A one year deal for this guy does not seem like such a stupid idea to me.

I left out the obvious wait and see scenarios with Doan and Semin. Interesting that the need for a solid D-man is not being mentioned by the press.
