As a Raleigh Native I follow the canes like an older brother keeps tags on his younger more annoying sibling.
That said, The canes are doing alright for themselves and as such probably won't swap strength for strength. The typical way Carolina does business is they throw prospects at people (they're TERRIBLE at drafting skinner and faulk not withstanding) for a ufa or a cast off player.
I can see Carolina going after a teams struggling forward with some reclamation project prospect they have. For example, they're more likely to go after Lenio and throw some cheap prospects buffalo's way as UFA's typically don't see carolina as a first choice.
They are one of my favorite teams right now. Doing very well for themselves. We'd want a D piece we can use now, and your right they probably wouldn't wanna give that up right now. There D would take a big hit.
I noticed that they seem to draft nothing but Plymouth Whalers. Karmanos owns both teams so I understand why they do it, but that's a terrible strategy IMO.
