What worries me about Chicago is that Bjork is exactly the type of player they absolutely need have, so they'll be a threat up until the minute he signs somewhere. They're so top-heavy with Kane/Toews/Hossa/Keith/Seabrook/Crawford and now Panarin that they've got to be desperate for ultra-cheap, seemingly NHL-ready talent like Bjork.
Flip side is if you're Bjork or any other FA, can you see yourself having a future there? There's no way that team can afford another contract over like 4 million a year, so what happens when his ELC is over? If they've got to move guys to make the money work, will they even be all that good of a team anymore when they're struggling now?
I still don't see any reason Bjork wouldn't be interested in signing with Boston, unless he's absolutely got his heart set on Chicago. At that point we'd just have to hope he lets us know soon enough to get something for him. I still think he gets his WC experience now (putting him in line for an Olympic roster spot), goes to ND to finish his degree and compete for a National Championship, maybe grabs an Olympic medal and then signs with us in the spring after a hell of year.
