suter, burns, and Regehr are the most likely to move IMO. Yandle has a chance. Jackman perhaps. A dman from washington may move to any of green, wideman, or even schultz or poti. There are also a good handful of UFA's, though noone in the super top tier.
However, its pretty unpredictable every year. I didnt see both richards and carter getting moved (one or the other maybe, but not both). Dougie will get someone on D, whether we are satisfied with whatever he does remains to be seen, but we'll see!
