I don't think there is really any chance that Blacker makes the team next year. I think Holzer has a chance to be the 7th defenseman, but I don't think Burke will go into the season with him as a lock for the top-6.
Unless somebody offers something miles ahead of the current value, I don't think Burke trades Phaneuf, Liles, Schenn or Gardiner. They have all been identified as part of our core going forward.
I think one of Komisarek, Gunnarsson or Franson wil be traded this off-season, and if we sign Schultz (you don't pass on a player like that if the opportunity arises), maybe another one of those players goes (though remember that Burke likes to go into the season with 8 defensemen). I think if we don't sign Schultz, Komisarek goes. If we do sign Schultz, Franson goes.
