The problem with this is do Gryz or Forbort have any value. I feel Gryz would have been moved long ago if he had any value .Agree, I would not mind Middleton on the team, but no way he cost you Carlo who is vastly better, if you said for Gryz or Forbort, ok maybe.
Carlo is not a D-man the Bruins should consider moving .
Gryz on the other hand. I feel would be moved quickly if there was a market for him . How valuable is 3,687,500 of cap space ? This is the problem IMO with trying to move him, his cap space is more valuable than Gryz is as a player.
