General Manager Brian Burke has put Tomas Kaberle on the trade block. He sent a letter explaining to the other 29 GMs that Kaberle can be traded without his consent.
Many GMs may have been hesitant before because Kaberle only has one year left on that cap-friendly deal but now they need good players for this season so the offers will be a bit more. The teams that missed out on the big name free agent defencemen are probably the ones who will go after Kaberle the hardest.
How did I come up with this list of teams? I looked for holes teams had and also teams losing defencemen to trade, free agency or retirement. I put more weight on the teams that tried to re-sign their defencemen instead of the ones that traded their rights.
