Considering the cap crunch the Leafs are in, I would consider Liljegren pretty invaluable considering his ELC deal and his potential. If the Leafs were to include him a deal, they would need to be getting more back then simply Kuemper (retaining salary or not). If the Leafs could figure out a deal that would include Kuemper, Garland, Crouse and Dvorak, that would be pretty special but I would hate to see the assets the Leafs would have to give up to do it. As far as your deal though, I would say Dermott is way more expendable plus a 2nd should do it for Kuemper.
