I think both teams are in the same situation. Will be tough to move Ward and his contract and will be tough to move VL with his contract. That's probably why the two teams are "reportedly" talking.
Philly needs cap space though as they are only about $2M under the cap with players yet to sign (plus another ~$5M in space for Pronger on LTIR) if I am reading Capgeek correctly. I'm sure that's why there is the request for the Canes to retain some salary (for Cap reasons, not salary reasons) and at least be cap neutral, while filling their back-up goalie opening.
I'm not for this deal as I don't like the length of Vinny's deal, but if somehow they could sweeten the pot a bit (Picks, prospects, player, etc...) it might make it more tolerable.
