Makes a ton of sense if they're done with Andersen and are picking up Murray. Pitt gets a good young forward and gets rid of their goalie problem without adding a ton of salary or giving up future assets they need to rebuild. Sure they miss out on a "futures" package for Murray and are selling him at a low point, but it was going to be hard to get picks and prospects for him in such a cap constrained environment.
Toronto finds a new #1 and potentially sheds some salary in doing so if he signs cheaply enough.. Kapanen isn't too expensive a price to "upgrade" from Andersen to Murray. As long as the Leafs have a spot for Andersen, I fully approve. Theoretically, Andersen shouldn't be TOO hard to move since his salary is only 1M (even if his cap hit is high), I just don't see the Leafs getting assets for him. Hopefully they don't have to give up anything significant to move Andersen because there are some legitimate concerns with Murray and if Andersen outperforms him next year they would have effectively gave up "Kapanen +" to downgrade the position. In such a case, management is going to look pretty foolish.
