Really makes no sense to me, on either side.
If the Canucks decide to move on from Virtanen...it'd have to be for a young defenceman of similar standing/potential/upside. The Canucks really need the sort of speed and size combo with skill, that Jake brings to the table when he's motivated. To move him, it'd have to be because they're getting an even more needed piece on the back end, that can contribute to the Top-4 on a reasonably priced contract and continue to grow with the young core.
I like Lias Andersson, and i think he's potentially a great "buy low" reclamation project for someone. But he's not the type of player the Canucks need.
And from a Rangers perspective...they already have a ton of sorta big/power wingers. Kreider signed long-term, Kravtsov, Kakko. Plus Gauthier and Buchnevich who are at least big, powerful wingers...even if they're not real "power forwards" in style. Virtanen is really not what the Rangers are potentially lacking for the future.
