Pretty sure Seattle has zero interest or even the cap space for Vic, even at 50%.
They have a glut of scoring wingers and were fine letting Sprong and Donato walk because they still had McCann, Eberle, Burakovski, Schwartz, Tolvanen and Bjorkstrand.
They also have some young wingers they are excited to see get some icetime should injuries arise.
What Seattle really needs is a playmaking center. Wennberg's skillset is just not a very good fit, and Beniers is young and inconsistent, and at 20 years old, could probably benefit from some insulating - he just isn't a number one center... Yet.
