I see Gaunce as a solid 4th liner with spot duty on the 3rd after cpl of seasons. He will never be a top 6 forward in the NHL and Sutter was right when he said that. Gaunce will get some NHL ice next year but via call up later in the year. Expect Grenier to make the team ahead of G man.
Don't expect Cassels to make the big club next year, perhaps the year after next he'll get a call up but CDC needs to be patient in regards to Cole. Cassels will need 2.5 - 3 seasons of development before being a full time Canucks.
