It's nearly impossible to predict next seasons roster. Until Benning deals with the extra glut of forwards, there is no way of telling who will be the odd man out on this roster.
Eriksson is obviously a player who needs a change of scenery. I'm sure Benning is looking to deal him, but it's a daunting task. Until Benning finds a taker, Eriksson unfortunately will most likely still be on the roster next season.
Sven Baertschi is another big question mark. It is unclear if Sven has completely recovered from his injuries, he is one concussion away from retirement. Hopefully "Bear" can avoid being on the IR this year. If he can stay healthy, he will easily be penciled in on the second or third line.
Sutter who was once considered a "foundational piece", is holding up Adam Gaudette's roster position. This one dimensional player is probably on the market, but lacking interest from other teams due to injuries, and a over priced contract. Unfortunately I do not see Gaudette on the roster next year, with Sutter still on the team.
Adam Gaudette, as I said above, will probably be pushed down on the depth chart and starting in Utica. As much as I want to see him penciled in on the third line center position, it might be a good idea to give him some time in Utica to find his offensive instincts. Gaudette for the most part has been unimpressive this far with the Canucks. Until Sutter is dealt, I really don't see him making the roster. Playing huge minutes in Utica, may not be a bad thing.
When Roussel comes off the IR, I see the forward roster kinda looking like this,
Ferland Pettersson Boeser
Pearson Horvat Miller
Roussel Sutter Baertschi
Leivo Beagle Virtanen
Motte (Eriksson)
^Roll all four lines
