Vancouver is likely looking to save cap, not salary. Russell is very tradeable, but to a team who needs to save real cash, and can/wants to absorb extra cap space.
Having said that, the Oilers would want Sutter.
I'd suggest Jujhar Khaira. Emerging as our 4c, but we could try Haas there. Big, and physical. He's from Surrey, so I think Vancouver would like it. He has a low cap hit and is RFA in 2021. The Oilers like him too though. I think with retention on Sutter it would be done.
The other potential player to trade is Chiasson, 1 year left at 2.1 AAV. Good hands, good net presence, smart bottom sixer. No retention on Sutter for that one.
Of course if you are itching for Kassian back that can be arranged
