I don't think there is anyway for certain to know if Anderson would be willing to re-sign in Winnipeg. He is 1 1/2 years out so he can't re-sign yet. Chevy would have to trade for him based on 1 1/2 years of service and hope he likes it in Winnipeg. He only has a 6 team no trade list, so maybe Winnipeg isn't on it.
Swap Heinola for Salo and I think that's probably a deal that Calgary considers. They will get significantly better offers than 1st Yager Heinola. It's a massive risk that you make that move and he doesn't resign. Likely this is an offseason move when you can at least discuss the possibility of an extension with the player.
