There's a good chance they are trading Erik Karlsson. And, it could be for prospects, picks and youth. Unless they switch their focus and demand "win now" players in a deal for EK.
Remove Karlsson from the Sens and they are most likely brutal and will be among the favorites to win the Hughes lottery.
The Sabres, Canes and Oilers should be better. Arizona, maybe. I don't see the Sens improving much without Karlsson.
