Unless Fehervary falls apart or someone gets injured I don't really see a big move needed on the blue line. Maybe if they want a depth 7th guy or whatever that's fine.
If they are going to make a big move I think targeting a legit top 6 forward, either center or wing, makes more sense. I know it'd break some brains here but Filip Forsberg would be a perfect target if Nashville decides to move on from him. And everyone else knows my desire for Hertl if Backstrom can't perform at a top 6 level when he returns.
Their defense right now is great, but while the goal-scoring is there the offensive chance generation still leaves a bit to be desired. They're just middle of the pack in that category at 5v5, and for as good as Backstrom has been on the PP chance generation at 5v5 hasn't been his strong suit of late. For a team that has had dreadful scoring depth the past few postseasons I wouldn't mind loading up on a legit top 6 forward to try to help boost that.
