I think that Swedish meatball line can configure in a multitude of ways. Gustafsson on LW, AJF at RW, or more naturally Gustafsson at C, and Stenlund at RW. He may have had a bad game at LW, after setting up a goal on his first shift in that position against Vancouver. But that's far from conclusive about the player. The one thing I notice from a defensive minded perspective is that taking Gustafsson off the PK with Lowry and Stenlund usually starting the 1st shift, where there are no weakness on the faceoffs now, is that there is no second centre to back those 2 up. So I wonder if the units get reconfigured, or if somebody else like Scheifele gets some time on the PK. I still see Gus getting back in the lineup, I think it's just hard to bench Gagner after he gets a GWG for his team. And Tampa isn't a team that is particularly fast in their bottom lines.
As for Heinola I am not sure that Samberg gets taken out of the lineup for him, you definitely don't want Josh playing significant minutes on the PK if he is banged up, but having 8 defensemen can allow you to sit one who is maybe injured but playing through it. I think the door is also open for putting him in 7 d alignment.
It's sure nice to see a semblance of a regular lineup. The one guy I think who still has to prove something is Kuhlman in the checking line role. That's Appleton's spot, and probably Maenalanen's when he gets back.
