One of Nylander and Forsberg as well as Landeskog on the first line instead of the wingers you suggested

Arvidsson and Rakell has had clear downward form trends last couple of years, Arvidsson struggling with injury. Same with Erik Karlsson. Problem is players struggling with injuries seem to have trouble finding their game again. Not sure Pettersson does as well in the left wing as the right wing, the spot he played his first year before teansitioning to center in Van if I remember correctly. However, if he did, Hörnqvist could perhaps be an interesting player with Zib and him. If Rakell finds his form, that third line looks interesting, of course. In the powerplay, Nylander successfully played PP on the left side in Toronto in the playoffs, an interesting option if Pettersson is there. I am glad you didn’t put Pettersson and Nylander on the same line as they struggled together in the WC before the coach split them.
