It's ugly, but it's not that far off from what little you can do with this lineup. I would do this:
Goldobin - Horvat - Boeser
Baertschi - Gaudette - Virtanen
Eriksson - Sutter - Roussel
Granlund - Beagle - Motte
With Pettersson out of the lineup and no second-line caliber center, you can't afford to play Baertschi in a complementary role and make Goldobin carry a line. Virtanen has to be on the second line in this scenario, and the only other player who complements his game is Gaudette. As passive as Eriksson has become, he's still a stronger player (particularly defensively) than Granlund. Also, Sutter plays in such a way that playing him in offensive situations not only doesn't improve his production (which will be fine either way), it harms the offensive production of the players around him. Keep him contributing offensively from a shutdown role.
