He's underappreciated due to a rough start of the year. I think he was affected by the start of the year the same way Kapanen was. Both good players, but the team was in disarray and that second line was just brutal, especially Dach. It's been two years though that he's shown better play at center than on the wing.
There was also a shift where he spent some time with Anderson and Gallagher. I liked how he was distributing. He might be a good answer to the third line. Dach can take Armia's spot, as in any event, he'll need to be reintegrated slowly to the lineup after the last two years.
