I wouldn't say that Henriksson is playing on the top-6, if you consider his linemates. The way that Frölunda lists their lines says pretty much nothing. In the official
game report, the Hjalmarsson-Mursak-Raymond line is listed as the 4th line while it's the obviously most skilled and offensively potent line.
With that said he did play 6th most of Frölunda's forwards in the opening game. He didn't play on the PP (and I don't expect him to do that, at least to begin the season) but he played 3rd most on the PK among forwards.
5 on 5 only Max Friberg played more.
