Depends on what you mean by deep. Scoring wise, probably not however the Fjällby - Davidsson - Zetterlund line has looked really good in my oppinion and i wouldn't be suprised if they score more points than expected.
Again it's no surprise. Fjällby and Davidsson are playing together in the SHL and they usually end upp spinning around in the offensive zone for quite some time. Add Söderlund or Boqvist and it's a great second line that will put up points. They can really dominate games
