Yes. Some people seem to forget where he's coming from. 2 years ago he was playing in Swedens second tier league, Allsvenskan. Then he got hurt in the back and had a long rehab, missed out on the summer training. Missed the first few months of the season. Last year he was playing in the SHL. From there to NHL is a big, giant step. Plus the smaller rink size and another culture. It can overwhelm young people.
Sweden is so different from USA in many ways.
Allsvenskan - run and gun style, not that much structured defensively.
SHL -very defensive, low scoring league. Skate,skate,skate. Play within the system. Team first, structure. No egos allowed.
AHL - the place where nobody wants to play, everyone has the NHL as the goal. Every man for himself, FIGHT if you can't do anything else. Grit first!
