When does the season usually end in Sweden? Any chance of him joining the habs or bulldogs at the end of the year like this season? Would he be eligible for the playoffs?
Depends on whether he gets picked for the World Championships or not. The SEL playoffs normally end in mid-to-late April, though I doubt Frölunda have a team capable of going all the way to the final this season.
Barring potential national team commitments he should be able to go to North America sometime in mid-April.
