He has become a star in the SHL--63 points in 69 games between this season and last, including 10 points in 14 playoff games--playing for Rogle, which is Adam Edstrom's team (also Oliver Tarnstrom). Not totally surprising as he has always had good puck skills and a fantastic shot.
His problem, as I remember him from Hartford, was that he was a guy who thrived on finding the soft spots in the defense to unleash his shot when he was in juniors, but he never could really do that in the AHL. He was a bigger guy but not very strong, and so he couldn't really fight through traffic to find those open areas that he needed to be successful. So, naturally, a move to a league that's less-physical with more space on the larger ice surface led him to thrive. Ryan Gropp, who is also in Sweden right now, had the same issues. Gropp was stronger and went to the net better but still had issues with finding the open areas. And he also didn't have Mat Barzal to pass him the puck in Hartford.
