Yes, Iggulden tared the league apart the first 20 games or so. Then he got injured, as Systemfel wrote. Ended the season with 34 points (13+21) in 41 games. If healthy he probably would have been a ppg player.
Not seen Himmelfarb play, but from what Ive heard, he's been a important piece in Rogle.
I haven't seen much off Allsvenskan this season but from what I've heard Himelfarb was the best player on his team (Rögle) and one of the best forwards in the league. Rumors have placed him in different SEL-clubs (Mainly Linköping but also Luleå from what I've heard/read.). I wouldn't be surprised if we see him in SEL next season even if Rögle doesn't qualify.
