I'll be following Saarelainen this year if he makes it to Finnish league, most likely he will be playing in juniors or in Mestis ( 2nd highest level in Finland). His team KalPa is great place for him to develop, they have a good track record of developing his type of players. Unfortunately they're pretty stacked on offense, so without injuries Saarelainen won't be getting that many chances with them.
On Niko Huuhtanen, I saw maybe 20-30 games from him last year. I think his numbers got a bit inflated by Kovarcik brothers who were dominant players in Liiga. I think he would have potted good amount of points anyway, he is good on PP and has a good shot, but he plays a bit too slow with the puck and takes stupid penalties. He also needs to improve his skating so he can keep up with the intensity of North American games, it will be interesting to see what kind of season he has in the AHL.
