Did you, by any chance, get to see our other Finn, Lenni Killinen, play this year?
This year I have been watching more NHL and Hurricanes games than Liiga games. Additionally, Killinen plays for my team's rival team Ässät.
I took a quick look at some Finnish news sources and message boards (local hfboards equivalent) so all of this is based on second hand knowledge and stats.
3+8=11 points in 32 games seems decent for a young rookie. However, upon closer inspection he had 1+3=4 points after his first 9 games meaning he cooled down a bit later in the season. He also had an injury in the middle of the season which could explain slowing down. He was -4 but that's actually quite decent since his team was worst in the league. Average playing time was 13:20 which surprised me as I think he was playing in bottom-6 and mainly in the 4th line.
The consensus regarding him seems to be that he's smart and versatile player. He's considered to be quite raw and the expectation is that this year was just to get experience and next year he could gain some opportunities in a more scoring role. Finnish Liiga is old-man's league and young players usually take a while to get going (unless you are exception like Barkov, Laine, Aho, Pulju, Rantanen etc.).
My guess is that next year he could do some damage at the Liiga. I believe he's at least one, more likely two full seasons away from coming potentially to North America (where at least 1 or 2 AHL seasons will take place). As a 4th rounder, I think he has progressed as he managed to get regular playing time in Liiga as opposed to juniors where he played last season.
