This was the best I could do:
Kupari: CF% 46.3 which was below his team’s 53%.
Kotkaniemi: CF% 49.7 which was above his team’s 47.6.
Basically it looks like Ässät did better in controlling play with Kotkaniemi on the ice than Karpat did with Kupari. It’s not a huge gap, but for stat nerds like me, it is a bit of a difference.
If I am reading the site correctly, I believe Kupari had 52.5% of his starts in the oZone. Kotkaniemi was 49.2%, so he gets slightly more defensive assignments.
All the stats are on the Liiga site.

I don’t want to mislead anyone as there is a lot more to stats, even advanced stats, when comparing players but it looks like Kotkaniemi had better advanced stats (plus, I don’t read the language so I didn’t list everything here like Fenwick, PDO and others), while scoring more points while playing on a much weaker team. There’s probably a half dozen ways to interpret that, but I think statisticallyit favors Kotkaniemi.
