I actually saw Herranen playing last weekend. The game was between He-ki and Jyki and the game ended up something like 8-1. The whole Jyki team was awful! Herranen was easy to recognize because he was the smallest and chuppiest kid in the rink. He was slow and didnt do anything special. It was kinda interesting that Herranen was the captain of Jyki, I mean he's four years younger than the oldest kids in that league
Possibly a younger brother of Joonas Nättinen? Slim chance. There seems to be a lot of Nättinens from the Jyväskylä area who play hockey
He's the younger brother of Jussi and Joonas Nättinen. Apparently he's also a cousin to Topi Nättinen.
He played centre forward in a game that I saw recently, strong in the face-offs like his older brother Joonas. Nice skill level and overall a good player for his age. Will be interesting to see how he develops in the future.
