I have concerns about the translatability of Salin, to be honest. He's a smaller player; while the NHL has afforded more possibilities for smaller players, there's still the question of how he will be able to fend off bigger and stronger players. So, I don't see him as a defensive stalwart.
Conversely, I don't see individual game-breaking abilities that separates him from other players. He skates well, but no separation speed. No creative/flashy means of puck protection. He's more of a puck distributor instead of one who, himself, can take over a game or can hammer the puck.
Of course, development isn't linear, so things could always change. But I don't see him as regular offensive threat like Kimmo Timonen. I think he'll best thrive utilizing his teammates and just being a complementary piece.
As for a similar game? I dunno. Size, style and position, maybe Victor Mete?
- Sizewise I think he is/will be bigger (and stronger) than Mete (or Avs Samuel Girard or Jordan Spence).
- Salin is Finland's only 04-born d-man, so most likely he will be top 2 dman next year. This year first pair (Vilen-Heimosalmi) gets all pp-time (Vilen 1st pp-QP, Heimosalmi 2nd pp-QP). Next year Salin (and/or Aron Kiviharju) will get his share.
- I think he is having a pretty OK/meh tournament. Against Swiss his play was below average (just like a whole team) and he made one costly mistake, which lead Switzerland's second goal. Against Slovakia and Latvia he was offensively more active and made some good plays and some mistakes - nothing a really good or a really bad. Defensively he has a lot to learn, just like all young d-men.
It's really interesting to see how he does against Team USA and quarterfinals/semifinals/medal games. USA/Canada/Sweden/Czechia has so much more offence/better forwards than Switzerland/Slovakia/Latvia. Next year's tournament (or next season overall) tells better how much he really has propotential.
