I'm not saying it's not possible but Salomäki really needs to explode in order to make the WC national team this year. The team will probably be very stacked since alot of NHL players will be wanting to play in the home games. I'm happy if he gets to play some EHT games and see how he looks. And to his spot as a 4th line crash and banger there already is Komarov who is still definately better than Salomäki.
In my opinion Pulkkinen should be the next in line, not Salomäki. Of course anything can happen, but he's still quite far away from making the team.
Pulkkinen is useless in bottom 6 lines and were pretty stacked on top 6. Salomäki is versatile and can play all situations. I'm very disappointed about Pulus developement. His two-way game isn't any better from last seasons. His work ethic isn't very good. Just waits for puck etc... Salomäki is ahead him IMO. Statswise They're even this year but Salomäki adds more into table. If i had to choose from these 2 i would choose Salomäki hands down.
