I don't feel like it's necessary for Kotkaniemi to be in the NHL right now. He obviously lacks strength and falls down quite often. The skills are there and he has nice speed but I can't see him producing that much, especially as the games will get tougher in the later part of the year.
I would not send him back to Finland. He's been in NA for a month now and improving. Laval should be his next stop. From what I have seen, he should be a point per game player right now in the AHL. The Habs are gonna lose anyway, and Laval looks good. Might as well just go down there, dominate and maybe win a championship.
He has a taste of the NHL now. I feel like as soon as next season, after a summer of working out, he could score 50+ pts. He will be stronger and faster. A breakout should be in the cards. He has everything it takes. But this season should be about development.
