Two games of Helenius shift by shift video
Three more games of Helenius
From my 3rd tier of top 9-12 players Helenius is the hardest to project what kind of future he will face in NHL.
He is annoying to play against, he is taking away the puck regularly, he is patrolling the zones, he is moving a lot, he is positional player and forechecking player... but still he isnt the first forechecker on his squad often. I saw moments where he is watching and controling his player but he is separating from him and making dangerous shot. But in other moments he is doing exactly what you are asking for from your defensive forward.
Helenius is very good passer and he has good playmaking skills. He is controlling the puck, trying to force opponents and making a pass in the moment when his partner is open.
He has good shot, good skating and very good speed.
Issues with Helenius is his lack of high end skills. Its not that hard to understand that some part of his success is on the shoulders of slower game in Liiga. On the other hand everything he is doing - very competitive game, always in the pace of the game - against men. Yeah, I know its a meme, especially for Liiga and its kind of a true, but still competition is on the another level than most junior leagues. OHL is no more physical than it was anymore and players dont have real examination of their skill. Liiga is physical and even if Helenius is making a lot from the perimeter, he is driving dangerous zone, challenging defensemen, creating space.
The question is where his real ceiling in NHL? Second line two way center? Top-6 two way winger? Its questionable because we dont know how far he will go with his development. He isnt Aho with his skills, but he can develop some of his skills. He is very hard working player but he isnt physically gifted. But he is smart and he is involving in the pace of the game. He is doing great in play off - he looks like one of the best player of Jukurit. And if he will add much more accuracy to his game(I think its the biggest issue and its okay for junior player in the men league), he can be very good NHL center. He is top-4 productive player from his age in the last 15 years in Liiga.
If he will not develop his skills to the better levels, he should be very good two way complimentary winger. Some kind of Haula.
Reason why I put him below Chernyshov and Nygard is his lack of high end skill set and lack of physicals. Chernyshov and Nygard needs less to develop to be better. And their physical tools give them more to hit their ceiling. On the Helenius side is his center game where he is very good enough in the league. But he needs a lot to do to be NHL top-6 center. Still like him more as potential NHL center than Catton.
