Now my 2nd and last post for now. I see a lot of similarities with the way things went in his last (and only full) FEL season. I don't have a crystall ball, but because of this I do see a reason for some optimism.
He played in Kärpät and the head coach was Lauri Marjamäki, who then went on to the national team and after it to Jokerit Helsinki (KHL). Marjamäki made Kärpät play a pretty boring, defensive oriented game, where the system played a big part. Until Christmas Puljujarvi filled his role very well, but his production and offensive output was a disappointment. At that time he was according to some even challenging Matthews, so the expectations were high. I think it was mainly Puljujarvi pleasing the coach and thus concentrating on the defensive side of the game, but maybe also the pressure from not producing as expected. The passive team system may have played a part too.
Then he played the incredible WJC and he was suddenly like a new boy in the FEL. He was easily one of the best players in the regular season and the playoffs, scoring the 2nd highest points. He did have some raw aspects, but it seemed his high confidence masked them well most of the time.
He's dominated at every junior level and flashed in the NHL at the age of 19. For me it's rather a waiting game at the moment and I hope the path with Hitchcock will go as it went with Marjamäki in the FEL. I think there are some similarities, but we'll find out more within these coming weeks and months. I hope the combination of him getting braver, more confident (a couple of goals should help the most) and receiving more TOI and PP time will eventually do the trick.
