Also from the handful of times I've seen him, he looked like a good 2-way player with above average IQ. I think even if he doesn't become an offensive force he still becomes a solid NHLer.
I gotta be honest: I don't think you watched close enough or else you just don't understand 2-way hockey and hockey-IQ.
From is absolutely not a good defensive forward and in no way does he have a high hockey-IQ.
He is all flash.
He is absolutely skilled on both his skates and has smooth hands and likes to challenge a whole lot. He just isn't very good at things including team mates. It's not, that he won't pass the puck, he just doesn't read plays well and thereby isn't able to play a high quality passing game.
He is working well, though. Especially with the puck, where he will try to beat opponents one-on-one quite a few times each game, once he feels comfortable. I guess in the first game or two he might be a bit nervous and respectful in new surroundings and hence be passing the puck more and leave it to others to do the challenging. But once he feels comefortable and perhaps also pressured to show something, he will start challenging. It will be nervewrecking and will lead to a lot of unnecessary puck losses and turnovers. That's what happened in Sweden.
On defense he will absolutely work hard with his fast and very technical skating, but he will also be out of position a lot in his work, leaving opponents open. This due to his low hockey IQ.
He is all flash.
