He's a really good playmaker, absolutely playmaker first which you might not see from the highlight package. But look at his WC play, creates chances for Möller all the time. And I mean he was waaaay better than linemate Backlund (NHL regular) and Nyquist (NHL high producing player) through the tournament. In the game against russia (semi-final) he was easily the most notably good player on the ice, over-shadowed Ovechkin and Malkin by far in that particular game.
Of course he isn't near their quality, but the upside is really high. And he also has a great, super-accurate shot both slapper and wrister.
Downside: Is pretty dependent on a top6 role, playing rightwing with a skilled preferably sniper playmate and someone who drives the net. Needs to play the playmaker role on the right side on the PP, but he's excellent there. With the role he got in Colorado, playing with non-physical linemates and the such, I don't think he'll be very good.
But now he's waaaay better than he's ever been before in the SHL, way better than when he went to Colorado, I mean previously up until last season he wasn't even really close to the national squad, now he played the first line and was indisputably the best player on the bronze squad. The development this season in the SHL/national team has been pretty sick, he's gone from "pretty good, high offensive upside" to "dominating".
Edit: And it's a no lose situation. If he can't be good at the NHL level, he'll break the contract and go home to Sweden (which I'm hoping for since he's on my particular team). And it won't cost you a dime. This might be top6 guy for 4th line/sideline money.
