Ragnarsson. I don't think it's broadly appreciated how impressive his performance in the Allsvenskan was.
First of all, the Allsvenskan is a legit pro league. Rob Vollman has found that the Allsvenskan is comparable to the AHL in terms of how tough it is to score in (
Re-approaching the methodology of NHLe).
Secondly, Ragnarsson's 13 points is the most by any U19 defenseman in the Allsvenskan other than OEL and is tied with Mattias Ekholm and Rasmus Andersson. OEL and Ekholm are two of the best defensemen in the NHL today. Andersson is now a top prospect for the Flames who scored almost a ppg in the AHL at 21 last year. (The year after Andersson posted 13 points in the Allsvenskan, he went to the OHL and scored a ppg. As a point of comparison, that's a higher rate than Day just scored at in his overage year).
Ragnarsson played solid defense against pros at 18 and profiles well in that regard too.
I don't think we have any prospects remaining who profile comparably to guys that turned into top caliber NHL players the way that Ragnarsson does. There's a reason he's one of the highest drafted players remaining on this list. Even if there is more risk to Ragnarsson making the NHL than a guy like Meskanen, I'll take the chance on a guy who has a higher likelihood of becoming more than a bottom line player.
Add Pajuniemi. If he was born 4 days later, I think he would have been compared to Kotkaniemi and Kupari in this draft.
