I'm just thinking out loud a little...
I know it's not the end-all, be-all, but I just wanted to compare Norlinder to Romanov for a moment. They're both the same age, Romanov being 3 months older.
This isn't as much about Romanov, per se. It's more about Norlinder. Romanov is probably going to be named the top defenseman in the WJC, and if he isn't he'll be in the running. If he does get named top d-man in the tournament, that'll be two years in a row for him essentially being the top defenseman of his participating age group. Yeah, yeah, I know that Dahlin isn't there, that Bowen Byram might be better one day (would be surprised if he wasn't, but I digress), Sandin looks like a future stud, etc. Romanov should, in all likelihood, be in the NHL next year.
Now, for Norlinder... He's averaged 10 minutes of icetime during the tournament as one of the older players on the team. Sweden isn't exactly a defensive juggernaut, despite having 5 first or second round picks on the team. Outside of Sandin, none of them make me go wow, look at him!. I'm not discrediting them, but they're solid. Broberg is overated and skates at a speed that is too fast for his brain to compute, but that's another story.
Romanov stood out against players of his age group for two straight years, has played in the second/third best league in the world at 18 and looks destined to be a long-time NHLer. Norlinder is lagging behind players of his own age group, is doing pretty well in Sweden's second best league and has a lot of question marks about him.
Can we just be a little patient with him and wait a little bit? It's worth repeating, but before seeing him in North America, I want to see him in the Swedish Elite League. The Allsvenskan is nice, but the level of play there isn't great. Hell, I wouldn't mind if he stayed in Sweden for another two years after this season. He's not going to be ready overnight.
