Zuccarello has been
huge for Norwegian hockey in a lot of different ways. I think it was really important for a lot of young Norwegian hockey players to see Zucca playing in the NHL
and succeeding there. When he was at his peak with the Rangers, the Norwegian press always had updates on how he played, and there was a ton of people with Rangers gear that you'd see quite often. NYC is also a pretty popular destination in the US for Norwegians to travel to, so because he played there I think that also boosted his profile here as well as 0the NHL's and hockey in general.
Plus, he like the most likeable guy ever. He just won an award at the Norwegian Sports Awards for Role Model of the Year for his efforts to make it easier for kids to play hockey, so he's doing a lot of grass roots stuff as well. And he really put Norway on his back to qualify for the 2018 Olympics, and that exposure helped. Great ambassador for the sport.
All that makes it easier for kids to get engaged and increases the talent pool, which hopefully increase the output level of young players.
Oslo just got a brand new ice hockey stadium as well. The old one was really old and pretty dismal, but an up-to-date facility should also help increase turnout to the games in Norway's biggest population center and hopefully interest in the sport.
Like NorwayIce said, there are a lot of obstacles for Norway, but I think the future looks pretty bright at the moment. We just have to hope Pettersen eventually makes the Flames and becomes as good as his Swedish namesake
