I think a lot of "foreigners" aren't getting why us finns thinks the goal was so special. It wasn't about the "move", we've seen Rob Hisey&others do the same one in the SM-Liiga.
The reason we are getting so hyped up is that finnish players tend to be really conservative, shy away from taking chances, and always seem to crumble under pressure. It doesn't matter that the average Joe in NA doesn't care about the WHC, because for Granlund, as a finn, there will never be as much pressure put on him than playing for Finland in a WHC(or Olympics). So for a 19-year old kid who the whole nation is expecting to be saviour of finnish hockey, playing under bigger pressure he'll ever face in the NHL, to try a move like that in a scoreless game in the semi-finlans with the whole nation watching at home is very special because we aren't used to seeing that from finns.
I'm not a big fan of the "move" itself, but I am absolutely loving the fact that we may have a superstar in the making who doesn't hide under pressure, and can actually step up when needed.
