I think this is why the US will never truly "get" the beautiful game, though viewing figures are encouraging. The final wasn't the greatest exhibition but then they rarely are given teams actually have to be pretty well drilled to get there. I'd make a case for the Netherlands- Argentina game being a "better" game than the German demolition of Brazil given it wasn't done and dusted inside 30 mins and we got to see Mascherano give a masterclass in defensive play, cagier by far.
The game has no need to change to "convert" the US, the whole world "gets" it outside the US, and with a rising Hispanic population the US will organically shift its tastes anyway.
Isn't there also a fair amount of hypocrisy when it comes to boring if baseball fans regard a no hitter as a pinnacle of the sport? Basketball - high scoring but individual baskets are almost meaningless and the spectacular happens 20 times a game.
I think the main reason people in the US never got the sport in the past was that few of them ever played beyond the age where they were still mindlessly following the ball around in swarms (cloud soccer, as it was referred to in my youth). Quite a few guys in my school played up to the age of 10, but few stayed on to play U12, U14, or beyond. Combine that with TV networks that rarely ever broadcasted matches or even highlights, and you've got an uneducated and uninterested population.
More and more people are now starting to play into their teens, where they're learning more about the game which will make them appreciate more what they're watching on TV. That plus the larger number of matches from around the world, especially the Premier League and Champions League, will lead to more viewers.
I think one of the quickest ways they could increase viewership even more would be to broadcast more highlight shows. Even if they had to just buy the rights from shows produced in Britain or elsewhere, weekly round-ups for the Premier League, Serie A, Bundesliga, La Liga, Champions League, and Europa League would give new viewers a chance to watch the game in shorter, more exciting pieces with replays and analysis expanding their knowledge and appreciation of the game.
