That's ok. Here in Europe we have no clue whatsoever about NFL, only when Jay Leno talks about Chicago Bears in a... nice way..
Interesting, because no one in the US really knows much about the Bears either (not a really noteworthy team these days). Luckily for those of us there in the States (do people elsewhere call them that, because American's don't, really) many teams elsewhere are country teams, so we all know who Portugal is.
Worst of all, however, is the fact that the US has a major league soccer/football league, but no one knows the team names, literally. And then we poach someone like Beckham and put him in the unknown league (although to give it some publicicty), it's no quite fair.
But hey, the NFL is trying to play more games in Europe to grow a following there (sold out a stadium in England last year).
One quick trivia question to continue the distraction for the video: What does the word "National" in the phrase :National Hockey League" stand for when the majority of the teams are in the US but the majority of the players are from Canada (who doesn't care for soccer either)?
And one quick piece of trivia, in the US, it is soccer (i.e. football), not American football (NFL version), hockey, basketball, or baseball that has the most kids play it. Strangely though, they don't go on to watch it.
