This is the problem with Americans. You've got used to watching games only you play and can't conceive of the idea that with a game that virtually the whole world plays, some countries don't play the game as we'd like. The Latin Americans are renowned for exactly the thing you're talking about Budha. British football fans hate it as much, if not more (seeing as they care about being beaten thanks to this sort of gamesmanship) than you.
Oh, and there is no more boring sport to watch if you don't really understand what's going on
than American football. The key bit is the bit in bold, and the same holds true for true football.
