Soccer has been here as long as in the rest of the world.
Read up on 1950, when we beat England in the World Cup.
Read up on 2006, 2002, 1998, 1994, 1990...when everyone and their brothers beat the US. Outside of the World Cup I watch exactly zero minutes every four years of grass fairies feigning "injuries". Got to admit though, it is damn hilarious when an "injured" grass fairy is carted off the pitch only to jump off the stretcher 10 seconds later to rejoin the "action".
