When you hear the announcers say "So and so is competing in her first Olympics, she's a Freshman at the University of Georgia" then she's an amateur.
When you see the swimmer from Hungary with the steroid freak husband who blows a gasket everytime she wins a medal, that's a professional athlete.
Nice to see our amateurs beating other countries professionals.
As far as the US basketball team; college kids were playing other teams professionals for years, so we sent the dream team and that was that.
That said the US mens team has had to very close calls so far and the US womens soccer team lost to Sweden?
How is that even possible; oh yeah, the Swedes hired the former US coach and they played a defensive style game, keeping it close and winning on a shoot out.
And sorry, as much as I like Soccer, that is the lamest way to settle a match, it comes down to which teams shooters will choke the most, like kicking the ball right at the goalie or worse yet, missing a net the size of a tractor trailer..............................
