It's crazy that United States swimming superstar Natalie Coughlin will be swimming one event at the 2012 London Olympic Games.
It's been a crazy couple of years, with Michael Phelps and Ryan Lochte broiled in an intense rivalry that has captured the world's attention, and the emergence of a new wave of stars led by teenager Missy Franklin.
The one event Coughlin is swimming, though, will be extremely important. She has to make a difference for the U.S to win a gold medal.
There's little debate about who wins in the medley relay races. There is just no other country that has the quality and depth in all four strokes.
The rest of the world can certainly compete in individual events, but not many can put together a medley relay team that will challenge the United States.
The freestyle relays are another story. There are plenty of great swimmers around the globe to give the U.S. a run for the gold.
