Eleven Olympic medals and she looks to be through.
For Natalie Coughlin, the weekend was the end of one of the better U.S. Olympic female swimmers in history.
Based on a career that saw her become the first woman ever to swim the 100-meter backstroke (long course) in under a minute.
At the 2008 Summer Olympics, she became the first U.S. female athlete in modern Olympic history to win six medals in one Olympiad, and the first woman ever to win a 100-meter backstroke gold in two consecutive Olympics 10 days before she turned 20 years old.
It has been that kind of success that makes her one of the best in the world. Now starts the debate of how good she is and where she ranks all-time in United States swimming history.
Here is where she is ranked in my assessment of the best America has seen in the pool. And based on this list, the rankings are very tough to determine.
