Why the USA women's gymnastics team named itself the 'Final Five'

The American team of Simone Biles, Aly Raisman, Lauren Hernandez, Madison Kocian and Gabby Douglas won gold in the women's team all-around in historic fashion Tuesday in Rio de Janeiro, blowing away silver medalists Russia by 8.2 points to record the largest margin of victory under the current scoring format. Everyone expected Team USA to take gold, but they put on spectacular performances from start to finish. 

The team announced ahead of the final that they would reveal their team nickname once the competition was over - and after the final scores were posted and the gold medal became official, the gymnasts gathered in a circle and yelled "we are the Final Five" to the cameras. 

There's are a few meanings behind the name. Most obviously, the 2016 team is the last one guided by gymnastics legend Martha Karolyi, who is serving as the national team coordinator. The Karolyis have been instrumental in turning United States women's gymnastics into an international powerhouse over the last few decades, but the 73-year-old has said that the 2016 Olympics will be her last.  

The Final Five will also be the last five-woman team to compete in the Olympics, period. A new format for Artistic Gymnastics will be introduced for the next Summer Olympics in Tokyo in 2020, and team size is set to be reduced from five gymnasts to four. You probably remember the Magnificent Seven, who competed in the last Olympics to allow a team size of seven athletes in 1996. The number was set at 6 in Sydney, Athens and Beijing, and then cut to five for London and Rio de Janeiro. In addition to a four-gymnast team in Tokyo, two additional gymnasts will be be able to qualify for individual events or for the all-around competition.
