Team USA hauled in medals more prodigiously than any other country in the world in the 2012 London Games, and some of their athletes will be back for more Olympics domination in Rio to help them defend this title and further their own legacy.
Four years isn't going to be enough time for other athletes to catch up to the following three American gold-medal winners.
Ryan Lochte, Swimming
Ryan Lochte already has six Olympic medals, including two golds, to show from two Olympic Games appearances. He has accomplished just about everything there is for a swimmer to accomplish and he is not done yet.
Lochte is 28, and he is already on record as saying he wants to not just return for Rio, but also add even more events.
At 32, it is unlikely that Lochte will be able to put up as extraordinary of times as he is now, but he won't have to to walk away without some hardware. It wouldn't be a shock to see Lochte leave Rio with double digits in career Olympic medals.
Jordan Burroughs, Wrestling
Jordan Burroughs is unstoppable right now, and he is only 24. He won the 74 kg gold in freestyle in London, and everything else he has been in since 2009.
This gold medalist has not last a match in that span, which includes him winning the Hodges Award for the best collegiate wrestler and the World Championships.
Burroughs is as much a lock to win a gold in Rio as is anyone that is planning on competing, and as Fox Sports points out, he will attempt to defend his Olympic triumph.
Allyson Felix, Track and Field
In her third attempt, Allyson Felix finally got the gold in the 200-meter dash that has eluded her. She also grabbed gold in the 4x100 and the 4x400.
Despite being an Olympic athlete for the past eight years, Felix is just 26, and, as the Associated Press tells us, she is planning on competing in Rio.
It is difficult to imagine Felix not being in the hunt for gold in the 200, and possibly even the 400 if she chooses to run that event instead of the 100 like she did this year.
And of course, she is almost assured medals in any relays she would run in.
