Michael Phelps: Only three more medals are needed until the 14-time gold medalist becomes the most decorated Olympian of all time.  With 7 events scheduled for London, and Phelps still at the peak of his career, he will be a fixture at the top of the podium for all of the events he enters.

Kerri Walsh, Misty-May Treanor: Competing in their third Olympics as teammates, the two-time defending Olympic gold medalists will aim to win a third consecutive gold.  This won’t be an easy task, as they will be challenged by Juliana Silva and Larissa Franca of Brazil.  With experience on their side, the dynamic duo hopes to pull out another gold medal.

Missy Franklin:  Already a FINA Swimmer of the Year and world-record holder, the 17-year old phenom heads to London with the US expecting big results from her.  So far, she has handled the pressure and delivered in every big moment.  While the Olympics will be the biggest stage she has ever competed on, with 7 events scheduled, she should bring back plenty of medals for American swimming.

Ashton Eaton: After breaking the 11-year old world record in the decathlon at the U.S. Olympic Trials in June, Eaton heads to the Olympics as the clear favorite in one of the toughest Olympic events.  With the whole world watching and also expecting nothing but gold from him, his performance has the potential to again be remarkable.

Ryan Lochte: Lately, you can’t mention Michael Phelps without also mentioning Lochte, the current world record holder in the 200 IM and one of the few swimmers who has defeated Phelps in major competitions.  Their duels in the 200 IM and 400 IM at the US Olympic Trials makes their races in London highly anticipated.  With 5 events scheduled, the 27-year-old out of the Gator Swim Club should challenge Phelps and also bring back many medals for Team USA.

Gabby Douglas: Leaving her hometown 2 years ago to train with a different coach seems to have paid off huge dividends for the 16-year old first-time Olympian out of Virginia.  Exploding on the national scene, she will be a crucial part of the US Gymnastic team in their quest for a team gold.

Maya Moore: One of the most successful collegiate women’s basketball players ever, the No. 1 overall pick in the 2011 WNBA Draft looks to assert her dominance on the international stage in her Olympic debut.  With the 23-year old leading the US team, they head to London as the gold medal favorites.

Tyson Gay: Although Usain Bolt is a heavy favorite to repeat in London, the USA’s best chance at knocking off the Jamaican sprinting dynasty lies in Tyson Gay.  Fully recovered from a hip surgery, the sprinter is peaking at the right time, winning his Olympic tune-up in Paris and heading to the Olympics with confidence that should help him emerge as a gold medal contender.

Lebron James: Coming off of his 1st NBA Championship in June, “King” James heads to the Olympics full of confidence and ready to lead the US in their quest to repeat as Olympic champions.  With a loaded roster of NBA All-Stars—many with Olympic experience— anything less than a gold medal will be a disappointment for USA Basketball.

Alex Meyer: The lone American male in the 10K open water event, and the first American athlete to qualify for the Olympics, Meyer heads to London having endured several setbacks over the past few years: a broken back in 2009, the pain of losing a friend and USA teammate in Fran Crippen in 2010, and a broken collarbone in 2012.  His mental and physical fortitude will be put to the test in London in the highly demanding 10K race.  But if anyone can break through barriers and succeed, it’s going to be Meyer, who is one of the toughest racers on the planet.
