Going into the 2012 Olympics, the United States is thought to be the front-runner for the gold medal in basketball.
The Americans have already suffered numerous injuries to key players, and are currently thin in the frontcourt. If any teams wish to knock off the United States, they are going to have to attack with size and strong defense. They have been beaten before on the world's biggest stage and it could always happen again.
These are the four teams with the best shot of knocking out the Americans.
