Team USA is in prime position to defend its medal title from the Beijing Olympics. Here are three things to watch as London hosts the 2012 Olympic Games.
Basketball: With NBA stars like LeBron James, Kobe Bryant, and Kevin Durant in the mix, Team USA is favored to win gold. Tough opponents such as Spain and Brazil may have other plans, however.
Swimming: Michael Phelps took home eight gold medals in 2008. But fellow American Ryan Lochte has been tearing up the pool recently and expects to challenge Phelps for swimming supremacy. This will be the rivalry to watch in London.
