Center is one of the most important positions at the Olympics because of the playmaking and defensive responsibilities included in the role.
Other gold medal favorites such as Canada, Russia and Sweden are deep at center, so much so that some players may be forced to play out of position on the wing.
Team USA would love to have that problem, but depth down the middle is currently the team's most glaring weakness heading into Sochi.
Ryan Kesler is the team's likely No. 1 center given his impressive two-way game and success at the Vancouver Olympics, but his inability to stay healthy consistently with the Canucks is a real concern.
Outside of Kesler, Joe Pavelski and Derek Stepan, the United States doesn't have any other top-tier NHL centers with elite offensive skill to bring to Sochi.
Alex Galchenyuk has a good chance to make the final roster as a skilled center also capable of playing on the wing, but he has just one year of NHL experience.
The other centers invited to the Olympic camp include Trevor Lewis (not skilled enough for the Olympics), Nick Bjugstad (only 11 games of NHL experience), Craig Smith (48 career NHL points), David Backes (good defensively, but his offensive skills aren't ideal for a larger ice surface) and Paul Stastny (key part of 2010 squad, but his skills have regressed in the last three years).
The ideal situation for Team USA is someone such as Stastny, Bjugstad or Galchenyuk having a tremendous first half of the 2013-14 season that proves they belong on the final roster.
If the Americans don't get a goaltending performance similar to Miller's heroics in 2010, the offense may have to carry the team. At the moment, there isn't enough talent or depth down the middle to help the United States beat quality opponents in high-scoring games.
