Five defenders are locks to make the trip to Brazil, but the other three of the projected eight defensive spots are still up for grabs with plenty of names in the mix.
Right-Back: Geoff Cameron
If Cameron is not in the starting 11 for the first match against Ghana, something is truly wrong with Klinsmann.
He is in terrific form at the right-back position for Stoke City in England, and he delivered a strong performance against Ukraine from the same spot on the pitch.
Klinsmann could move Cameron to center-back or defensive midfield because of his versatility.
Center-Backs: Omar Gonzalez and Matt Besler
Gonzalez and Besler are the best center-back pairing that the Americans can put together, and they have grown into a respectable duo.
The two MLS-based products have solidified a position that Carlos Bocanegra occupied for years and have made it their own.
Left-Back: DaMarcus Beasley
For at least the first game in Brazil, Beasley will be the starting left-back.
There is reason to be concerned about his age and how he will hold up against the talented wingers in Group G, though.
Regardless of how much playing time he receives in Brazil, Beasley will be important to the U.S. squad because of his vast experience at both the club and international levels.
The Reserves: Clarence Goodson, Brad Evans, Michael Parkhurst, Michael Orozco
Goodson and Orozco should be called into the squad to be the reserve center-backs.
Both players have done well when called upon, with Orozco's showing at Azteca against Mexico in 2012 being the most notable one.
Evans has done an admirable job at right-back over the last year, but he is a natural midfielder and will not be playing in the back four for the Seattle Sounders in MLS this season. Despite all of that, he is a lock to go to Brazil because of what he did to help the Yanks get there.
Parkhurst moved back to MLS during the offseason to make his way onto the squad, and he should earn the eighth and final defensive spot.
The right-back does have to play well for Columbus, but right now he is the best option to take to Brazil.
