The full-back position has typically been one of sturdy competence for the United States men's national team. At right-back, you've been witness to the Steve Cherundolos and Timmy Chandlers of the world; the pickings have been a bit slimmer at times on the left, but players like DaMarcus Beasley and Fabian Johnson have still brought professionalism and occasionally exciting play to the position. There's sturdy professional upside, and there's Jordi Alba- or Dani Alves-level upside: In Sergino Dest, the USMNT now has a starting Barcelona full-back in its player pool.
