It’s a mystery why Jürgen Klinsmann doesn’t always put Geoff Cameron, Omar Gonzalez, and George John on the United States Men’s National Team roster as three of the four center backs. In the list below, World Soccer Source ranks George John fourth in the USMNT center back depth chart (below Gale Agbossoumonde). Both Soccer America and Soccer By Ives have ranked American center backs, but World Soccer Source believes those rankings don’t include many of the center backs with the athleticism and skill to help the United States improve as a national team on the international level.
