Which member(s) of the USMNT’s Gold Cup squad should be capped by the ‘A’ side?

It's been a pretty impressive CONCACAF Gold Cup tournament for the U.S. Men's National Team (though it's not over yet. Sunday's Giants Stadium finale against Mexico could turn it into a giant disappointment). There have been several individual standouts among Bob Bradley's mainly young squad. Can any of them improve the team that will travel to Mexico City's Estadio Azteca Aug.
