Looking at the roster, it's tough to find a true pattern. Among the 23 players called in, four of them have yet to make an appearance for the United States. Among them are recently declared Americans forward Aron Johannsson and defender John Anthony Brooks. Goalkeeper Cody Cropper and forward Bobby Wood could also earn their first senior-team caps.
Eddie Johnson was the only player who started the past three World Cup qualifiers and was called into the Gold Cup that was called in this time.
