The old adage that "it's not how you start, it's how you finish" is quite appropriate as it relates to the U.S. men's national team. Coach Gregg Berhalter has talked often about how his rosters refer to a "slice in time" for the U.S., that not everything is set in stone and that things could change.
Surely, along the way through 11 games and five months of World Cup qualifying, some roles are more of a given than others, but the U.S. player pool on the whole is rather fluid, even if the upper echelons of it have been whittled down.
