U.S. players with most to prove ahead of Mexico match

It is often a nebulous task to define progress within the United States men's national team, especially in non-World Cup years. The significance of the team's results varies based on the quality of opponent, the availability of the players and the overall notoriety of the tournaments the team plays in. However, there is little ambiguity for U.S. team progress in 2015, as manager Jurgen Klinsmann has clearly stated that his goal is for the team to qualify for the 2017 Confederations Cup in Russia.
