March is a big month for the U.S. men's national team player pool.
The competitive stakes are clear for the Under-23 national team, with the goal of qualifying for the Olympics for the first time since 2008 apparent for some time. On the senior level, there's little opportunity left to tune up before this summer's Nations League semifinals and the fall's start to 2022 World Cup qualifying, and matches vs. Wales and the Netherlands in Europe are fine tests, on a friendly level, anyhow.
That gives the U.S. men's braintrust of sporting director Earnie Stewart, general manager Brian McBride, senior coach Gregg Berhalter and U-23 coach Jason Kreis some serious sorting out to do.
