USMNT has the ability to call up any player, but they typically defer to European clubs (and player wishes) for long-distance travel for smaller friendlies. Premiership finishes the season about two weeks before the anticipated US friendly date, freeing Dempsey, Howard, and co. providing rest periods are waived. Bundesliga will be finished. Holden should be back from injury. In all, that gives us a decent shot at seeing the A squad if we land the match here in JAX (assuming Kinsmann doesn't save them for the Brazil friendly a few days later.)
I so want this match to happen here.
