D.C. United had such a thin roster of players going into Saturday night's game with the Houston Dynamo, that the field player with the longest Black-and-Red tenure among the substitutes was Luke Mishu. They dressed three goalkeepers, two players who started Saturday played 120 minutes in Wednesday's midweek loss to the Fort Lauderdale Strikers (a third was subbed on at one point), and Andrea Mancini even appeared on the bench, in a regular season MLS game. While Saturday's scoreless draw did give them two straight unbeaten road games, the larger pictures of 304 scoreless minutes and one goal in 527 minutes should be of at least moderate concern.
