For D.C. United, the past, present and future will collide over 48 hours.
The first and last are worthy of celebration, the other of consternation.
The past: The last MLS original team to remain at the same home venue will mark the 20th anniversary of its RFK Stadium debut.
The present: With a 1-3-3 league record and somber attack, United is itching for goals and three points against the New England Revolution on Saturday.
The future: On Monday morning, club officials and staff will join Mayor Muriel E. Bowser at Buzzard Point in Southwest Washington for a demolition ceremony at the site of a proposed 20,000-seat stadium, slated to open in 2018.
