A streak unlikely to be broken
On 8/16/97, DC United lost 2-0 away to Columbus.
On 6/16/99, DC United lost 3-0 away to Dallas.
They did not score in either of those games. In between, they would score in every regular season game, a total of 52 straight, including the entire 1998 campaign. To give you an idea of how hard this would be to beat, the top streak right now is 7, joinly held by CLB, DC, and COL. The fact is, DC United was just so dominant back then compared to the rest of the league, and it would take some sort of "Superclub" to equal that run...I wonder who that could be? ;)
