The Redskins are like, the worst team ever.
As a fan of the 5 time Super Bowl Champions, the Dallas Cowboys, I have to disagree. The Cowboys and Redskins (apart from the obvious Western imperial expansion - colonial domination metaphor) have been bitter rivals since before the Cowboys were part of the NFL. The 'Skins have won here and there, been a good foil for Dallas and generally go about their business with respect (props to Joe Gibbs).
The mantle of worst NFL team ever is the Cincinnati Bengals. No titles, no really remarkable players or history. Some Americanos will even refer to some girls as Bengals - great body but gash grill. The Bengals have consistently had the worst helmets in the NFL, ever.
I'll give some props when due and I can't abide the Redskins being called the worst team ever.
