We all know about the Sports Illustrated cover curse. And we know the story of the Madden NFL cover curse. But is the worst curse of all just being part of the Washington sports scene? That’s what ESPN claims, saying, “A star-destroying black hole of unimaginable proportions, the Washington curse goes beyond sports, touching everything from reality TV (worst seasons ever for “The Real World,” “Top Chef” and “The Real Housewives”) to politics (the reputation of any popular pol who stays in town long enough).” Ouch. But does the DC area really have a sports curse?
