Everage Richardson is the world's top-scoring basketball player. You've probably never heard of him, because like thousands of American players, he's taken his game overseas. Three years ago, he moved from Brooklyn, N.Y., to Elbingrode, a town of 6,000 in the Harz Mountains. Das Schwarze Perle — "The Black Pearl" — as he is known here, averaged an astounding 42 points a game. Connor Donevan reports.
