Book excerpt: Pittsburgh is synonymous with winning. From the Penguins and Steelers to the Pirates and Panthers, the Steel City knows championships. The Negro League's Crawford and Homestead Grays are too often overlooked in the city's sports history but were as talented as any team that has played there. Names such as Lemieux, Crosby, Roethlisberger, Bradshaw, Clemente and Stargell are legends of American sport and members of Pittsburgh's most cherished franchises. The 1970s Steelers were known as the Steel Curtain. The Penguins have raised the Stanley Cup five times. Author Dave Finoli ranks the fifty greatest teams that won trophies, brought glory and lifted the hearts of Pittsburgh's devoted sports fans.
