Book excerpt: The Packers the only fan-owned team in any of North America's major pro sports leagues-- and Green Bay (population 104,057) is the smallest city with a big-time franchise. They're unlikely candidates to be pro football's preeminent team-- yet nobody in the NFL has won more championships. In honor of the team's 100th anniversary, Beech paints compelling pictures of a franchise, a town, and a fan base-- from the days of the French fur traders who settled on the shores of La Baie in the seventeenth century, to the team's pursuit of its fourteenth NFL championship. -- adapted from jacket
