This is the second in a five-part series on The History of the San Antonio Spurs (© Whitman Publishing, LLC), which was recently released and is written by Sheridanhoops.com columnist Jan Hubbard (twitter: @whyhub). In this excerpt, the roots of the Spurs franchise are traced back to the first six colorful, but largely futile years the franchise spent as the Dallas Chaparrals. (You can order the book here.) The Chaps managed to last six seasons in North Texas but never generated excitement.
