Book excerpt: A tight, dramatic NFL playoff game is exciting on its own, but two of the most dramatic in the same afternoon might result in the most compelling day in football history. This book is the first to capture the excitement and tension of December 23, 1972, when Pittsburgh played Oakland and Dallas met San Francisco in a pair of first-round playoff games that captivated millions. One game saw Dallas rally from three scores down in the fourth quarter, while the other featured the most famous ending in league history--the Immaculate Reception. This book details both high-stakes games as well as the historic season that led each team to the 1972 playoffs. Also covered are the men behind the miracles--some captured the moment to become heroes and legends, while others let success slip through their grasp. Two games, one afternoon, countless memories.
