Sample's autobiography, released not very long after he retired from pro football, is a most direct accounting of his time in the game and life up to that point. Like pitcher Jim Bouton (who penned the controversial Ball Four around the same time) he was viewed as a fringe outsider in his profession, but in reality was among its most meticulous and sure-fire practitioners. He took advantage of every tool at his disposal, including a rating system for opposing players - especially the ones he believed he could easily intimidate. It's a little too quick of a read, though.
