Almost all of the information in this column came from the thoroughly researched and footnoted book, "Interference: How Organized Crime Influences Professional Football," by Dan E. Moldea. However, I first learned of the role of the mob and gambling profession in pro football from Bernie Parrish's book, "They Call It a Game," published in the early 1970s. I interviewed Parrish and learned fascinating things. The major thesis of the book is just what you say: pro football is all about money and it isn't really a game. Parrish devoted an entire chapter to organized crime ties of NFL owners. Best, Don Bauder
