As the latest football season unfolds, a timely book by Daniel J. Flynn takes on the do-gooders who would relegate the sport to the ash heap of history. “The War on Football: Saving America’s Game,” explores the history of the sport and debunks many of the myths surrounding its iconic characters. More importantly, Flynn tackles the oft-repeated misinformation about concussions and other health-related issues critics exploit in their attempts to convince Americans the game is far too violent. He also illuminates why the game remains a critical rite of passage in a nation seemingly bent on emasculating young men.
