This book interested me because I stopped following the NFL more than three years ago; pushed over the edge with the Ray Rice situation and further convicted because of many other issues that convinced me the league led by Roger Goodell was at best highly unethical and at worst an outfit of organized crime.
Mr. Freeman, who is a talented and passionate writer and researcher, lays out his reasons for believing the NFL is in trouble for the long run despite its immense popularity at the time this was written (2015) as well as today. He goes mostly into mainstream league image issues as well as those to do with health of the players. He does well to document their lack of response to the disgusting amount of domestic abuse by their athletes and their refusal, until it received media attention, to protect their players from brain damage.
I do think he missed or ignored a huge factor in their potential demise and that would be PED use. Though the media has hardly given it mention, anybody who knows anything about sports and fitness can tell you it is nearly impossible to play in the NFL without steroids. However bad the problem was in MLB, it is infinitely worse in the NFL and the health repercussions are every bit as frightening as those from CTE. Combine the two and it is downright cruel what we are allowing to happen in the name of entertainment.
Overall a good and informative read, but he didn't nail it down in my opinion. He missed the elephant in the room, like seemingly every other NFL writer.
