The pictures were cool, and a lot of the history is fun to look at, but it really is just a coffee table book you flip through for ten minutes and never look at again. Kids into football will enjoy the pictures and it should open up some conversation about how the game used to be. Beyond that, it has little staying power, and since the NFL is behind the book everything is pretty whitewashed.
I didn't see anything about missed calls, terrible football video games, gambling (or fantasy football), steroids, domestic violence, racism, kneeling, obnoxious fans, or concussions.
I once loved football. I played, watched, and coached the game pretty fanatically, but we can't ignore the bad that comes with the game. Now that I'm a father, I don't want my son playing the game, and I hope the NFL folds in the next 20 years.
