This book is about the NFl's record breakers. In this book you can find all the people who will go down in history, and what they did to ge there. It tells about when teams went undefeated and went to win the super bowl, and when teams couldn't ever win. It also tells you what the rushing, or passing yards record is, and who holds it. And it has defensive records too. I think if your a sports fan, this would be a good book for you. ( )
