The only thing I knew about football was from watching it on TV. I picked up enough information to enjoy the game, but occassionally I got perplexed by commentator remarks and wished I knew what they were talking about. So I bought the "Idiot's Guide to Football", learned a lot more, but still felt unfulfilled. Then I broke down and bought another book, the "Dummies" version, and got exactly what I wanted. This book covers much more detail and doesn't talk down to you. The Idiot's version, while trying to be humorous, succeeds only in insulting your intelligence. If one were to absorb all that is contained in "Football for Dummies", you may not get any calls for head coaching jobs, but you'll certainly better understand the jargon and the meaning behind a lot of the decisions that are made during and before a game. It even covers team motivation, player training and diet, fantasy leagues, the draft, game scheduling, high school and college football information, and a fairly large football- speak section that covers more ground that most other glossaries I've seen. This book contains everything you need know about football to understand and enjoy the game.
