"Football is an art form...because of the rules there are unlimited possibilities." Bill Walsh There are two parts to becoming a master of offensive knowledge on the football field. The first part is that, as a quarterback, you are an extension of the coach on the field and, therefore, must know your offense and all its pieces (players, plays, identity) just as well (if not more) than your coach. Once you understand your offense and how it is trying to attack the opponent, the second component of knowledge is how well you know the defense that is lining up across from you. Can you make quick decisions? Can you anticipate? Are you controlling the game or is the game controlling you? Ultimately, what separates average quarterbacks from good quarterbacks and good quarterbacks from GREAT quarterbacks is their preparation and knowledge of the game with which they play on every snap of practice and games.
