I was watching a football game recently that struck a chord with me. I noticed that as the quarterback took the snap from the center, the opposing team changed its assignment and morphed into a mass of confusion from my vantage point as small defensive backs rushed the quarterback while larger defensive linemen took off to cover a receiver. For those that follow football, this is completely counter-intuitive because football is traditionally made up of specialized positions in which each player has a role to play and tend to be matched up according to size, speed, and other attributes. However, as offensive players have become more versatile, the defensive players have had to adapt so that an unfair advantage does not sit solely with the offense, when a play is called. The defenses have developed schemes and tricks to fool the offense into believing that they are going one way, when in fact they are doing something totally different.
