Importance of defensive deception

If you found it perplexing that the Arizona Cardinals and Atlanta Falcons were able to bottle up two of the NFL's best quarterbacks in Week 2, you have good company -- namely, Tom Brady and Peyton Manning.

While the Cardinals disrupted Brady and the Patriots' prolific attack, the Falcons forced Manning into three first-quarter interceptions. How were those defenses able to confuse two future Hall of Famers? Through the art of deception, a practice more essential than ever as defenses confront the best group of NFL quarterbacks in league history.

History is a good place to start since what we saw in Week 2 is nothing new.

Confusing the QB has been a guiding principle of defenses for a long time. I look at what the Falcons did on Monday night -- late defensive movement, lots of two-point stances -- and I remember seeing those same principles in person in 1969. Of course, back then I was a senior at Lackawanna (N.Y.) High School, and the defense was employed by coach Jules Yakapovich and Kenmore West High.

Any year, at any level of football, you will see similar principles. The goal has always been the same: Create chaos and rent space in the QB's head. If you can distract him for even a split second before or after the snap, that's a victory for the defense.
