What are the different defensive formations?

Darrin Chiaverini (Football Coach and Professional Athlete) gives expert video advice on: What are the different defensive formations?; What is a '3-4' defense?; What is a '4-3' defense? and more...

There is a tonne of them. You got your four -three, you got your three-four, you got your three-three-five, you got your three-three stack, you got your nickel defense or dime defense, you also got your tempa tu, you got your six-two fronts, you got your eight Men down line. There is tonne of different formations that are ran on any on a given Sunday or any given Saturday, so there's a wide variety of defensive formations. You do it to gain an advantage. If an offense knows exactly where defense is doing, if a team stays in a four-three and that is all they run the whole game, an offense can game plan for that. It can come up with the variety ways to beat that defense so you will see a lot of defenses run the four-three, browse the run the three-three stack, and change it up, that means three down line men, and three line backers and five defensives back. So it gives an offense different looks and different preparation that you have to do to that defense.
