To teach a youth football player how to rush the quarterback I would first make sure the pass rushers know the types of rushes that are available for them to use. We would go over the rip, the swat and swim and the bull rush. I like to use a fourth style also I learned while watching a Reggie White interview a long time ago. A player sets the lineman up by favoring the rush to the outside, the when he thinks the lineman is cheating to the outside he employs this other move. At the snap the defender goes up field like he is going to rush the outside, then plants his inside foot while simultaneously getting his inside hand in the armpit of the line man. He then shoves the lineman while he is off balance to his outside, which creates a clear path to the quarterback. One would have to have considerable upper body strength to accomplish this move.
Every player will have a favorite style of how to rush the quarterback, but the objective of this first stage is to get the competent at a couple of other styles. During this first stage, we would also go over the hand and footwork required to use these moves. During the second stage of the staircase I would have the defensive lineman go against the offensive linemen and you can use another player to simulate the quarterback if he is not available, I am sure that he is probably doing more important things. This stage would be at half speed in full pads so the players can get a feel for the new move they have learned. For the third step I would put first team offensive line against the defenders, no matter what string they are. During this process, I would keep tract of which players were using proper hand and foot techniques, and after the drill refresh the memories of the ones who failed to use proper technique. The fourth step would be to use a game to exhaust the player, which would create muscle memory for the moves learned. The game could pit one defensive lineman against a constantly rotating offensive lineman, this way the offensive lineman will be fresh, whereas the defender will be tired.
A coach could use some way to keep track of points to make it a competition on how to rush the quarterback. Creating muscle memory is the best way to have the human body do what you want it to do when a person is so tired that their brain shuts down, it is all about repetition. Unless you see that the players do not understand in practice, the only real proof of whether the system is really working or not will happen on game night. The techniques I would use to teach the pass rush would start with proper stance then jump to proper hand and foot movement and finish with the follow through and properly tackling the quarterback.
The first key point in learning how to rush the quarterback is to recognizing the pass protection. It is stated in the text that this step does not have to be used all of the time. If it is 3rd and 19, the hope is that the defenders can be reckless in their pursuit of the quarterback because the quarterback is probably going to pass, and if they did run the ball there would be a slim chance that they would succeed in getting the first down.
Another key point in how to rush the quarterback is staying in your lane, this one is important because you do not want to disrupt the other pass rushers on your team from completing their task by getting in their way. The last two key points are to use the move taught and to use other moves. The last is especially important; you do not want to be the defender getting pancaked because you do the same rushing move every time. Then during the film study on Monday it will hurt all over again as your teammates laugh. The video really made sense to me because it was a concept that I was already familiar with.
