When the offensive line can effectively block down and take any blitzing linebackers and sweep them up into the wall they turn a defensive blitz into an advantage for the offense.
One of the most frustrating things that can occur when you are running an offense is to go against a blitz heavy team. This is true at all levels but is especially true at the youth league level. At the youth level it is more difficult to throw and complete passes that can exploit the weaknesses of the blitz. To deal with this it’s best to have multiple answers to the blitz but one of the most effective answers is to run the Power play.
In the Power play the offensive line is blocking down on the fronts side of the line. They are told that they are first responsible for their gap. This means that if any linebacker blitzes through their gap they will block them down to form a wall.
