One of the main reasons the leg lift is used as a cadence is for loud stadiums. Teams in college especially have stadiums packed with over , people in them. Coaches wear headsets to block out the noise; players need an alternative to the verbal cadence to block out the noise. Their alternative is to use the leg lift or the hand wave to tell the center to snap the football.
Communication from quarterback to the center is one of the, if not the most important, communication to happen on the field. Negative and game-changing plays happen when the ball is snapped either too early or at the wrong time. Quarterbacks can be seen lifting their legs in the air to signal the center to snap the football. This leg lift can also be used to fool the defense and fake the snap.
Teams have also used the leg to move a receiver across the formation or any movement. Teams who run shotgun spread offenses are more likely to use the leg lift in their offense than teams under center.
The last thing you want is to be in an important game, and the center cannot hear the quarterback. This can be installed by having your center look through his leg, and the second he sees movement, snaps the football.
Another way is for the center to look through his leg when he sees movement, reposition his body to get set, then snap the ball. We have talked about the hip power of the back leg and ensuing full weight transfer over the front leg, which all lead to the most important correlation in this study, step length.
Again, knee flexion is key here because too large of a step will cause the front knee to straighten and lock out during the throw. Such over striding and knee straightening puts the quarterback at significant risk during contact from the defense. See the picture below of Tom Brady incurring the oncoming pass rush with an extended knee. Below is a great drill that encourages hip drive, but also landing on a flexed leg. WE have also added a medicine ball rotation to encourage upper back rotation found in all overhead sports, but specifically helps quarterbacks stay upright rather than bending at the waist.
Since the mechanics are so intertwined, it is no accident that the most successful passing quarterbacks are the most likely to stay healthy.
