What is a tush push in football?

In football, the term "tush push" refers to a defensive lineman technique used to push or drive the offensive lineman backwards by using their hips and lower body strength. This move is often used to gain leverage and control over the offensive lineman, allowing the defensive player to disrupt the play and potentially sack the quarterback or stop a running play. The tush push technique requires strong lower body strength, proper footwork, and good timing to be effective. It is a physical and aggressive move that can help the defensive player gain an advantage on the line of scrimmage.
