4-3 defense

The 4-3 defense is a football defensive formation with four defensive linemen and three linebackers. The linemen primarily focus on stopping the run and rushing the quarterback, while the linebackers provide versatile coverage—supporting against the run, covering receivers, and blitzing the quarterback when needed. This setup offers a balanced approach, allowing flexibility to defend against both passing and running plays. It’s a common defensive structure that adjusts well to various offensive strategies, aiming to control the line of scrimmage and create pressure on the opposing quarterback.
