In American college football, defenses are often tasked with stopping offenses from scoring points. There are many different types of defenses that teams can run, but one of the most popular and effective is the 4-3 defense. The 4-3 defense is a base defense that uses four down linemen, three linebackers, and four defensive backs. The goal of the 4-3 defense is to create pressure on the quarterback and force him to make mistakes.
The 4-3 defense is a versatile defense that can be used to stop both the run and the pass. Against the run, the 4-3 defense uses its down linemen to create a wall in front of the running back. The linebackers then fill in the gaps and make tackles. Against the pass, the 4-3 defense uses its defensive backs to cover the receivers. The linebackers and down linemen can also drop back into coverage to help out the defensive backs.
