An Outside Linebacker is a position in American football, typically part of the defensive unit. They line up outside the defensive formation, often near the defensive ends. Their primary responsibilities include stopping the run, covering receivers, and rushing the quarterback. They need to be versatile athletes, combining speed, strength, and agility to perform their duties effectively. Outside linebackers play a crucial role in both pass defense and run defense. They must read the offense's plays quickly and react accordingly. This position is vital for a team's overall defensive strategy, as they help contain outside runs and pressure the opposing team's quarterback, contributing to the success of the defense.
