A Strongside Linebacker (often abbreviated as SLB) is a defensive player in American football who primarily lines up on the side of the field where the tight end is located. This position is crucial for stopping the run and covering short passes. The SLB must be versatile, combining strength to tackle and agility to cover receivers or tight ends. In a typical defensive formation, the SLB works alongside other linebackers, such as the Middle Linebacker and Weakside Linebacker. They often face challenges from offensive plays designed to exploit their position, making their role vital in maintaining defensive integrity.
