response: Your welcome. For the defense, a linebacker is considered the most important, since they add extra protection and give hard hits when it's needed.
history: What exactly is a linebacker? Thats an american football position right Yes, a linebacker is a playing position. American and Canadian football use this term. what exactly is thir job on the team and in game? Well, a linebacker is part of the defensive. They will line up about 3 to 5 yards behind the line of scrimmage, which is behind the defensive linemen. That's how they 'back up the line'. ahh ok, that makes a lot of sense, anything else you can tell me? Well a linebacker's main goal is to either provide protection during a run, or pass protection during a defensive play. oh wow well i dont know much about football so thanks for the info
knowledge: Linebackers are often regarded as the most important position in defense, due to their versatility in providing hard hits on running plays or an additional layer of pass protection, when required.
