Yes, and no. Middle linebackers are often the defense's quarterbacks, assigning specific players to specific plays. A middle linebacker needs to be able to handle physicality at the line of scrimmage, and have enough speed to stay with bigger backs downfield. Middle linebackers usually get their name because they're expected to take on the role as a quarterback within the defense. They'll typically cover one side of the field or the other, but can also be asked to drop back into coverage if needed. Middle linebackers are usually very smart players who know exactly what they're doing on every play. Because of this, they tend to enjoy a high level of respect from their peers and coaches. Middle linebackers can come in many different sizes and strengths, but most stand between 6'0" and 6'4" and weigh around 220 pounds. The size of a middle linebacker tends to vary a lot depending on how big a team's scheme is.
