prevalent in the late nineteenth and early twentieth centuries, a tackle played on both offense and
defense. In the modern system of specialized units, offensive tackle and
defensive tackle are separate positions, and the stand-alone term "tackle" refers to the offensive tackle position only. The offensive tackle (OT, T) is a position on the
offensive line, left and right. Like other
offensive linemen, their job is to
block: to physically keep defenders away from the offensive player who has the football and enable him to advance the football and eventually score a

Wonderlic Test, with an average of 26. The Wonderlic is taken before the draft to assess each player's aptitude for learning and problem solving.
The distinction between right and left tackle has become less relevant.
Right tackle
The right tackle (RT) is usually one of the team's best run blockers. Most running plays are towards the strong side (the side with the

) of the offensive line. Consequently, the right tackle will face the defending team's best run stoppers. He must be able to gain traction in his blocks so that the running back can find a hole to run through.
Left tackle
The left tackle (LT) is usually the team's best pass blockers. Of the two tackles, the left tackles will often have better footwork and agility than the right tackle in order to counteract the pass rush of defensive ends. When a quarterback throws a
forward pass, the quarterback's shoulders are aligned roughly perpendicular to the
line of scrimmage, with the non-dominant shoulder closer to downfield. Right-handed quarterbacks, the majority of players in the position, thus turn their backs to defenders coming from the left side, creating a vulnerable "blind side" that the left tackle must protect. (Conversely, teams with left-handed quarterbacks tend to have their better pass blockers at right tackle for the same reason.)
A 2006 book by
Michael Lewis, ''
The Blind Side: Evolution of a Game'', made into a
2009 motion picture, shed light on the workings of the left tackle position. The book and the film's introduction discuss how the annual salary of left tackles in the NFL skyrocketed in the mid-1990s. Premier left tackles are now highly sought after and are often the second highest paid players on a roster after the quarterback; in the
2013 NFL Draft three of the first four picks were left tackles, and usually at least one left tackle is picked in the first five positions.
