The offensive tackle (OT, T) is a position of 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. The term "tackle" is a vestige of an earlier era of football, in which the same players played both offense and defense. In the current version of the A-11 offense, offensive tackles are known as "anchors," and have a significantly different role.
