Tackle is a playing position in American and Canadian football. Historically, in the one-platoon system a tackle played on both offense and defense. In the modern system of specialized units, offensive tackle and defensive tackle are separate positions.
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.
A tackle is the strong position on the offensive line. They power their blocks with quick steps and maneuverability. The tackles are mostly in charge of the outside protection. If the tight end goes out for a pass, the tackle must cover everyone that his guard does not, plus whoever the tight end is not covering. Usually they defend against defensive ends. In the NFL, offensive tackles often measure over 6 ft 4 in (193 cm) and 300 pounds (140 kg).
