Defensive line film study — tells and schemes

Film study for defensive linemen is about reading the offensive lineman across from you. Every block has a tell — stance imbalance, eye direction, weight distribution — and the lineman who recognizes the tell wins the rep before contact.

How to use this library

Offensive line tells first — they are the daily-use skill at the position. Run-game schemes from the defensive perspective second, with the optimal disruption move for each scheme. Pass-rush opportunities come third, with film of common protection schemes and the rush moves that beat each.

Each guide identifies the visual triggers and the corresponding defensive technique. Watch your own film with these triggers in mind and your reps will improve measurably — usually by half a second of recognition speed, which is decisive at the line of scrimmage.
