One of the easiest ways to add a player to the box, and keep the outside linebackers in their cover downs can be to use a Tex stunt, or Tackle/End twist. Against heavy zone teams, the Tex stunt can be a great way to add numbers to the box without inserting a LB or spinning a safety. In the diagram below, a double Tex stunt is shown. By twisting the defensive lineman, a defense is able to gain an extra man because the play side tackle is literally blocking air. In a zone scheme, the line works together and blocks their zone. In inside zone, many teams will use “team” blocking and head-up to outside principles. This allows the defense to take advantage of zone principles.
The Tex Stunt
In the diagram above, the defense is running a double Tex stunt with a Two-Read scheme in the secondary. The Nose and the Tackle are pushing vertical through the “B” gaps, and if possible, reach the cut-off, or “C” gap. Both Ends take vertical steps then wrap inside, inserting themselves in the “A” gaps. The OLBs are holding the curl and attacking anything that bounces outside. The Mike is still responsible for the RB and inserts himself in away-side “A,” depending on which way the offense zones. The play side DE is the “free” player. The most likely scenario is the Center climbs to the Mike leaving a vacated play side “A” gap. The DE that is folding should hit the gap cleanly and make the tackle in the backfield.
The most likely scenario versus zone is the Center climbs to the Mike leaving a vacated play side “A” gap. The DE that is folding should hit the gap cleanly and make the tackle in the backfield. The away side DE should react to the zone movement away along with the Tackle. As the 3 tech. steps vertically he should notice the guard leaving him and react by closing off his backside and hold his “B” gap. The folding DE should see play away and work back down the line (cutback-QB-reverse). In theory, the Mike LB should be gapless to the backside and be able to react late to a QB pull. As the Center climbs to take him, the Mike should insert himself on the away side “A” gap shoulder. If for some reason, the Nose can’t get to cut off and the play bounces, the Will should be there to take “C” gap. Playing a Two Read behind the front allows the OLBs to hang in the curl and attack “C” gap when the ball is handed off.
