The Double Tex line stunt is a great way to use all five linemen while keeping gap integrity in the middle of the formation. The point of using a Tex stunt is to bait the quarterback into stepping up the field, or the offense into running a QB draw. Many DCs are afraid to blitz Empty because of the threat of the QB draw. Using Tex stunts allows the DC to gain all back seven defenders in coverage while putting pressure on the offensive line.
The defensive ends screaming up the middle eliminates the threat of a QB draw. In the diagram below, the DEs presses upfield to get the tackles to kick out to them. The Tackle and Nose loop to the outside shoulder of the offensive tackles and secure contain. Once the offensive tackles kick back, the DEs loop in and aim for the inside hip of the guards. Against “big-on-big” (BOB) protection, the Center should step to the Nose. This opens the weakside “A” gap for the incoming boundary DE and looks like an enticing window for the QB to step up into. Even if there is a draw on by the QB, he will be stepping into two incoming DEs.
The coverage piece behind it can be whatever the DC is most comfortable with against Empty. In the case below, a “loose” Special scheme is the chosen coverage. The Mike and the Will are allowed the luxury of hanging outside because the DEs are responsible for the interior gaps. If the Nose or Tackle cannot get to the outside, the Mike and Will are able to attack the QB once he leaves the pocket or the QB bounces outside on a draw. The great quality of the Double Tex stunt is it gives the DC the best of both worlds, it protects the interior line from a QB draw and allows all the back seven players to drop into coverage.
One of the hardest sets in football to defend is the cluster or stack set. Spread offenses utilize this set to get the defense’s outside linebackers in run/pass conflicts. Unlike a traditional 2×2 set, the defense has to adjust to the width of the receivers. Stacking them creates width, and width creates the conflict. Spread teams rely on the open “B” gap to build their RPO’s and offensive gameplan. By stacking the receivers out wide, the defense is forced to adjust. In a two-high system, the player in conflict (usually the Will LB) has to choose, cover down to his receiver or hold tight to the box. If he stays close to the box, the offense is going to throw the quick screen and create a 1-on-1 open field tackling matchup with the safety or corner. In most cases, the defense wants to avoid this as much as possible. On the other end of the spectrum, if the defender widens to the cluster set, the offense has a 4-1 box and a clear running opportunity. Versus a two-high system, there is a great chance for the offense to part the field like the Red Sea for a big gain. Ask any offensive coach, a 4-1 box is a magical thing.
In the image below, Penn St. runs and Under front and “hips” it’s Sam LB to the strength. In most RPO style offenses, this is a clear pass read. The Sam has to honor the run read and step to his gap. Even with zone away and a gap exchange with the crashing DE (in this set the DE has dive), the Sam has to take a step towards the box. The QB is taught to read the Sam’s path and throw the screen. Penn. St. is most likely in a “Cloud” coverage (Two Read) and the safety is bailing on the snap. Easy pickings for any decent offensive coordinator. It’s a conflict of philosophy; the offense wants 1-on-1 matchups and the defense wants a plus-one. In order to create a six-man box and protect against the run, the defense has to spin to single-high, but to keep a plus-one in pass distribution it has to stay in two-high, something has to give. MatchQuarters explores the options.
