Tite Leo

Tite Leo is a run-stopping, pressure-disguising front inside the 4-3 formation that uses the Base 5-2 personnel package. It uses a Tite alignment: a nose tackle (NT) head up or shaded on the center, two interior ends pinched into 4i techniques on the inside shoulders of the tackles, and two rush ends (RLE and RRE) set wide on the edges. Standard 4-3 Over and Under sets rely on a traditional four-man line with three linebackers. Tite Leo puts a fifth body near the line and plays two linebackers behind it. The result is that the A and B gaps are clogged before the snap, the guards cannot climb cleanly to the second level, and the linebackers are free to scrape and fill.

The 5-2 structure changes what offenses can do against you. Inside zone, duo, and power concepts run straight into the nose and the 4i ends, which forces the ball to bounce outside toward the rush ends and the force defenders. Because each edge has a true rush end, offenses lose the easy chip-and-release option on tight ends. Opponents usually have to keep a back or tight end in protection, which caps their route count and makes isolating a receiver harder.

The play list is built around disguise. The Saw Blitz family (0, 1, 2, and 3) sends the same pressure look but changes the coverage behind it. Field Blitz 3 and Hot Blitz 3 bring pressure from different angles while keeping three-deep safety help. SS 2 Trap, Cover 4 Drop, Cover 6, Tampa 2, Cover 3 Match, and Cover 3 Sky give you a full set of zone shells from an identical pre-snap picture. The quarterback cannot tell whether he is facing Cover 0 heat or a soft quarters shell until after the snap.
