Triangle Stretch concept
There are countless ways to create a triangle stretch, so there is no specific route combination. The idea is to combine a horizontal stretch with a vertical stretch, and provide the QB with a triangle read in a specific area of the field. Running it from a bunched formation gives is a man coverage busting element to the route combination.

The Corner (yellow) and the Curl (orange) create a vertical stretch. The Curl and the Out (red) create a horizontal stretch.
Progression for this specific route combination: Corner - Out - Curl

Blue is vertically stretched as he is wary of the Corner route and has his hips turned upfield. Orange is horizontally stretched as he is wary of the Curl. This opens a window for the Out route to be targeted.



________________________________
The Snag (yellow) and the Curl (red) create the vertical stretch. The Curl and the Flat (orange) create the horizontal stretch.
Progression: Snag - Curl - Flat


Blue is vertically stretched. Orange is horizontally stretched.

Trail concept
- Horizontal stretch at either LB level or safety level
- Effective against: Cover 3, Tampa 2, Cover 2 Zone
- Progression: first In route - 'Trail' route. There are no specific route combinations to use this concept - just the first route, and the route that follows the first route (Trail route).

The In route works to clear the area while the 'Trail' route (red) follows behind with the option to sit down in a quiet area between zones.


In route draws the attention of the middle deep zone defender. If the stretched defender was at the red dot, then the Trail route is not available.

vs Cover 3 (backside man to man)

The pair of routes can be ran at a depth in front of the LB level to stretch an underneath zone defender, or behind the LBs to stretch a deep zone defender. In this play, it is run behind the underneath zone defenders in order to stretch a safety.

Stick concept
- Horizontal stretch on the curl/flat defender; 'Stick' route (yellow Curl) can turn into a Pivot route versus man coverage
- Effective against: Cover 3, Tampa 2, Cover 1, Cover 2
- Progression: Stick - Quick Out (Inside-Out); 3 step timing

The Go route is an 'alert' route (if there is a favorable mismatch), but is mainly a clearing route. The 'Stick' route can be run as an option Curl, Pivot, or quick Out, based on the coverage read of the WR, to run away from the leverage of the defenders in the area.


The stretched defender shades towards the quick Out. The correct throw is to the Stick, which has optioned to Curl.
If the stretched defender is at the red dot, then the correct throw would be to the quick Out route.

vs Cover 3

Couple of variations of the spot concept from 1994 playbook.

Smash concept
- Vertical stretch to sideline zone defender; Corner route can win versus man coverage
- Effective against: Cover 2 Zone, Cover 1 Man, Cover 3
- Progression: Corner - Curl (High to Low); 5 step timing


The sideline defender sinks in depth to cover the Corner route. The correct throw is to the Curl.
If the stretched defender came forward to the red dot to cover the Curl, then the Corner route would be open.



______________________________

Versus Cover 1, the Corner route can win if it has outside leverage on the CB.


With only a cover 1 safety in the middle of the field, and the Curl route preventing the CB from sinking in depth, the Corner route has a lot of room to work.

Thanks, 816. I will change the progression order I had for Spot. I had it as Flat, Curl (snag), Corner. Should have looked you up for the old school WCO concepts.
Crazy how much the Spot, Drive, and Smash concepts (I remember you posting the 49ers' version of Smash) all look the same the first few steps from the X and Z positions.
