Breakdown

Under Z Curl is a five man route concept out of Singleback Tight Y Off Flex that stresses the middle of the field with a curl sitting down at the sticks and a deep crosser working behind it. The X receiver runs a deep in breaking route across the field, the Y and slot both push vertical up the seam and numbers, and the flexed TE runs a shallow out of the backfield area to the flat while the RB releases underneath to the opposite flat as a checkdown outlet. This is a zone beater at its core, using the curl and deep crosser combo to sit in soft spots created by zone drops, with the primary read progression starting at the deep crossing route working to the curl sitting at the sticks, then working down to the flat and checkdown routes if the middle is clogged.

Defensive Reads

Pre-snap, identify if the corner over the X receiver is playing off man or bailing into zone, this tells you whether the deep crosser will have room to work Watch the middle linebacker depth at the snap, if he sits shallow to jump the curl route you need to get the ball out quickly before the window closes Cover 3 zone drops can be a problem for this concept since the deep third defenders can sink under the crosser, look to check down to the flat routes instead Man coverage with no safety help over the top is where this play shines, since the curl sitting down and the crosser working across create natural picks and rubs If you see a nano blitz or edge pressure package pre-snap, get rid of the ball on the quick curl or hot route the RB into a quick release to avoid the sack

Usage Tips

Look at the safety alignment before the snap, if you see two high safeties sitting deep this play works well because the crosser and curl will find soft spots underneath the shell

If the defense shows man coverage with a single high safety, prioritize the deep crossing route since it creates natural separation against man defenders trying to trail across the field

Use this on second and medium to third and short situations where the sticks route from the curl gives you a manageable conversion target

Hot route the checkdown RB into a flat route or quick out if you see linebackers dropping deep into zone to take away the shallow crosser

Pair this play with PA Y Middle Screen or Shallow Cross from the same set to keep defenses honest, since both plays attack similar areas but punish different coverage shells
