RNS Curl Flat is a quick-hitting Shotgun Spread pass concept out of 10 personnel that isolates a curl and flat combo to the left while a corner route works up the right sideline and a shallow drag crosses underneath from the right slot. The left outside receiver sits down on a curl at intermediate depth while the inside receiver releases to the flat, creating a natural high low stretch on that side. The right slot receiver runs an angled crosser toward the middle of the field, giving the quarterback a checkdown option away from the curl flat combo. Primary progression starts with the curl, works down to the flat, then comes back to the crosser if both are covered.
Read the flat defender first, since a linebacker or nickel corner sitting too far inside opens up an easy pitch and catch to the flat. Watch the corner route on the right side, because if the safety rotates late to help over the top, the quarterback should already be progressing to the curl or flat. Key the middle linebacker depth, since a shallow drop from him signals he is sitting on the crosser and taking that option away. Against man coverage, look for natural picks created by the curl and flat routes crossing paths near the line to gain, which can spring the underneath receiver open. If the defense shows a blitz look with the slot defender crashing, expect the crosser to be uncovered as the hot read against pressure.
Attack this play against Cover 2 and Cover 3 shells since the curl sits right in the intermediate hole those coverages struggle to close.
Pre snap, identify if the corner over the curl side receiver is playing off man or bailing into a zone drop, since that dictates whether the curl or flat opens first.
Use the flat route as your answer against Cover 2 corners who jam and then sink, since the flat defender often widens late and leaves a throwing lane.
Hot route the crosser into a deeper dig if you see zone defenders sagging underneath, giving your quarterback a bigger throwing window over the middle.
Pair this play with Curl Flats or RNS Hook in the same set to keep the defense guessing between quick game concepts that look identical pre snap but attack different levels.
