Flat

The Flat tag identifies every play that sends a receiver, back, or tight end into the flat area outside the numbers, whether it's a running back leaking out of the backfield on Curl Flat, a tight end on 494 F Flat, or an RPO alert read like Return RPO Alert Flat. Spanning 14 formations, 170 sets, and 258 plays, it covers the high-low concepts and quick outlets that punish Cover 3 cloud, soft squat corners, and any zone drop that vacates the sideline. Competitive players use this filter to build a scheme around cheap completions and clock control, then layer in curl and corner combos off the same route stems so defenders who jump the flat get beaten over the top.
