How Snag works

Three-receiver triangle.
Inside slot runs the 'snag' (spot route at 5-6 yds, settling); outside runs a corner over the top; back to the flat.
Triangle stretches the flat defender high-low AND the corner inside-out.

Call sheet

Defensive lookVersatile triangle vs Cover 1 or Cover 3 — three options at three depths.
Game planStrong on 2nd-and-medium when you need positive yards regardless of look.
PressureRead the triangle low-to-high against pressure and inside-out against spot-drop zone.
Defensive lookVs man, tighten the bunch to manufacture traffic; vs zone, widen the point receiver enough to preserve all three windows.
Red zoneNear the goal line, shorten the corner break and settle the snag just beyond the goal line.

Pre-snap to post-snap

Cover 3 — The flats — four underneath defenders can't cover all five underneath zones (curl-flat / slant-flat)
Cover 4 — Underneath and the flats — only three short defenders (stick / snag / quick game)

Troubleshooting

Avoid it against a hard two-man bracket on the three-receiver side or pressure that arrives before the corner route can clear the triangle.
A squat corner plus an outside-leverage flat defender can squeeze both short answers, so keep a backside outlet when that rotation is likely.
Snag receiver doesn't sit in the soft spot; either keeps running or settles too deep.
Corner route flattens out; should be a true corner break at 45°, not a deep out.
RB flat doesn't get vertical leverage on the linebacker; flat should be back to the sideline at 0-3 yards.
