Mtn Drive Zig

Watch for two deep safeties at depth pre-snap, this is the classic Cover 4 shell that this play is designed to exploit through the zig sitting in the seam. If the strong safety rotates down into the box before the snap, expect a Cover 3 buzz look that can undercut the zig route with a robber technique, so be ready to check down to the drive route. User-controlled defenders sitting in the middle hook zone or lurking near the zig's break point are the biggest threat to this concept, since a good user read can jump the route and create a pick six opportunity. Linebacker depth at the snap matters, if they sink immediately into deep zone drops the drive route underneath becomes wide open, but if they stay shallow to defend the drive route the zig will have a clean throwing lane. Man coverage with no safety help over the top is where this play struggles most, since the zig has to fight through traffic in the bunch release and can get picked off by physical corners at the line.
