Levels Mills

Watch the backside safety depth pre-snap, if he is shaded to the trips side or shows two high, the Mills post has room to work behind him once the dig clears the middle. Key the flat defender and the underneath linebacker on the trips side, this play is designed to put them in a horizontal stretch between the in route and the dig. If the defense shows Cover 3 or a single high rotation, the post can get squeezed by the deep middle defender, so lean on the levels side instead of forcing the Mills throw. User lurk defenders sitting in the intermediate middle zone can jump the dig route, so track any manually controlled linebacker or safety drifting toward that landmark before pulling the trigger. Man coverage with no safety help over the top is the biggest vulnerability, since both the post and the dig can separate vertically against trailing defenders, but a disguised blitz can beat this play before routes develop, so respect delayed pressure off the edge.
