Comebacks

Off man coverage on the backside single receiver is the biggest tell that the comeback will be open, since the defender has to respect the vertical stem and cannot easily undercut the break. Cover 3 zone with corners sinking deep leaves the comeback routes sitting in the soft spot between the underneath zone defenders and the deep third, so watch for cornerback depth at the snap. User controlled defenders sitting on curl to flat zones can jump the trips side comebacks, so if you see a defender flashing outside toward the sideline early, redirect to the backside comeback or checkdown to the running back. Press man coverage on the outside receivers is the primary defense that shuts this down, since the receiver has to fight through the jam before even starting the route stem, delaying the timing of the comeback break. Watch linebacker depth pre-snap, if they are shallow and clearly keying the flat, the middle trips receiver route into that area will be contested, so lean on the outside comebacks instead.
