You can see his head looking straight downfield and directly at the safety. The corner who is covering the X receiver is playing outside leverage thinking he has inside help from the safety. The safety to the opposite side sees the play developing then races towards the middle of the field. You can see the play side safety moves up to take the dig route even though the linebackers are dropping back to take way that zone. This way the QB can lead the receiver towards the center of the field and away from the defender without worry. If the safety steps up the QB pretty much knows he is going deep as long as the receiver can gain a step with inside position on his defender. Once he knows the coverage he then reads the safety to see if he runs with the post or steps up to take away the dig route. The QB needs to get a read on the defense presnap or just after the snap to understand where the coverage is. Most teams consider an X receiver to be a great matchup against a lone zone corner across the field who is without safety help. Teams like to run this concept against cover 4 since it forces the playside safety to come up on the 12-14 yard dig which leaves the post in a one on one matchup against the outside corner who cannot be assisted by backside safety. The concept gives teams a chance (with the proper read) to attack deep against a defense but also allows for a high percentage short (underneath) route if the read is not there for the deep ball. The supplementary route is usually a shallow crossing route from the opposite side of the primary routes. As long as the two main routes are run next to each other it is generally considered a Mills concept in route design. It also encompasses a third supplementary route underneath. It can be run at one or two safety defensive schemes and consists of two primary routes, the (X) which is a post and an in breaking route (F) run in front of the safeties. The Mills passing concept creates two high-low reads for the QB by putting the deep safeties and linebackers in conflict. (Play diagrams courtesy of the Weekly Spiral) If the receiver and QB are solid in their jobs it makes it very tough for the defense to stop the play without some adjustments to their normal defensive schemes. What we are trying to show is what the receivers need to do along with what the QB is reading (in the defense) on the play. These are some basic passing schemes but add a little more complexity than our prior two schemes. In our quest to familiarize our readers with some of the more widely used passing schemes continues with a look at the Mills and Smash concepts.
