Innovators see things differently and in the case of Coach Coverdale, he has a knack for finding ways to make simple concepts look very complex to defenses. See his latest innovation here.

shamrocks“Inbounds plays” in basketball are used for two specific reasons. First, it is used to get an easy layup or clean shot for a shooter by their design. Secondly, they are used to get the team into their regular offense. We have taken that same concept and applied it to the football field to give us some “easy layups” that can easily transition us into our base offense.

Stack Formations:

When we signal for a “stacked” alignment by the RB and a run is part of the play call, we are using the RB’s “stacked” alignment as the football equivalent of an inbounds play. We can run this to either the boundary or the field and with or without some other kind of restraint.

In our system, “stack” tells the RB to:

Align directly behind the widest receiver if told to stack into the boundary

Align directly behind the first detached receiver (middle of 3) if to the field


The “easy layup” we’re looking to get from the stacked alignment before ‘getting into our regular offense’ is one of our “Now” screens. For us, that means “Raider” if the RB is to the boundary or “Saint” if he is to the field.

As you can see, we have been able to empower our RB and QB to use this concept to both create quick opportunities for “layups” while using the motion to move us into our base offense. This concept can be flexible to fit with about any scheme and can be added with just one additional signal or word. I hope that it can be a valuable concept for your team in the upcoming season. Thanks for your time and interest.
