What Is the Over Front Defense?

The Over Front Defense is a variation of the four-man defensive front that shifts the defensive line toward the strong side of the offensive formation. This alignment is intended to strengthen the defense against strong-side running plays while maintaining an effective four-man pass rush.

History

The Over Front evolved from traditional 4-3 defensive principles as coaches adjusted defensive line alignments to better match offensive strength. It remains a common front at every level of football.
