When the run game breaks open early, panic is a natural reaction. The instinct is to scrap the plan, dial up pressure, or shift into emergency mode. But disciplined defenses don\u2019t live in chaos\u2014they adjust with purpose. Great coaches don\u2019t chase solutions\u2014they follow a process. Run defense isn’t fixed by desperation. It\u2019s fixed by alignment, technique, and clarity\u2014one step at a time.<\/p>\n\n\n\n
At North Central College, a Division III powerhouse with three national titles in five years, defensive coach Kalus Murphy explains how to approach run defense with patience and structure. In fact, Coach Murphy teaches a stepwise run defense adjustment<\/strong> process that simplifies decision-making and protects the integrity of the overall defense.<\/p>\n\n\n\n
\u201cWhat was kind of teaching us was\u2026 you get creased in the run game and immediately think, okay, I got to change something schematically. Instead\u2026 trust your scheme.\u201d<\/p>\n\n\n\n
\u2014 Coach Kalus Murphy (15:00)<\/p>\n\n\n\n
Let\u2019s break down this process\u2014and how you can apply it at any level.<\/p>\n\n\n\n
Step 1: Fix Technique Before Anything Else<\/strong><\/h3>\n\n\n\n
Before you even consider adjusting alignments or coverage, evaluate whether the breakdown stems from poor fundamentals. Missed fits, poor pad level, or failure to spill the ball properly can create big plays regardless of the scheme.<\/p>\n\n\n\n
Coach Murphy describes a typical mistake that seems schematic but isn\u2019t:<\/p>\n\n\n\n
\u201cHe\u2019s not getting underneath the puller and spilling it out to speed. And that was the issue.\u201d<\/p>\n\n\n\n
\u2014 Coach Kalus Murphy (15:57)<\/p>\n\n\n\n
In other words, the play was defended properly on paper, but execution failed. Review film and coach individual reps before altering the system.<\/p>\n\n\n\n<\/figure>\n\n\n\n
Step 2: Adjust Fronts with Purpose<\/strong><\/h3>\n\n\n\n
If the issue isn\u2019t technique, then it may be time to adjust the front. Small tweaks in alignment can go a long way in helping your defenders gain leverage.<\/p>\n\n\n\n
\u201cMaybe it\u2019s, hey, we got to cheat him to a four-eye and just over-cheat that front.\u201d<\/p>\n\n\n\n
\u2014 Coach Kalus Murphy (16:27)<\/p>\n\n\n\n
Step 3: Use Coverage to Modify Spacing<\/strong><\/p>\n\n\n\n
When technique and fronts don\u2019t get it done, coverage can help you change the math. Adjusting coverage isn\u2019t just about the pass\u2014it affects how many bodies you\u2019ve got in the run fit and where they show up.<\/p>\n\n\n\n
Rotate a safety down. Spin the coverage. Bump from two-high to one-high. Each call changes how the offense sees the box\u2014and how you support it.<\/p>\n\n\n\n
Murphy\u2019s approach is subtle but effective. Reduce the end from a 9 to a 6 or 6i to get a stronger edge on counter. Shade the defensive tackle to gain better angles on zone. Small tweaks like these can close space without blowing up your structure.<\/p>\n\n\n\n
Coach Murphy explains:<\/p>\n\n\n\n
\u201cIn quarters\u2026 there are nine available players\u2026 Cover three\u2026 leaves you eight\u2026 Cover two\u2026 now you\u2019re truly playing with seven-man spacing.\u201d<\/p>\n\n\n\n
\u2014 Coach Kalus Murphy (17:30)<\/p>\n\n\n\n
This concept\u2014how many defenders are \u201cin the fit\u201d\u2014guides your coverage call. A quarter-based defense allows maximum run support. A move to cover three or cover two reduces that support but may increase pass protection or disguise. Knowing when and how to shift spacing is essential to defending versatile offenses.<\/p>\n\n\n\n
Final Step: Apply Stunts and Blitzes\u2014Last<\/strong><\/h3>\n\n\n\n
Only after evaluating technique, fronts, and coverage should you consider movement games and pressures. Stunts like ET (end-tackle) or TE (tackle-end) can disrupt zone plays, while targeted blitzes can overwhelm protections\u2014but they come with risk. Coach Murphy reminds us to build adjustments progressively<\/strong>, not emotionally.<\/p>\n\n\n\n
\u201cEven then you\u2019re getting outgunned like that\u2026 that\u2019s now a physical problem.\u201d<\/p>\n\n\n\n
\u2014 Coach Kalus Murphy (18:26)<\/p>\n\n\n\n
Conclusion<\/strong><\/h3>\n\n\n\n
Implementing stepwise run defense adjustments<\/strong> empowers your team to stay grounded and resilient. Instead of scrambling for answers mid-game, you\u2019ll have a structured system that restores control\u2014starting with fundamentals and ending with high-impact tactics only when necessary.<\/p>\n\n\n\n
It\u2019s not about how quickly you can change your defense. It\u2019s about how confidently you can fix problems without abandoning your identity<\/strong>. Trust the process\u2014and teach your players to do the same.<\/p>\n\n\n\n
