Defensive coordinators can get pulled into the wrong scoreboards.
One year, you are chasing improvement (“If we can go from 99th to 98th, that’s a win.”). The next year, you’re living on three-and-outs and barely seeing the red zone. And before you know it, a normal drive feels like failure.
Woody Blevins, Defensive Coordinator at Davidson College, says the fix is simple: re-teach the purpose of defense until your players can say it without thinking.
Purpose #1: Keep the offense from scoring
This is the non-negotiable. Your defense exists to prevent points.
That does not mean every series has to be a three-and-out. If the offense drives the ball and you hold them out of the end zone, you did the primary job. The standard is points allowed, not vibes.
Coaching note: When players equate “good defense” with “quick stop,” they start pressing. They lose leverage, freelance, and lose the plot.
Purpose #2: Gain possession of the ball
Blevins frames this as more than “takeaways.”
Yes, interceptions and forced fumbles count. But so do:
- Fourth-down stops
- Punt blocks
- Field goal blocks
If you get the ball back, you changed the game. And in most cases, you also achieved Purpose #1 along the way (you kept them from scoring).
Purpose #3: Score
Great defenses not only prevent points. They produce them.
Defensive touchdowns, scoop-and-scores, pick-sixes, blocked-kick returns, safeties. If your unit is going to be “attacking,” it has to be capable of turning possession into points.
Blevins’ line to players is blunt: if you lose a game, it is not enough to say, “We didn’t let them score much.” A great defense hunts all three purposes every week.
A simple teaching routine that exposes the gap fast
Blevins starts with a day-one question: “What is the purpose of defense?” Then he pushes it further:
- What is the purpose of offense?
- What is the purpose of being a DB?
- What is the purpose of being a D-lineman?
Most players can give you one answer. Some can give you two. Very few give you all three.
Philosophy in three layers: Mentality → Strategy → Tactics
Blevins outlines the foundation of defensive philosophy as a progression:
- Mentality (the space between the ears)
- Strategy (the plan and priorities)
- Tactics (scheme and technique)
Most staffs jump straight to tactics. Blevins’ point is that mentality has to be built first, or your tactics will not hold up under stress.
Practical translation: If your players don’t share a mentality, they won’t execute the same call the same way.
“If it’s not repeatable, it doesn’t exist.”
Blevins’ standard for “philosophy” is simple: if it is not written down and referenced constantly, it is not philosophy. It is just thoughts.

Put this on one page. Print it. Post it. Review it.
A) Our 3 purposes (verbatim)
- Prevent points
- Gain possession
- Score
B) Our mentality statements (3–5 bullets)
Examples: relentless effort, strain for the ball, play with composure, etc.
C) Our strategic priorities (3 bullets)
Examples: win 1st down, eliminate explosives, dominate the red zone, etc.
D) Our tactical pillars (3 bullets)
Examples: spill/box rules, pressure menu identity, coverage family rules, etc.
Where this came from (and why it’s worth digging into)
Blevins credits an older defensive resource for sharpening this “purpose” framework: The Radar Defense for Winning Football by Jules Yakapovich.

You just watched the free lesson: Woody Blevins’ 3 purposes of defense
- Keep the offense from scoring
- Gain possession of the ball
- Score
If you want what comes next, the full presentation shows you how he turns that “why” into an installable operating system — something your staff can teach the same way, and your players can execute under stress.
What you’ll get in the full Woody Blevins presentation
Coach Blevins takes you beyond “purpose” and into the pieces that make a defense repeatable:
- How he starts meetings (“the juice”) to get the room ready to learn, then ties it to long-term defensive growth (Chinese bamboo tree).
- How he uses philosophy to dictate how they operate, install, and even script practice — including a system that ensures his “pillars” get repped in equal proportion (not just “what we feel like”).
- The idea of vertical alignment: how you do one thing is how you do all things (including a story about a “fast team” holding slow meetings).
- His “cornerstones” structure: Purpose → Mentality → Strategy → Tactics (and what each layer controls).
- The Mentality layer with DEA (Discipline, Effort, Attitude) and why values have to be repeatable or they don’t really exist.
- The Strategy layer: attack + balance to nullify what the offense is trying to do.
- The Tactics layer: zone coverage, match coverage, and pressure — and his definition of pressure as pre-snap, on-snap, and post-snap (including D-line movement as a pressure tool).
- The “keep it simple” trap — and why his answer is concise → clarity → exponential building (complementary, not complex).
- The pandemic-era job/skill inventory staff exercise that changed how he teaches (and the warning: “similar but different” kills clarity).
- A practical D-line teaching progression: gap / stick / lag / shoot / face, plus how those families build stunts and pressures — with examples of how he labels and calls it.
