What Are Advanced Run Fits and Why They Matter
Advanced run fits = making defenders who DON'T have run assignments help stop the run anyway.
Here's the deal. Most defenses leave gaps. Your outside corners and safeties often have ZERO run responsibility. They're sitting in deep coverage while running backs gash you for 8+ yards.
The fix? Hard flats.
Put defenders without run fits in hard flat zones. They'll play their assignment first. But now their assignment brings them DOWNHILL instead of backing up into coverage.
Key insight: Defenders always play their assignment first. If that assignment is a hard flat, they're coming to the line of scrimmage. Boom. Instant run support.
How to Identify Defenders Without Run Fits
Press Right Trigger + B on Xbox (R2 + Circle on PlayStation) to see your run fits.
Look for defenders with NO colored assignment:
- Outside corners in Cover 4
- Deep safeties in most coverages
- Nickel defenders in certain formations
These guys are your targets. They're going to backpedal into coverage while the run game destroys you.
Example: Cover 4 defense. Your outside right corner has no run fit. Offense runs stretch right. This corner backpedals for deep quarter coverage. Meanwhile, your force defender (inside linebacker) can't set the edge alone.
Result? Easy yards.
How to Set Up Hard Flat Run Fits
Step 1: Identify defenders without run fits using the run fit display
Step 2: Put these defenders in hard flat zones
- Select the defender
- Choose hard flat coverage
- Do this for ALL defenders without run assignments
Step 3: Watch them come downhill automatically
They're not trying to play run. They're playing their pass assignment. But that assignment now brings them toward the line of scrimmage.
Specific Example: Cover 4 Fix
Your outside corners in Cover 4 have no run fits. Put both in hard flats.
Now when they run stretch plays:
- Corner comes downhill instead of backpedaling
- Sets the edge for you
- Makes the tackle or forces it inside
Same concept works for safeties: put that deep safety in a hard flat, now he's attacking the line.
When to Use Advanced Run Fits
Against run-heavy opponents, if they're pounding the rock, you need every defender involved
In obvious running situations, 3rd and short, goal line, end of game
When your base run fits aren't working: getting gashed on the edges? Add hard flat help.
Against stretch plays specifically. These attack the edges where you're most vulnerable
Formation-Specific Usage
Cover 4: Both outside corners need hard flats
Cover 3: Deep safeties can go to hard flats
Nickel defenses: Extra DB usually has no run fit. Perfect hard flat candidate
Why This Strategy Works
It's all about assignment priority.
Defenders play their assignment FIRST. If they don't have a run fit, they're playing pass coverage first.
Hard flats change the math:
- Old way: Defender backpedals into deep coverage
- New way: Defender attacks the flat (toward the line)
- Result: Accidental run support
The beauty, you're not changing the defender's behavior. You're just giving them a different assignment that helps vs. run.
What Counters Advanced Run Fits
Quick passing game, if you put everyone in hard flats, you're vulnerable over the top
Play action, your hard flat defenders might bite on run fakes
Screens and slants. Attacking the areas you just vacated
Counter strategy: Don't overdo it. Pick 1-2 key defenders without run fits. Don't put your entire secondary in hard flats.
Common Mistakes with Run Fits
Mistake #1: Putting defenders who ALREADY have run fits in hard flats
Check your run fits first. Don't mess with guys already assigned.
Mistake #2: Going overboard
You still need SOME deep coverage. Pick your spots.
Mistake #3: Forgetting about pass concepts
Hard flats help vs. run but create pass vulnerabilities. Balance it out.
Mistake #4: Not adjusting to formations
Different formations = different defenders without run fits. Stay flexible.
Advanced Tips
Mix your coverage. One hard flat, one deep safety. Don't be predictable.
Watch the game flow. If they're throwing over your hard flats, back off.
Use with other adjustments. Hard flats work great with pinch/crash line calls.
This isn't about the system doing everything for you. It's about YOU making smart adjustments that turn coverage defenders into run stoppers.
