→ Which skills prop them up vs cost them
→ Where your edges actually exist
→ How volatile those edges are (stability matters)
→ Which 2-3 fights are worth picking
Most of the board is noise. A few rows light up. That's the short list.

It identifies which edges are decision-relevant and which ones disappear under pressure.
Not 'they're bad at digging'—but 'their in-system dig conversion edge means long rallies will be expensive.'

If they've built resilience out of system—stronger pins, cleaner emergency tempo—then 'getting them OOS' isn't a win condition. It's just a state of play.

Then the match starts and the scoreboard doesn't move the way it's supposed to.
Not because you were wrong. Because you were incomplete.

It's knowing which of those things you can realistically exploit—and which ones carry enough leverage to be worth the effort.
Not every weakness is worth your time.

→ "We need to work on everything" becomes "here's where our resources yield most impact"
→ Recruiting debates become explicit tradeoffs

Not "your dig percentage is bad"—but "your dig quality is costing 16 points of win probability, and improving it gives the largest single-leverage payoff."

They're not swinging more. They're better at stabilizing rallies and generating clean offensive opportunities.

Gain? +7.0%
Less than improving dig quality alone.
Why? Improvements interact. Spreading resources dilutes impact on your most critical weakness. Focus matters.

Improve dig quality from bottom-tier to average: +16.6% win probability. One skill moves you from scraping by to genuinely competitive.
Improve passing to average: +8.8%
Improve serving: +4.1%

The question isn't "what are we bad at?" It's "which weaknesses are actually expensive?"

The model doesn't penalize aggression. It penalizes survival.
Before showing any of this, the model had to prove it was honest.

This isn't about spectacular plays. It's about digs that consistently return rallies to neutral or better.
Attack volume showed up negatively.

In-system dig percentage is the strongest single driver. By a lot.

Attacking is how points end. Access to in-system offense is where leverage is created.
One thing I expected to dominate—and didn't—was attack quality on its own.

They're about how often teams get to attack cleanly.
In-system digs. Freeballs received. Pass rating. Three of the four most influential metrics are doing the same job: deciding whether the offense operates in-system or just survives.

That's a different class of question. And it requires a different tool: logistic regression.
Not fixed thresholds → probabilities.
Not one-size-fits-all → adapts to how teams actually win.
