Finding the Actions That Actually Drive Impact
By Scott Krotee
Most teams still evaluate players using the same traditional statistics: goals, assists, shots, saves, and tackles. These numbers matter, but they only tell part of the story. They often capture the end result of a possession, not the actions that actually created, protected, or prevented the moment.
The Three Pillars of Player Impact
Measure what matters: the actions that improve, protect, and create value.
A Player May Not Appear in the Box Score
A player may not score.
A player may not assist.
A player may not appear in the box score.
But they may have broken a defensive line, progressed the ball into a dangerous area, won possession in transition, disrupted the opponent's buildup, or prevented a high-value attacking chance.
That is impact.
And most traditional statistics miss it.
The Better Question
Instead of only asking:
- Who scored?
- Who assisted?
- Who took the shot?
Teams should also be asking:
- Did this player improve our possession?
- Did this player hurt our possession?
- Did this player disrupt the opponent's possession?
- Did this player cause a defensive breakdown?
This is where a simple possession-based evaluation model becomes extremely powerful.
You do not need a million-dollar data science department to start measuring player impact. You do not need a full optical tracking system. You do not need to build a complex probability model from scratch.
You can begin with structured event tagging.
And when done correctly, that simple system can deliver a powerful analytics framework for your team.
What Is Possession Value?
Possession Value, or PV, measures how much an action increases or decreases a team's likelihood of scoring during a possession.
In simple terms:
How much did this action improve or hurt the possession?
For example, a player may break a defensive line with a pass.
That action may not be an assist.
It may not even appear in the traditional box score.
But it may dramatically increase the probability of scoring.
Traditional stats often miss that type of contribution.
Possession Value captures it.
Why Traditional Player Rankings Fall Short
Most player ranking systems still start with a formula that looks something like this:
Player Ranking = Goals + Assists + Shots
That can be useful, but it is incomplete.
Goals and assists are outcome-based. They reward the final action in the chain.
But games are often decided by the sequence of actions that happen before the outcome.
A midfielder who repeatedly breaks pressure may create the conditions for a goal. A center back who consistently progresses the ball may change the entire rhythm of a match. A defensive midfielder who destroys opponent possessions may prevent chances before they ever become shots.
Traditional rankings often fail to capture these players.
A better model starts to look like this:
Player Ranking = Possession Value Added + Defensive Disruption Value + Transition Impact
That becomes a much better signal.
It captures who is creating value, who is protecting value, and who is changing momentum.
Offensive Possession Value
Offensive Possession Value measures whether a player's action improved or hurt your team's possession.
The key question is:
Did this player improve our possession, keep it alive, or increase our chance of creating a scoring opportunity?
This can be tracked through two concepts:
PV+
PV+ represents positive possession value added.
Examples may include:
- Line-breaking pass
- Progressive carry
- Successful dribble
- Key pass
- Entry into the final third
- Switch of play that creates space
- Clean pass under pressure
- Maintaining possession in a difficult moment
- Creating a higher-value attacking situation
These actions may not always lead directly to a goal or assist, but they move the team closer to creating a scoring opportunity.
PV−
PV− represents possession value lost.
Examples may include:
- Turnover
- Failed dribble
- Poor pass under little pressure
- Bad decision in buildup
- Forced ball into pressure
- Lost possession in a dangerous area
- Killing a promising attack
- Poor first touch that breaks rhythm
These actions reduce the quality of the possession, slow the attack, or end the possession entirely.
This is already a better signal than simply counting goals, assists, and shots because it captures the actions that shape the possession before the final outcome.
Defensive Disruption
Defense should not only be measured by tackles, clearances, or blocked shots.
Those moments matter, but they do not fully capture defensive impact.
The better question is:
Did this player disrupt or destroy the opponent's possession?
That is Defensive Disruption.
Just like Offensive Possession Value, Defensive Disruption can be split into positive and negative actions.
DD+
DD+ represents positive defensive disruption.
Examples may include:
- Interception
- Successful press
- Tackle
- Forced turnover
- Winning a duel
- Blocking a passing lane
- Preventing forward progression
- Delaying a counterattack
- Forcing play backward
- Recovering possession in transition
These actions stop the opponent from building value in their possession.
DD−
DD− represents negative defensive disruption or defensive breakdown.
Examples may include:
- Missed tackle
- Lost duel
- Poor defensive positioning
- Failed press
- Defensive turnover
- Losing a runner
- Allowing easy progression
- Breaking team shape
- Poor recovery run
- Failing to track a dangerous action
These actions allow the opponent to increase the value of their possession.
By separating positive defensive disruption from defensive breakdowns, coaches can better understand who is actually helping the team without the ball.
A Simple Tagging System
Teams do not need to manually build a complex possession value model from scratch.
StatLink already supports a simple tagging framework that captures player actions as:
- Good
- Neutral
- Poor
In some workflows, this can be simplified even further into:
- Good action
- Poor action
That simplicity is the point.
A coach, analyst, or staff member can tag whether an offensive or defensive action helped or hurt the team. From there, StatLink models and ranks those outcomes into a predictive impact score from 0–100.
For offensive moments, the question becomes:
Did this player improve the possession, keep it alive, or increase the team's chance of creating a scoring opportunity?
A Good offensive tag may represent possession value added.
A Neutral offensive tag may represent a possession action that maintained value without meaningfully increasing or decreasing it.
A Poor offensive tag may represent possession value lost.
For defensive moments, the question becomes:
Did this player disrupt the opponent's possession, win the ball, delay the attack, or prevent danger?
A Good defensive tag may represent defensive disruption.
A Neutral defensive tag may represent a stable defensive action that maintained structure without a major positive or negative outcome.
A Poor defensive tag may represent a defensive breakdown.
The tagging system stays simple for the user, while the modeling behind the scenes turns those actions into a more meaningful impact signal.

Turning Actions Into Impact
Once these events are tracked, teams can begin to understand player value in a much more complete way.
If a team wanted to derive individual metrics, they could look at things like:
Offensive Value Added / 90
How often a player improves attacking possessions over a full match.
Possession Value Lost / 90
How often a player hurts, slows, or ends possessions.
Defensive Disruption / 90
How often a player disrupts, delays, or wins opponent possessions.
Defensive Breakdown / 90
How often a player contributes to opponent progression or chance creation.
Transition Impact
How often a player influences momentum shifts between attack and defense.
These metrics provide a much clearer picture of overall player value.
Instead of asking only who scored, the team can ask:
- Who consistently improves our possessions?
- Who disrupts opponent possessions?
- Who creates momentum?
- Who is quietly helping us win?
- Who is quietly hurting us?
But the important point is this:
StatLink already does the heavy lifting.
Instead of forcing coaches to manually calculate PV+, PV−, DD+, DD−, or build formulas themselves, StatLink models those tagged outcomes and translates them into a predictive impact score.
From Simple Tags to a Predictive Impact Score
At a basic theoretical level, an impact model could be thought of like this:
Impact = PV+ + Defensive Disruption − PV Loss
Or more specifically:
Total Impact = Offensive Possession Value + Defensive Disruption
Where:
Offensive Possession Value = PV+ − PV−
And:
Defensive Disruption = DD+ − DD−
This creates a more complete picture of player impact.
It rewards players who improve possessions.
It rewards players who disrupt opponents.
It accounts for players who repeatedly lose possession or create defensive breakdowns.
But inside StatLink, teams do not have to manage these calculations manually.
The platform takes structured Good, Neutral, and Poor actions and ranks players through a predictive impact score from 0–100.
That creates a much stronger signal than traditional box score statistics alone.
This is where the power of StatLink comes in:
Simple inputs. Powerful modeling. Clear player impact.
Why This Is Sneaky Powerful
This model captures players that traditional stats often overlook.
- The build-up midfielder who consistently breaks lines.
- The center back who progresses the ball under pressure.
- The fullback who prevents dangerous transitions.
- The defensive midfielder who destroys opponent possessions before they become chances.
- The forward who presses intelligently and forces turnovers.
- The winger who consistently moves the ball into dangerous areas but does not always get the assist.
These players influence the game long before the shot occurs.
Traditional statistics often fail to recognize them.
Possession Value and Defensive Disruption help reveal their true impact.
You Do Not Need a Full Tracking Lab
Many teams assume this type of analysis requires elite infrastructure.
- Optical tracking.
- Computer vision.
- Massive event datasets.
- A full data science team.
Those tools are powerful, but they are not required to start.
Teams can approximate possession value today using structured event tagging.
That is the practical advantage.
A simple framework, applied consistently, can give coaches a clearer understanding of player impact without overwhelming the staff or budget.
This is exactly where StatLink fits.
StatLink allows teams to structure, score, visualize, and compare these actions in a way that is easy to understand and act on.
The goal is not to drown coaches in data.
The goal is to help them make better decisions.
The Next Step: The StatLink Impact Index
At StatLink, this framework points toward something bigger:
The StatLink Impact Index.
A core ranking metric designed to capture the players who:
- Improve attacking possessions
- Limit possession loss
- Disrupt opponent possessions
- Prevent defensive breakdowns
- Influence transition moments
- Drive overall team impact
Instead of ranking players only by goals, assists, and shots, the StatLink Impact Index creates a more complete view of performance.
It answers the question every coach actually cares about:
Who is helping us win?
That is the difference between tracking stats and measuring impact.
Built Across Sports
The best part is that this framework is not limited to soccer.
The same logic can apply across multiple sports.
Soccer
Who improves possession and disrupts opponent buildup?
Hockey
Who creates offensive zone value and breaks opponent possessions?
Lacrosse
Who improves attacking sequences and forces turnovers?
Basketball
Who creates possession value through passing, spacing, defense, and transition?
Different sports. Same principle.
Measure the actions that increase your team's chance of scoring and decrease the opponent's chance of scoring.
That is impact.
Final Thought
Goals and assists will always matter.
But the future of performance analysis lies in understanding the actions that lead to those moments.
A simple possession value and defensive disruption model helps teams find the players who consistently create value, prevent danger, and influence winning.
You do not need a million-dollar analytics department to start.
You need a clear framework.
You need consistent tagging.
You need a system that turns actions into insight.
That is what StatLink is building.
Because player rankings should not just tell you who finished the play.
They should tell you who changed the game.
Key Takeaways
- Possession Value (PV) measures whether a player's action improves or hurts the team's possession through positive (PV+) and negative (PV−) actions.
- Defensive Disruption (DD) captures how a player stops opponent possessions (DD+) or creates defensive breakdowns (DD−), not just tackles and clearances.
- Simple tagging systems using Good/Neutral/Poor categories can translate into predictive impact scores (0-100) without expensive infrastructure.
- Total Impact = Offensive Possession Value + Defensive Disruption provides a more complete picture than traditional box score statistics alone.
