Insider Knowledge

Terminology
ShotExpected Goal Value (xG Value)

From the casual term 'shot,' experts consider the xG Value to assess the likelihood that a shot will result in a goal based on location and context.

GoalExpected Goals (xG)

Fans call any scoring event a 'goal,' whereas insiders use xG to measure the probability of scoring from a given chance, reflecting shot quality rather than just outcomes.

PassExpected Pass Completion (xPass)

Casual observers refer simply to a 'pass,' while insiders quantify the quality and likelihood of completion using xPass metrics to better evaluate passing performance.

TacticsExpected Threat (xT)

Fans discuss tactics in a general sense, while analysts use xT to evaluate how specific actions increase the team's chance of scoring.

FoulFouling Impact

Outside observers see fouls as just penalties, but insiders analyze fouling impact to understand how fouls affect game momentum and field position.

AssistKey Pass

While casual fans note the assist, insiders value 'key passes' that create scoring opportunities even if they don't directly result in goals.

Player's ValuePlayer Contribution Model

Fans think in terms of transfer fees or fame, but insiders use models that quantify player contribution based on data-driven measures.

DefensePressing Intensity

Casual fans talk about defending generally, but insiders measure pressing intensity to quantify how aggressively a team applies pressure.

Game OutcomeWin Probability Model (WPM)

Casual observers state wins and losses, while insiders use WPM to calculate the changing probability of a team winning as the game progresses.

Player PositionHeatmap

Observers see player roles in broad terms, whereas insiders use heatmaps to visualize precise positioning and movement patterns on the pitch.

Greeting Salutations
Example Conversation
Insider
What's the xG?
Outsider
Huh? What's that mean?
Insider
It's short for 'expected goals,' a way we estimate scoring chances to understand how well a team creates opportunities.
Outsider
Oh, so you mean like how good their chances really are?
Insider
Exactly! It's a quick way to start conversations about match quality.
Cultural Context
This asymmetric greeting uses a central metric in football analytics, signaling insider knowledge and opening debates over team performance.
Inside Jokes

"That was a negative xG moment."

A humorous way analysts describe a very low-probability chance which ended in a goal, poking fun at how statistics can't predict everything perfectly.

"Packing more players than a Tetris game."

A lighthearted exaggeration about a team's ability to pass through opponent lines, comparing the tactical situation to the famous puzzle game's complexity.
Facts & Sayings

xG

Expected Goals, a statistical measure of the quality of scoring chances and the likelihood of those chances resulting in goals.

PPDA

Passes Per Defensive Action, a metric that quantifies how aggressively a team presses by counting the number of passes allowed per defensive action.

Packing

The act of bypassing opponent players with passes, 'packing' refers to the number of opponents bypassed by a single pass or run, indicating passing effectiveness.

Data-driven scouting

Refers to scouting players or tactics primarily based on quantitative metrics and analytics rather than subjective observation.
Unwritten Rules

Always cite data sources and methodologies transparently.

Credibility depends on openness about how metrics are calculated and the origins of datasets, fostering trust and reproducibility.

Respect traditional football knowledge while challenging it.

Balance is crucial; pure data rejection frustrates insiders, but arrogant dismissal of experience alienates traditionalists.

Use jargon carefully when communicating with non-analysts.

Using excessive technical language can isolate newcomers; effective communication bridges the gap between data experts and football fans.

Engage in open collaboration rather than proprietary gatekeeping.

Sharing code, datasets, and insights is a cultural expectation that accelerates collective progress in the field.

First Steps & Resources

Get-Started Steps
Time to basics: 2-3 weeks
1

Learn Football Analytics Basics

2-3 hoursBasic
Summary: Study core concepts: expected goals, passing networks, and key metrics in football analytics.
Details: Start by familiarizing yourself with the foundational concepts and terminology of football analytics. This includes understanding metrics like expected goals (xG), expected assists (xA), passing networks, possession value models, and player performance indicators. Read introductory articles, glossaries, and explainer videos to grasp how these metrics are calculated and applied. Beginners often struggle with jargon and statistical concepts, so take time to look up unfamiliar terms and revisit explanations as needed. Focus on understanding the 'why' behind each metric—how it informs tactical decisions or player evaluation. This step is crucial because it builds the vocabulary and conceptual framework you'll need to engage with the community and interpret analyses. To evaluate your progress, try explaining xG or another metric to someone else, or summarize a match report that uses analytics.
2

Explore Public Football Data

1-2 hoursBasic
Summary: Download open football datasets and browse them to understand their structure and contents.
Details: Accessing and exploring real football data is a key rite of passage in this bubble. Seek out open-source datasets—such as match event data, player stats, or tracking data—available from public repositories or community projects. Download a dataset and open it in spreadsheet software or a data visualization tool. Examine the columns, data types, and sample entries. Beginners often feel overwhelmed by the volume and complexity of data, so start small: focus on one match or player, and look for patterns or anomalies. Try to answer simple questions, like 'How many shots did a team take?' or 'Who completed the most passes?' This hands-on familiarity is essential for later analysis and helps demystify the data. Progress is measured by your comfort in navigating the dataset and extracting basic insights.
3

Join Analytics Community Discussions

2-3 hoursBasic
Summary: Participate in online forums or social media groups focused on football analytics discussions and sharing.
Details: Engaging with the football analytics community is vital for learning and growth. Join online forums, social media groups, or discussion threads where enthusiasts and professionals share analyses, debate findings, and post resources. Start by reading existing threads to observe the tone, common topics, and etiquette. When comfortable, introduce yourself and ask beginner questions or comment on analyses. Avoid spamming or asking for proprietary data; instead, show curiosity and willingness to learn. Many beginners hesitate to participate, fearing their questions are too basic—remember, most communities welcome newcomers and value thoughtful engagement. This step helps you stay updated on trends, find mentors, and get feedback on your ideas. Progress is evident when you can contribute meaningfully to discussions or receive responses to your questions.

Misconception #2

Analysts just look at numbers and ignore on-field realities.

Reality

Analysts combine quantitative data with qualitative knowledge of football to interpret data in the context of game situations and tactics.

Misconception #3

Advanced metrics like xG are a guaranteed predictor of future matches.

Reality

Metrics are probabilistic tools that guide understanding but never predict exact outcomes due to football's inherent unpredictability.
