Plain explanations of the analytics and tactical terms that show up in modern football coverage.

Glossary · Analysis
Shot quality is total xG divided by shots: the average chance a team creates or allows. Why volume and quality are separate levers, and where the number breaks down.
Glossary · Analysis
Possession value models such as xT, VAEP and OBV put a goal-probability value on every pass, carry and tackle, not just shots. How they differ and where they break down.
Glossary · Analysis
A pass network plots each player at their average position and links them by how often they pass to each other. Here is how it is built and how to read one.
Glossary · Analysis
Build-up play is how a team moves the ball from goalkeeper and defenders into midfield against a press. Here's how it's shaped, measured and misread.
Glossary · Analysis
Transitions are the seconds after possession changes hands. Here's why attacking and defensive transitions produce so many chances, and how teams plan for both.
Glossary · Analysis
Pressing triggers are pre-agreed cues, like a bad touch or a back pass, that tell a team to press together. Here's how they work and what the stats miss.
Glossary · Analysis
Rest defence is the shape a team keeps behind the ball while it attacks. Here's how 2+1 and 3+2 structures work, how it pairs with counterpressing, and what data shows.
Glossary · Analysis
A third man run uses a bounce pass to reach a runner the first passer could not find directly. Here's how it works, why it beats compact defences, and its limits.
Glossary · Analysis
Zone 14 is the central area just outside the penalty box on an 18-zone pitch grid. Here is where the idea came from, why coaches care, and what it misses.
Glossary · Analysis
A line-breaking pass travels through or beyond a line of opposition players. Here's how analysts detect it, why coaches prize it, and what the count leaves out.
Glossary · Essay
Football didn't invent a way to rate team strength between matches. It borrowed one from chess, and it's turned out to travel remarkably well.
Glossary · Essay
Chances don't come from nowhere. Box entries count how often a team actually gets the ball into the penalty area, by pass or by carry.
Glossary · Essay
Closing down an opponent doesn't always win the ball back. Pressures count every attempt; regains count only the ones that actually worked.
Glossary · Essay
Not every completed pass matters equally. Deep completions only count the ones that land close enough to goal to actually threaten it.
Glossary · Essay
Two teams can complete the same number of passes and advance the ball at completely different speeds. Verticality measures how directly a team goes toward goal.
Glossary · Essay
A win is three points whether it was deserved or not. Expected points strips the randomness out of results and asks what a team's performances actually merited.
Glossary · Essay
Football is often decided by moments where one side simply has more players than the other in a small area. An overload is how teams engineer that advantage on purpose.
Glossary · Essay
Not every team wants the ball high up the pitch. A low block gives up territory on purpose, packing numbers near goal and forcing the opponent to solve a crowded box.
Glossary · Essay
Football commentary talks about wings and the center. The half-space is the corridor in between, and it's where a huge share of modern attacking play actually happens.
Glossary · Essay
Losing the ball used to mean stopping to reorganize. Gegenpressing treats the moment of loss as the best chance to win it straight back, before the opponent can even think.
Glossary · Essay
Assists only credit the final pass before a goal. Shot-creating actions count the two plays before every shot, crediting the buildup that assist totals miss entirely.
Glossary · Essay
Possession counts every touch the same, in your own box or the opponent's. Field tilt measures territory directly, by tracking where the passing actually happens.
Glossary · Essay
A short pass through the right gap can do more damage than a long ball into open space. Packing counts how many defenders a single pass or dribble actually eliminates.
Glossary · Essay
Pre-shot xG can't see where the ball actually went. Post-shot xG grades a shot after it's struck, making it the clearest public way to rate a goalkeeper's shot-stopping.
Glossary · Essay
Penalties inflate a striker's expected goals in a way that has nothing to do with open play. Non-penalty xG strips them out for a cleaner read on real chance creation.
Glossary · Essay
Possession share says who has the ball more, not what they do with it. Progressive passes and carries count how often the ball actually moves toward goal.
Glossary · Essay
Distance up the pitch isn't the same as danger created. Expected threat values every pass and carry by how much it actually raises the chance of a goal.
Glossary · Essay
Pressing intensity is hard to judge by eye alone. PPDA counts how many passes a team allows before winning the ball back, turning a vague impression into a comparable number.
Glossary · Essay
An assist depends on someone else finishing the chance. Expected assists scores the pass itself, showing who is creating danger even when the strikers around them are missing it.
Glossary · Essay
Every shot carries a probability of becoming a goal. Expected goals puts a number on that probability, and gets misread more often than almost any other stat in the modern game.
