Player statistics are the raw material of data-led football betting. They tell you what a player has done in recent matches (how many shots, goals, assists, fouls) and from that you can start to build a probabilistic picture of what they might do next.
Understanding what each stat actually measures, and where it misleads, is the starting point before applying any more sophisticated analysis.

The core stats and what they tell you
Goals scored. The most obvious metric. Useful for assessing strikers as goalscorer bet builder legs, but volatile over small samples. A striker can go six matches without scoring and still be generating good opportunities.
Assists. Less predictable than goals, and heavily dependent on a player's role and teammates. A high assist rate often reflects good positioning and vision but can also reflect playing behind a prolific striker.
Total shots. How many times a player attempted a shot, regardless of whether it hit the target. Higher shot volume generally means more chances to score, but efficiency matters too. See expected goals (xG) for a better measure of shot quality.
Shots on target. A subset of total shots, meaning attempts that required a save or went in. More predictive of goals than total shots alone because it filters out wild attempts that were never threatening.
Fouls committed. Useful for yellow card bets and cards-related bet builder legs. Some players commit high volumes of fouls consistently; others are clean.
Fouls drawn. How often a player wins a foul. Relevant for players who might be booked in frustration by defenders, and for free kick and set piece contexts.
Yellow and red cards. Directly relevant to cards markets. Some players have structural tendencies towards being booked, such as high press intensity and aggressive challenges, that show up consistently in the data.
Tackles. A defensive stat that matters for midfielder-cards markets and some bet builder legs.

Raw stats vs per-game rates
If you are comparing two players who have played different numbers of matches, total stats are misleading. Always use per-game rates (or per-90-minute stats) when comparing across players.
A player with eight goals in 30 games is less impressive than one with six goals in 14 games, even though the raw totals look different.

Why raw averages do not tell the full story
Three problems with relying on raw player averages alone:
Opposition quality varies. A player's shot average against bottom-half sides will be higher than against top-four defences. Raw averages blend all opponents together. SignalRates on BetSignals adjusts for this.
Small samples are unreliable. Six or eight games is not enough to draw firm conclusions. A player who has scored in four of their last six might be genuinely hot, or might have had a fortunate run. Bayesian approaches, blending the player's own data with the league average, help correct for this.
Role and tactics change. A player deployed centrally in a 4-3-3 generates very different stats from the same player playing as a wide midfielder in a 4-5-1. A change of manager or formation can make recent stats less relevant overnight.

How BetSignals processes player stats
BetSignals collects player-level data from the last ten appearances for each player before an upcoming fixture. It applies SignalRates: Bayesian shrinkage towards the league average plus an opposition adjustment, to produce a more context-aware probability for each stat.
The result is r1, r2, r3 probabilities for each stat: the likelihood of a player recording at least 1, 2, or 3 of that stat in the match. These are directly comparable to bookmaker odds for bet builder legs.

What player stats cannot tell you
- Whether a player will start or what their expected minutes are
- In-match tactical changes
- Form factors beyond the quantifiable (confidence, fitness, personal circumstances)
- The quality of teammates around them in the specific match
Stats are the foundation. Context on top of the foundation is still your job.
