Match data can reveal patterns, but every metric has limitations. Event definitions differ by provider, tracking coverage can be incomplete, and a small sample can make random variation look meaningful. A statistic may also reflect game state: a team that falls behind can accumulate shots while its opponent defends a lead.
State the source, period and definition, and compare like with like. Use several indicators and describe alternative explanations. Data supports analysis; it does not remove uncertainty or guarantee the next result.
