It's easy to track everything and learn nothing. A stat sheet full of points, rebounds, and assists from last Saturday's game tells you what happened — it doesn't tell a 14-year-old whether the extra hour in the gym this week actually did anything. The stats worth tracking are the ones that show a trend over weeks and months, not a single box score.
Game stats vs. development stats — pick the right one for the question
Game stats (points, rebounds, assists, turnovers) answer "how did we do Saturday." Development stats (shooting percentage by zone, free throw percentage, vertical jump, sprint times) answer "is this player actually getting better." Most programs only track the first kind, which is exactly why summer work is so hard to stick to — there's no number proving it's working.
The stats actually worth tracking
- Free throw percentage, logged weekly. The single easiest stat to track consistently, and one of the clearest improvement signals there is — no subjectivity, no defense to account for, just makes over attempts.
- Shooting percentage by zone (left wing, right wing, top of key, paint), not just overall field goal percentage. A player shooting 45% overall might be hiding a 20% night from one specific spot — the zone breakdown is what actually tells them what to work on.
- Vertical jump, sprint time, or another physical benchmark, tested on a fixed schedule (e.g. first week of the month). These move slowly, which is exactly why tracking them matters — a player who only checks in once a season has no idea the work is paying off.
- Turnovers per 10 minutes played, not turnovers per game — controls for playing time so you're not comparing your starting point guard's turnovers to your 8th man's.
- Assist-to-turnover ratio for ball handlers specifically — a better decision-making signal than raw assist totals, which reward playing with good finishers more than they reward good decisions.
Stats that look useful but usually aren't
- Points per game, on its own. Heavily dependent on role, minutes, and how many shots a player is given — two very different players can have the same PPG for completely different reasons. Pair it with shooting percentage and minutes played or don't bother.
- Total rebounds without an opportunity context. A big who plays 30 minutes will out-rebound a bench big who plays 10, regardless of who's actually better at it. Rebounds per minute is the more honest number.
- Anything tracked once and never again. A single vertical jump test in October with no follow-up isn't a stat, it's a trivia fact. The value is entirely in the second and third measurement showing a trend.
How often to actually log something
Game stats: every game, obviously. Development stats: weekly is usually the sweet spot — frequent enough to catch a trend within a month, infrequent enough that it doesn't feel like a chore. Physical benchmarks (vertical, sprint, broad jump) work fine monthly; testing them weekly mostly just measures day-to-day variance, not real progress.
Why this matters more than it seems
A player who can see "free throw percentage: 58% → 64% → 71%" over ten weeks has actual proof the offseason work is paying off — which is usually the difference between someone who keeps showing up to the gym in July and someone who quietly stops. It's also a completely different conversation with a parent: "here's what we tracked and here's the improvement" lands very differently than "he worked hard this summer."
This is exactly what HoopVault's stats feature is built for — pick any metric that matters for a player (not a fixed list), log entries over time, and see the actual trend line instead of a single disconnected number.
