The shot was not the story, the possession was
Jan 19, 2026 1:40 pm
Coach Ermay keeps seeing the same problem in film.
Teams talk about makes and misses.
They skip the part that decides the shot.
Advantage Chains grades the possession before the shot.
It introduces the Advantage Chain Index (ACI), a simple 0–3 call that gives coaches and players one shared language in real time:
0 Neutral
1 Advantage
2 Tilt
3 Cash-Out
A weekend example.
One current Ubuntu Basketball client, Leon, U16 regional in Germany (name changed), used ACI language in his last game.
Before warm-up, he and his coach agreed on one rule.
If it is Advantage, it is 0.5 seconds, shoot, drive, or move it.
If it is Tilt, do not force it, flow to the next action.
Result.
Leon finished with 17 points in a crucial win.
Not because he got “hot.”
Because he stopped taking Tilt shots, and started cashing out Advantage touches.
That is what this book is built for.
Inside Advantage Chains, Coach Ermay shows how to tag film fast, track chain length and time-to-action, and turn those tags into:
1 one decision rule for the week
2 one small-sided constraint you can run in practice
3 one measurement plan for the next game
Another quick one.
A second Ubuntu Basketball client, Marek (name changed), used ACI tags to clean up late-clock habits.
He tracked just one stat, how many possessions ended in Tilt pull-ups.
Next practice, he trained one constraint, no Tilt pull-ups unless the clock is under 3.
Next game, his shot quality went up, and so did his confidence.
Pre-launch offer.
Advantage Chains is €5 right now.
