Which team gets the ball?
Which team is more likely to control the opening possession?
FIRST BASKET LAB · HOW IT WORKS
We use earlier basketball games to estimate opening possession, the first player to score, and that player's scoring method. These are experimental probabilities, not guarantees or betting recommendations.
Which team is more likely to control the opening possession?
A ranking of the ten confirmed starters. Made free throws count.
A conditional forecast: if our selected player scores first, which method is most likely?
Our main target is the player credited with the game's first points. A made free throw counts; a missed free throw does not. A made two-pointer or three-pointer also counts. If a free throw comes before the first field goal, the two categories can have different winners. Our definitions do not determine any sportsbook's settlement rules.
Our statistical models consider historical player performance, confirmed starters, team matchups and shooting tendencies. They use earlier games, not the game being predicted or future outcomes. LLMs assist development and research; they do not directly generate the displayed probabilities.
Forecasts can be unavailable when lineups or supporting data are incomplete. Missing information is not presented as a confident prediction.
The first card estimates which team is more likely to gain opening control, informed by previous opening possessions and the expected matchup. Getting the ball first does not guarantee taking the first shot or scoring first. We grade this forecast only when normal opening control can be verified.
The second card highlights the highest estimated first-points probability among the ten confirmed starters. The ranking considers player scoring history and team context. Those ten probabilities total 100%; a leading player is still more likely to miss than score first when their probability is below 50%. Tied leaders are not forced into a pick.
The third card estimates the scoring method if our selected player scores first, informed by their earlier scoring and shooting history. Methods include free throws, three-pointers and different types of two-point baskets. Its percentage is conditional: it is not the chance of getting both the player and method right.
“Accuracy to date” means correct decisive picks divided by graded decisive picks. Today's games are excluded using Eastern Time. Ties and unresolved evidence are excluded and reported separately, so each card can have a different sample size.
Method accuracy counts only games where our selected player actually scores first and the method is known. A wrong-player result is a combined player-and-method miss, not a conditional-method trial. Non-starter first scorers count as player-pick misses but are excluded from probability-quality scores requiring the ten-player choice set.
Our research also checks how well the probabilities match observed outcomes, not just how often the top pick wins. Accuracy alone does not establish profitability.
Historical replays are reconstructed after games, using earlier history. They may include corrected data and lineups whose pre-tip availability is unknown. Saving a replay for faster loading does not make it a pregame prediction.
Saved pregame forecasts are recorded before tip-off and remain fixed while results are graded separately. We distinguish these sources in our reports. Historical research is not proof of future performance.
Lineup changes, limited history, data errors and unpredictable play all matter. This is an independent research and entertainment project, not an NBA-endorsed service. No outcome or financial return is guaranteed.
