Team notes provide historical context. Controls use authored rates, coefficients and a fixed 58% miss assumption, not calibrated NBA predictions. The 100 dots show simplified categories; residual dots are unclassified. Total rebounds include both offensive and defensive rebounds. No player-specific points-saving effect is established.
A turnover or rebound can end a chance; totals do not isolate a player’s impact
Does moving a slider tell you what Portland would actually concede?
No. This page adds chosen coefficients to a historical reference value. Scheme buttons select preset assumptions, and the court shows an authored schematic. Neither player attribution nor an observed shot-quality model is estimated. Treat the controls as a lesson in assumptions, not a scouting forecast.
The rating formula and dot categories are separate calculations. The dots omit free throws, possession continuation, shot values and many other outcomes. A remaining dot cannot be assumed to be a scoring possession. Historical season totals are not the per-possession slider percentages.
Try a worked example
At the default 17.2% turnover and 78.4% rebound assumptions, the grid rounds turnovers to 17. It assumes round((100 − 17) × 0.58) = 48 misses, then round(48 × 0.784) = 38 secured rebounds. The 55 categorized stops leave 45 unclassified dots. The separate rating formula stays 109.3. Increasing turnovers by one percentage point lowers that formula by 1.2 before clamping; this coefficient is chosen, not measured.
Name the statistic and its denominator
NBA defines team defensive rating as points allowed per 100 possessions. A rate needs its denominator and sample window. NBA Stats: glossary
The official 2025–26 notes support the historical totals and post-All-Star rating; their windows differ. Trail Blazers: 2025–26 game notes
The Jr. NBA box-score guide separates total, offensive and defensive rebounds. A total rebound count must not be relabeled defensive boards. A forced-turnover label also needs a definition; it is not interchangeable with a player committing turnovers. Check the source’s statistic definition before comparing players.

Read the model’s own rules
The formula starts at 109.3, subtracts 1.2 per percentage-point turnover change and 0.65 per rebound-point change, then subtracts 0.8 per funnel-index step above 2. It clamps the result to 98.5–122.0. These weights encode the author’s assumptions. Funnel index changes this score but not the dots.
Blitz, drop and switch buttons change rate presets and court positions. Manual slider edits do not change the scheme name, so exports contain both the selected schematic and actual rates. Reset restores drop with the original rates and funnel index. JSON and PNG exports retain historical context while labeling the scenario unvalidated.
