What could flip it
- Without Tyrese Haliburton (IND), with his minutes at replacement level, the model would give BOS 63.4%.BOS 63%
- Without Payton Pritchard (BOS), with his minutes at replacement level, the model would give BOS 53.6%.BOS 54%
- What the model does not look at and this number does not capture: rest and travel, the day's injury report, the starting five and recent form.
Uncertainty
- The model gives a number, not a band: its reliability is measured by comparing forecasts with results, not by drawing a margin.
- Over 10,749 games in 2017-2025 it did better than home court alone (Brier error 0.227 versus 0.247; 0 would be perfect).
- Rosters are not settled: the forecast is recomputed daily with that day's roster.
- It does not know injuries, rest, travel or the starting five: any of them can move this game without the number changing.

How it is measured and limits
Model
SportiveWorld's game model, frozen before the season: it reads each roster's projected strength and home-court advantage. It does not read the day's injury report.
Data is up to date.
Sample · No settled games yet to measure it against.
Injuries · The model does not read the day's injury report: the rosters it uses are the season projections.
- · Rosters are not settled yet: the number can move until the season starts.
