How the number is built
Elo inputs in rating points (higher favors that team; 25–28 Elo is about a point of spread in football and basketball), then how the pieces combine.
| Factor | POR | SA | Why |
|---|---|---|---|

| Home field | — | +36 | Worth 36 Elo in the NBA |
| Lineups | +55 | +67 | POR: Stronger than its recent lineups · SA: Stronger than its recent lineups (from the box score) |
| Elo ratings | SA +249 Elo | SA 80.7% | |

| Pre-line forecast | SA 78.9% | 10% Elo, 90% market-implied (log-odds blend) | |
| Forecast | SA 83.2% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
