Inside the Forecast

How the inputs are built

Why the model leans HOU

  • Home court+2.1 HOUWhat the model gives the home team on an average night.
  • Team strength+1.2 BOSElo HOU 1619, BOS 1621; season margin HOU +7.4, BOS +8.0.
  • Recent form+0.8 BOSLast 10 games, per 100 possessions: HOU scores 116.5 and allows 107.6; BOS scores 114.6 and allows 109.1.
  • Player availability+0.4 HOUBOS without Paul George (21 ppg).

Together: HOU by 1, a 53% chance. Smaller inputs make up the rest; the chart below has all of them.

Team-by-team notes from the box scores

HOU is 6–1, winning by 12 a game on average (scoring 121, allowing 108). Last season they were a +5 team, which still counts for 65% of their season margin. Their offense makes 26 free throws per 100 shots (league 21), which alone adds about 1.5 points per 100 possessions. Smaller factors: offensive rebounding +1.2. Their defense holds opponents to 51% eFG against a 55% league average, which alone adds about 5 points per 100 possessions. Smaller factors: forcing turnovers +2.7.

BOS is 5–1, winning by 10 a game on average (scoring 119, allowing 109). Last season they were a +7 team, which still counts for 70% of their season margin. Their offense shoots 53% eFG against a 55% league average, which alone costs about 1.6 points per 100 possessions. Smaller factors: ball security +1.1. Their defense holds opponents to 52% eFG against a 55% league average, which alone adds about 4 points per 100 possessions. Paul George (21 ppg) is out. They're on the second night of a back-to-back.

How the projected margin was built

Points of home margin. Right of zero favors HOU; left favors BOS.

Projected margin built from a baseline of +2.1 plus Team strength −1.2, Recent form −0.8, Player availability +0.4, No playoff context +0.2, Rest and schedule +0.1, giving +0.9 for HOU. -4-20+2+4 Model baseline +2.1 Team strength −1.2 Recent form −0.8 Player availability +0.4 No playoff context +0.2 Rest and schedule +0.1 Projected margin +0.9
Baseline +2.1 plus the bars equals the projected margin +0.9. The 53% win probability comes from a separate curve on that margin. This shows how the model used its inputs, not what will decide the game. How it's calculated
