Method

Read against .

  • Expected is an offense and a defense a team, fit over every game of its season between two teams in the table with the game being read left out, plus 0.7% in 2025, plus 1.4% in 2026 for the home team (the edge the fit finds once strength is in), nothing at a neutral site.
  • Each expected number is then fit to the season’s games: a game bears out about 56% in 2025, 40% in 2026 of the difference the model predicts.
  • The two sides are the games before and after one date, so the shuffle moves any game between them.
  • Stony Brook, Portland State have no other game in the table, so those games have no expected number and sit out the second figure.
  • Who played is read from the schools’ box scores’ participation lists for 15 of these 22 games; in the other 7 a player is counted as in them when the box score has a stat for him.
  • 3 games in 2024 are neither with Christian Washington nor since Christian Washington’s last game: Christian Washington had no game for the team that season, and sit out.
