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 shuffle keeps the season’s shape: the games are cut in two where one date leaves the least variance, each game is read against its stretch, and the sides are shuffled only inside each stretch.
  • New Hampshire, Stony Brook, Sacramento State, UMass 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 20 of these 21 games; in the other game a player is counted as in it when the box score has a stat for him.
  • 4 games in 2024 are neither with Jalen Bonds nor without Jalen Bonds: Jalen Bonds had no game for the team that season, and sit out.
