Method
- 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 3.1 in 2025, plus 3.7 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 87% in 2025, 79% 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.
- Portland State, Utah Tech 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 13 of these 22 games; in the other 9 a player is counted as in them when the box score has a stat for him.
- 3 games in 2024 are neither with Preston Rex nor without Preston Rex: Preston Rex had no game for the team that season, and sit out.
