Method

Read against .

  • Expected is an offense and a defense a team, fit over every 2026 game between two teams in the table with the game being read left out, plus 1.4% 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 40% of the difference the model predicts.
  • Who played is read from the schools’ box scores’ participation lists for 6 of these 8 games; in the other 2 a player is counted as in them when the box score has a stat for him.
  • 17 games in 2024 and 2025 are neither with Chase Sowell nor since Chase Sowell’s last game: Chase Sowell had no game for the team those seasons, and sit out.
