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.
  • Southeast Missouri State has no other game in the table, so that game has no expected number and sits out the second figure.
  • Who played is read from the schools’ box scores’ participation lists for 7 of these 8 games; in the other game a player is counted as in it when the box score has a stat for him.
  • With him means he was the team’s quarterback that game, at least half of its pass attempts; a game he left early or came into late reads as without him.
  • 17 games in 2024 and 2025 are neither with Jaylen Raynor nor without Jaylen Raynor: Jaylen Raynor had no game for the team those seasons, and sit out.
