Method
- 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 4.1 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 59% of the difference the model predicts.
- Southern Illinois 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, which name every player who entered the game.
- 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 Katin Houser nor without Katin Houser: Katin Houser had no game for the team those seasons, and sit out.
