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 0.6 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 61% 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.
- Utah Tech 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 4 of these 8 games; in the other 4 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 Journee Tonga nor without Journee Tonga: Journee Tonga had no game for the team those seasons, and sit out.
