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 1.9 in 2025, plus 0.6 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 49% in 2025, 32% 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.
- Who played is read from the snap counts, which name every player who took a snap on offense, defense or special teams.
- 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.
- 9 games in 2024 are neither with Mac Jones nor without Mac Jones: Mac Jones had no game for the team that season, and sit out.
