Matchup factors
Everything beyond the two base ratings that moved this specific number.
Home field
+30.0 pts
worth 2.8 points of win probability
JAX hosts at EverBank Stadium. Every host gets the same flat 35 points — the model does not rate crowds individually.
Rest
+0.0 pts
Week 1: both teams come off the same offseason, so there is no rest edge to give.
Analyst override
+0.0 pts
No manual adjustment. The number here is pure model output.
2025 head to head
These teams did not meet in 2025. Past meetings carry no weight in the model anyway — they are already baked into each team's rating.
Strength of schedule
Who each team actually played in 2025, measured by their opponents' current ratings. This is context for reading the ratings — it is not an input to the prediction above, because beating good teams already raises a team's Elo more.
