Injury adjustment
Report pulled 2026-10-27 13:20 UTCRatings describe a team over a whole season. Who is actually available on Sunday is a separate question, so the injury adjustment is applied last, after home field and rest. Each listed player costs a share of a point of spread based on his position, whether he starts, and how likely he is to play.

Statuses come straight from the league injury report: out and injured reserve count in full, doubtful three quarters, questionable roughly a third, probable a tenth. Starters are identified from the depth chart; anyone the model cannot place is treated as a backup.
Move the factors yourself
Every term feeds one number: the adjusted Elo difference. Drag any of them and watch the spread and confidence follow.
Drag to see how much a stronger or weaker host changes the call.
The two ratings only matter through their difference.
The tuned value is a flat 25 points for every host.
5 Elo per extra day of rest, capped at 25 either way.

Probability curve
The logistic curve from −600 to +600 Elo, home perspective. The dot is your current setting; the faint vertical line is where the model itself sits. Notice the curve is flattest at the extremes — near a coin flip, every point of Elo moves the number most.
Where the ratings came from
Each rating is the end state of a full 2025 season of Elo updates, regressed toward the league mean for the new season.

Matchup factors
Everything beyond the two base ratings that moved this specific number.
Home field
+25.0 pts
worth 2.6 points of win probability
MIN hosts at U.S. Bank Stadium. Every host gets the same flat 25 points — the model does not rate crowds individually.
Rest
+25.0 pts
worth 2.6 points of win probability
5 Elo points per extra day of rest, capped at 25 either way.
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.

What the model does not know
- · How an injury actually plays out — the adjustment above prices availability, not how well a replacement performs.
- · Coaching and roster turnover between seasons.
- · Weather, travel distance and short-week fatigue beyond raw rest days.
- · Anything a betting market has priced in since the season ended.
