The spot: Big disagreement
Elo and the market are 10 or more points apart. Over 24 seasons (943 games) Elo's side won 50% while Elo claimed 63% and the market 49%. The market was right almost every time. Take the market's number, or split the difference at most. This is where Elo is overconfident.
Los Angeles Chargers over the 49ers: Elo 45%, market 57%. Big disagreement: trust the market number. Herbert is worth 18 Elo.
Details
- Rest: LAC 4 days, SF 4 days.
- Quarterback adjustment: LAC +18 (Justin Herbert), SF -1 (Brock Purdy). How that works.
- Weather. Indoors (dome), so no weather adjustment.
