Oddsmakers are typically hesitant to make significant mid-season adjustments to teams with high ceilings, opting for a conservative approach to futures betting markets on the Super Bowl, conferences and divisions.
The San Francisco 49ers closed out October with three straight losses, yet oddsmakers kept them among the top tier of Super Bowl favorites, in line with the Philadelphia Eagles and Kansas City Chiefs. At most books, the 49ers have had single-digit Super Bowl odds throughout the season.
Sportsbooks took a more aggressive approach to the Buffalo Bills, who began the season with around the same odds as the 49ers, Eagles and Chiefs, but struggled into December with a 5-5 record.
