The San Francisco 49ers’ undefeated 5-0 start and head-to-head victories over both the Rams and Seahawks have established them as the clear frontrunner for the NFC West title, reflected in the 69.5% implied probability. Their +61 point differential underscores consistent offensive efficiency and defensive dominance through the first five weeks. The Los Angeles Rams (15.5%) sit at 2-3 after a narrow overtime loss to Buffalo, while the Seattle Seahawks (12.5%) are 3-3 following their defeat in San Francisco. The Arizona Cardinals (0.9%) remain mired at 1-4. Multiple 49ers injury concerns, including Nick Bosa’s calf and Deebo Samuel’s hamstring, introduce some uncertainty for upcoming matchups, yet their current form and remaining schedule continue to anchor market sentiment.
