Why the 49ers can cover

Riding a five-game win streak, San Francisco leads the NFL in points per game, points per drive and 3rd-down offense during this run, and each of the five victories have come by double-digits. The offense has been unstoppable over the last two games in particular, as the Niners are just the fifth team in the last 75 years to go back-to-back outings without punting the ball. Though he doesn't qualify for statistical leaderboards due to time missed, Brock Purdy leads the NFL in QBR and is among the top five in touchdown percentage, completion percentage and passer rating. Additionally, the 49ers are 4-0 both straight up and ATS on primetime in 2025. See which team to back at SportsLine.
