49ers vs. Rams picks, predictions
Rams to win by more than 3.5 points ($0.51)
The Rams and 49ers both went 12-5 last season, resulting in Los Angeles' third straight double-digit win season while reaching 10 victories for the fifth time in the last six seasons. Matthew Stafford is 46-28 (.740 win percentage) over his five seasons as the Rams' quarterback. Los Angeles boosted its defense this offseason after trading for Myles Garrett, the reigning Defensive Player of the Year, after already having a top-10 scoring defense at 20.4 points per game allowed. The 49ers suffered injuries throughout last season and have had some setbacks during training camp as well, leading to the SportsLine Projection Model having the Rams winning by more than 3.5 points in 56% of simulations.
Los Angeles to win by 3.5 points or more is trading at $0.51 per contract at Kalshi. The Rams to win by fewer than 3.5 points or lose the game outright is trading at $0.50. Trade on the NFL at Polymarket with the Polymarket promo code CBSSPORTS to get a $50 trading bonus:
49ers vs. Rams: More than 48.5 total points scored
The Rams have one of the top playmaking trios returning this season with receivers Puka Nacua and Davante Adams and running back Kyren Williams. Meanwhile, the 49ers boosted their playmaking core by signing Mike Evans as a free agent and bringing Deebo Samuel back to San Francisco. Samuel spent last year in Washington after six seasons with the 49ers and has been used as a versatile playmaker by head coach Kyle Shanahan throughout his career. They add more options for quarterback Brock Purdy, as well as take some of the burden off Christian McCaffrey. The Rams had the No. 1 scoring offense in the NFL at 30.5 points per game last year, and in their two meetings last season, both resulted in more than 48.5 points scored, with an average of 58.5 ppg. The SportsLine Projection Model has more than 48.5 total points scored in 54% of simulations.
More than 48.5 total points is trading at $0.48 per share. Fewer than 48.5 total points is trading at $0.53. Trade on NFL Week 1 at Underdog with the Underdog promo code CBS to get a 50% deposit match up to $1,000 in bonus funds:
