NFL Week 1 matchups on Sept. 9 and Sept. 10
- Seahawks to win vs. Patriots (62%)
- Rams to win vs. 49ers (64%)
Patriots vs. Seahawks
New England and Seattle open the season on Wednesday in a Super Bowl rematch, which is rare for the opening game of the new campaign. The Patriots upgraded their receiver group in the offseason, trading for A.J. Brown and signing Romeo Doubs in free agency. The Seahawks let Super Bowl MVP Kenneth Walker depart in free agency, but they're hopeful rookie running back Jadarian Price can shoulder a heavy workload at the start of the new season. The Seahawks are trading at 62% to win on Underdog, while the Patriots are at 38%. The SportsLine model has Seattle winning on Wednesday in 74% of simulations.

49ers vs. Rams
This game will be played in Australia at the Melbourne Cricket Ground as the NFL continues to expand its overseas reach. The 49ers are hoping they can stay healthy for this campaign, though there are already some injury concerns regarding George Kittle, Christian McCaffrey and Mike Evans. The Rams assembled a talented roster this offseason by trading for Trent McDuffie and Myles Garrett before coaxing Aaron Donald to come out of retirement to chase a Super Bowl ring. Los Angeles is trading at 64% to win while San Francisco is 36% at Underdog. The Rams win in 64% of SportsLine simulations.
