The NFL's Week 9 schedule features several high-profile matchups with significant betting implications. The Minnesota Vikings, the league's last unbeaten team, enter as 3-point home underdogs against the AFC East-leading Buffalo Bills on Monday Night Football. Meanwhile, the 6-1 San Francisco 49ers host the Las Vegas Raiders as 10-point favorites, and the Arizona Cardinals visit the Seattle Seahawks in a divisional clash where the line has shifted after quarterback Sam Darnold was ruled out with a quad injury.
Gardner Minshew will start for Arizona after the Cardinals rallied from a 14-point deficit to defeat the Dallas Cowboys 33-30 in overtime in Week 8. Running back Tyler Allgeier has emerged as a key contributor, logging 72 carries for 323 yards and two touchdowns this season, including a 147-yard, one-touchdown performance against Dallas. Tight end Trey McBride leads the team with 66 receptions for 544 yards and five touchdowns. For Seattle, Drew Lock replaces Darnold and previously guided the offense to 31 points in a start this season, with wide receiver Jaxon Smith-Njigba recording 64 catches for 985 yards and nine touchdowns.
Other notable Week 9 games include the Los Angeles Rams vs. Washington Commanders (+4.5), Houston Texans vs. Los Angeles Chargers (+5.5), and Tampa Bay Buccaneers vs. Chicago Bears (-6) on Sunday Night Football. The Chargers have dropped 10 consecutive games dating back to last season.
A computer model that simulates every NFL game 10,000 times has produced a five-leg parlay for Week 9 with a potential payout near +3000. The model, which has returned more than $5,000 for $100 players on top-rated picks since its inception, entered the week on a 60-51 run on top-rated selections dating back to 2024.
The model's top pick is the Over 39.5 points in the Cardinals-Seahawks matchup, a side that hits in 76% of simulations. The Over has cashed in six of Arizona's last 10 games and three of Seattle's last five. Seattle ranks 11th in scoring at 24.0 points per game, while Arizona averages 21.9 points per game, ranking 21st.
The model also identifies four additional games where it believes the betting line is significantly off, including multiple spread picks that hit well over 50% of the time in simulations. The complete set of Week 9 best bets and the parlay construction are available through the model's subscription service.
