This Week 9 NFL betting guide pulls together model simulations, expert angles and prop plays across the Sunday and primetime slates. The headline item is a five-team parlay built by a model that runs every game 10,000 times and has returned more than $5,000 for $100 bettors on top-rated picks since launch. That parlay pays close to 30-1.
Model's top spread play: Commanders cover vs. Rams
The model’s favorite side entering Week 9 is Washington catching 4.5 points against Los Angeles, with a total of 47.5. It projects the Commanders to cover 59% of the time. The model has been on a 60-51 run on top-rated picks since 2024 and has picks for every game on the board.
Five-team parlay leans on Seahawks-Cardinals Over
One leg of the near-30-1 parlay is Over 44.5 in Seahawks vs. Cardinals. The simulation forecasts 52 combined points, giving the Over a 67% hit rate in its view. The remaining four legs are available through the full parlay card.
Expert angle: Giants (-3) vs. Eagles
Larry Hartstein, who is 11-4 (+646) on his last 15 NFL ATS picks, is backing New York to cover at home against Philadelphia on Sunday at 1 p.m. ET. His reasoning centers on Philadelphia’s recent efficiency: over the past three games, the Eagles have averaged 4.2 yards per play on offense while allowing 5.9, which Hartstein calls the worst combination in the league. He also notes that Nick Sirianni has said no changes are coming to the offensive staff or at quarterback.
On the other side, the Giants return from their bye. Cam Skattebo (hamstring) may not play, but Hartstein views Devin Singletary as a capable replacement.
DFS optimizer: Kyren Williams, Chris Olave among top plays
For the main Sunday slate on DraftKings and FanDuel, the DFS Optimizer — which combines the Advanced-Data Projection Model with input from millionaire DFS player Mike McClure — lists Rams running back Kyren Williams and Saints wide receiver Chris Olave among its top picks. The tool simulates every game 10,000 times to help build lineups.
Fantasy football: Malik Willis projected as top-12 QB
The same simulation engine has produced Week 9 fantasy rankings that can guide start-sit calls. One notable projection: Dolphins quarterback Malik Willis is forecast as a top-12 fantasy quarterback this week. Full positional rankings are available for every spot.
Sunday Night Football prop: Mayfield under 18.5 completions
Bears vs. Buccaneers features two Heisman-winning, former Oklahoma Sooners and No. 1 overall picks in Caleb Williams and Baker Mayfield. Chicago is coming off a Monday night win over the reigning Super Bowl champion Seahawks, while Tampa Bay handled Atlanta on Sunday without completing a pass. The AI Machine Learning Model has made a five-star prop play on Mayfield under 18.5 completions (-102).
Monday Night Football: Bills (-3) at Vikings, lean Under
Buffalo’s top-ranked scoring offense visits Minnesota’s top-ranked scoring defense, with both teams at 6-1. The concerns sit on the other side of the ball: the Bills rank 24th in points allowed, while the Vikings are 27th in scoring.
R.J. White, who is 39-17-3 (+22.8 units) on his last 59 ATS picks in Vikings games, is backing Buffalo to cover and leaning Under 44.5. He points out that Buffalo’s biggest game of the season turned into a clunker after Lamar Jackson was hurt on his first snap, making the defensive performance hard to read. Meanwhile, Minnesota’s offense has had two uninspiring showings against questionable defenses and has managed just six offensive touchdowns since Week 2. White notes that Buffalo has scored at least 24 in every game, at least 26 when not turning the ball over five times, and at least 33 in five of seven games. A good Lions offense reached 19 against Minnesota, and White expects the Bills to reach 20 and cover.
Rest-disadvantage trends worth noting
Denver visits Carolina on Sunday, and Sean Payton’s team has been strong when working with less rest than its opponent. Since 2024, the Broncos are a league-best 7-2 against the spread in those spots and 8-1 straight up.
Cleveland faces a New Orleans team coming off a bye. The Saints are on an 0-8 ATS run following byes, a trend that could push bettors toward the Browns in parlays and player props.
