Chargers @ Bills Week 3 Preview: Buffalo Looks to Stay Perfect Against Reeling Los Angeles

The Buffalo Bills are 2-0 and looking every bit like a Super Bowl contender. The Los Angeles Chargers are 0-2 and searching for answers. The betting market has taken notice, moving this line from Buffalo -6.5 to -7.5. Our model predicts a 34-20 Bills victory, and the numbers back up that confidence.

Buffalo Bills: Offensive Firepower, Defensive Concerns

Buffalo's offense is operating at a historic pace. They're averaging 38.5 points per game and 435.5 total yards, with a balanced attack (291.0 passing, 144.5 rushing). Josh Allen is playing at an MVP level, throwing for 582 yards, 5 touchdowns, and zero interceptions with a 125.8 passer rating. He's also a threat on the ground, rushing for 92 yards and 4 scores.

The skill position talent is deep. Tight end Dalton Kincaid is a matchup nightmare, averaging 112.5 yards per game on 6 receptions. Running back James Cook is averaging 96.0 rushing yards per game at 5.6 yards per carry. The addition of DJ Moore (50.0 ypg, 20.0 ypr) gives Allen another vertical threat. This offense doesn't turn the ball over — zero giveaways per game — and that's a major reason they're scoring at will.

The defense, however, is a different story. Buffalo is allowing 31.0 points per game, one of the highest marks in the league. They're one of only three teams ever to start 2-0 while allowing 30+ points per game, per recent reports. They've generated 3.5 sacks per game and 1.0 takeaway, but they've been vulnerable through the air and on the ground. The saving grace has been a +1.0 turnover differential per game, which has helped offset some of the defensive lapses. Still, if the Chargers can protect the ball, they might find some success moving the ball. But that's a big if.

Los Angeles Chargers: Struggling Offense, Turnover Issues

The Chargers' offense has been a mess. They're averaging just 14.0 points per game and 304.5 total yards. Justin Herbert has been uncharacteristically sloppy, completing 59.3% of his passes with 2 touchdowns and 3 interceptions for a 71.6 rating. He's been sacked 3.0 times per game, and the offense is turning the ball over 2.5 times per game. That's a recipe for disaster against a Bills team that thrives on short fields.

The running game has been mediocre, averaging 104.0 yards per game. Omarion Hampton leads the way with 68.5 yards per game but at just 3.9 yards per carry. The passing game lacks explosiveness — Ladd McConkey (58.5 ypg) and David Njoku (33.5 ypg) are reliable but not game-breakers. Quentin Johnston's struggles have been well-documented, and the Chargers' new offense under coordinator Mike McDaniel hasn't clicked yet. And with the NFL's toughest schedule from Week 3 on, this game is a critical early test.

Defensively, LA is allowing 26.0 points per game. They generate only 1.5 sacks per game and 0.5 interceptions, and their turnover differential is a league-worst -2.0 per game. That's a dangerous combination against a quarterback like Allen who protects the ball.

Key Matchups

Josh Allen vs. Chargers Defense: Allen is playing at an elite level, and the Chargers have managed just 0.5 interceptions per game. If Derwin James (fractured pinky) is limited or out, the middle of the field will be open for Kincaid. Allen's mobility will also test a Chargers front that hasn't generated consistent pressure.

Justin Herbert vs. Bills Pass Rush: Buffalo gets after the quarterback with 3.5 sacks per game. Herbert has already been sacked six times in two games. If the Bills can pressure him, he's shown a propensity to force throws — his 3 interceptions are evidence. The Chargers' offensive line must hold up, but that's been a problem.

Turnover Battle: Buffalo is +1.0 per game, while Los Angeles is -2.0. This is the single biggest mismatch in the game. The Bills' offense capitalizes on short fields, and the Chargers' defense hasn't been able to create takeaways.

Model's Pick

Our model predicts a 34-20 Buffalo win, which covers the -7.5 spread with room to spare. The model gives Buffalo a 73.88% confidence in both the ATS and moneyline picks. The predicted total of 54 points is slightly above the 50.5 over/under, suggesting a lean to the over. However, the Chargers' offensive ineptitude could keep the total under if they can't sustain drives. The model's confidence in the spread is high because of the massive disparity in offensive efficiency and turnover margin.

Betting Angles

The line opened at Buffalo -6.5 and has moved to -7.5, indicating sharp money on the Bills. The moneyline sits at Buffalo -375 (implied 78.9% win probability) and Los Angeles +300. Our model gives Buffalo a 73.88% chance to win outright, which is slightly below the implied probability, suggesting marginal value on the Chargers' moneyline if you believe in a backdoor cover. But the ATS pick is the stronger play.

The over/under has stayed steady at 50.5. Buffalo's games have averaged 69.5 combined points, while the Chargers' games have averaged 40.0. The truth is somewhere in between. The Bills' defense allowing 31.0 points per game is a concern, but the Chargers may not be able to exploit it. If you're looking for a total play, the over is tempting given Buffalo's pace (58.2 plays per game) and the Chargers' defensive issues, but the Chargers' 14.0 PPG is a major anchor.

Situational Factors

This is a conference game, not a division game, so there's no extra rivalry angle. Both teams are on normal rest. The weather in Orchard Park is expected to be 66°F with 7 mph wind — ideal conditions, no factor. The Chargers are making their first trip to Orchard Park since 2020, and the Bills have won the last two meetings in this series. The all-time series is tied 2-2 in the last four, but Buffalo has the recent edge.

Injuries: The biggest name to watch is Derwin James (fractured pinky). If he can't go or is limited, it's a significant blow to a Chargers secondary that already struggles to create turnovers. No other injuries are listed, but keep an eye on Quentin Johnston's role — his struggles have been a talking point.

Final Verdict

Pick: Buffalo Bills -7.5 (confidence: 73.88%)

The numbers don't lie. Buffalo's offense is a machine, and the Chargers can't keep up. Los Angeles turns the ball over too much (2.5 per game), can't stop the run or pass effectively, and Justin Herbert is having the worst stretch of his career. The Bills' defense is vulnerable, but they won't need to be perfect with Allen at the helm. Lay the points with confidence.

Prediction: Buffalo 34, Los Angeles 20
