Buffalo is a hefty favorite at home for this contest. After beating the Texans on the road and the Lions at home, momentum is on their side. That’s more true after seeing the Chargers lose to two of the teams expected to be among the worst in the league this season in the Arizona Cardinals and the Raiders.

Los Angeles, even when things were going well for them the last few seasons, struggled to put up numbers in the opening month of the year. The Chargers have stayed under the number in five straight games overall.

In addition, they’ve turned in four straight unders in games against teams with winning records. The Chargers also recorded four straight unders after losing a game straight up. After seeing them score just 14 points in each of their first two games, it’s tough to get excited about them offensively.

In Justin Herbertl’s career as a starting quarterback, he’s been an underdog by more than a field goal 16 times. In those games, the Chargers recorded just four victories. This is a Chargers squad that is playing their third-string left guard in this one with Trey Pipkins and Kayode Awosika out.

In addition, they have a rookie starting at center and a guy in Cole Strange at right guard who was a first round pick in 2022 yet is on his third team in as many years. You have to think that Deone Walker and a Buffalo defensive line that has been effective the first two weeks of the year is licking their chops.

Buffalo showed that they can do damage on offense regardless of who is on the other side of the field. Houston was the top scoring defense in the league last season and the Bills hung 36 on them on the road. Meanwhile, Buffalo buried Detroit early, leading 27-7 in the second quarter, and ended up putting 41 points on the board in that win. The Bills have an extra three days of rest and they were at home. This is a 10 am PT start for the Chargers, so their body clocks may be a bit of whack here as well.

Josh Allen set the world on fire in the first two weeks of the year. He has nine touchdowns and no turnovers in those two games. That makes him just the third quarterback to total nine scores without a turnover in the first two games of the season. The other two were Peyton Manning and Patrick Mahomes. Both men won the MVP in their season accomplishing that feat.

Chargers vs. Bills Prediction: Buffalo -7 (-115)

While Buffalo’s defense has surrendered 31 points in both games this season, a closer look is needed. The Bills have seven sacks on the ledger and the Lions scored 21 second half points last week yet never got closer than 10. Buffalo has 77 points on the board in the first two weeks, making them the highest-scoring team in the league.

Meanwhile, we saw the Chargers muster just 14 points against both the Cardinals and the Raiders. Los Angeles turned the ball over five times in their first two games this season. The interior of the Chargers’ offensive line is going to have their hands full trying to contain Deone Walker, with or without Ed Oliver lined up next to him. Injuries are too much for the Bolts to handle and Allen’s torrid start to the year continues as he racks up big numbers again here.

As of 1 am ET Sunday morning, 97% of moneyline bets were on the Bills. In addition, 75% of the spread bets were on Buffalo -7 while 72% of bets were on the under for this contest.
