Buffalo's First Loss Exposed the Exact Flaw the Rams Are Built to Attack

Three weeks ago the Buffalo Bills were the last unbeaten team standing in the AFC and looked like a machine. Then New England came into Highmark Stadium, hung 29 points on a Bills defense that had been coasting on reputation, and walked out with a 29-26 win. Now Buffalo takes its 3-1 record on the road for the first time since Week 1, into SoFi Stadium on Monday night, against a Rams offense that ranks third in the league in yards per game.

The timing is not kind.

The secondary is the story

The Bills are allowing 26.8 points per game and 390 yards per game, and the back end is where it shows. Christian Benford was ruled out for the Patriots game with a toe injury after leaving Week 3 early in a walking boot, and the dominoes fell toward Maxwell Hairston — who allowed a pair of one-on-one touchdowns to Romeo Doubs and then declined to speak with reporters about it. That's a young corner being asked to hold up against a passing game that stacks veteran receivers, and the tape says he isn't there yet.

New England's Drake Maye "regained his passing form" against that group, per Buffalo Rumblings' recap of the loss, and the Patriots entered the week having managed just 19 points on the season. That's the alarming part. This wasn't an elite offense finding a soft spot; it was a struggling one finding a soft spot.

Why Los Angeles is a terrible matchup for it

The Rams average 427.2 yards per game and 300.5 through the air. Davante Adams is at 97.5 receiving yards per game and 17.7 yards per catch. Puka Nacua works underneath. Sean McVay's offense runs 66.3 plays per game to Buffalo's 57.6, and it throws it 58.6 percent of the time on 41.3 attempts a game.

A leaky secondary against a team that wants to throw 41 times is a straightforward problem. And there's a wrinkle: Aaron Donald's return is trending in the right direction. McVay said the "hope" is that Donald plays Monday. Against a Buffalo run game that's been the offense's identity, his presence would change the math up front.

The hidden concern: the ball

Buffalo's offense isn't the issue — 31.8 points per game, tops in the NFL. Josh Allen has thrown for 1,039 yards with six touchdowns against three interceptions and a 100.1 rating, and he's added 118 rushing yards with seven scores on the ground. James Cook is averaging 5.9 yards per carry on 75 attempts.

But this team has put the ball on the ground eight times through four games, and the last three weeks have been measurably shakier than the season line suggests. Allen's rating over that stretch sits at 90.3 with an interception rate of 3.3 percent, up from 2.5 for the year. The Rams cough it up 1.8 times per game themselves, so this could turn into a giveaway contest — which is exactly the kind of game where the more efficient team usually wins.

One more thing to watch

Buffalo's 13-personnel usage has collapsed from 40.4 percent in Week 1 to 13.0 percent in Week 4, and there's been outside noise about getting Dalton Kincaid (67.5 yards per game) and the tight ends more involved. With DJ Moore nursing a shoulder injury he aggravated in Week 4, the Bills may need those tight ends regardless.

What's at stake

For Buffalo, this is a chance to prove the New England loss was a blip rather than the start of a pattern. The Bills opened as 2.5-point underdogs with the total at 54.5 — the first time all season they've been priced as the lesser side.

For Los Angeles, a loss drops the Rams to 2-3 and turns a slow start into a real problem.

Either way, the matchup that decides it is the same one that decided last week: can Buffalo's secondary hold up when it has to?
