LOS ANGELES — Right when the Los Angeles Rams’ offense has dropped into a disconcerting slump, their defense has held three straight opponents under 10 points for the first time in decades.

The Rams (10-6) are in the playoffs and riding a five-game winning streak, but the way they’re doing it makes their postseason prospects quite unpredictable.

The methodology has been strange, but the results are not: After holding off Arizona 13-9 on Saturday night, Los Angeles has won nine of 11. The Rams then clinched their fourth division title and sixth playoff berth in coach Sean McVay’s eight seasons when Washington beat Atlanta, 30-24, in overtime on Sunday night.

“I’m proud of this group and the way they battled back,” Matthew Stafford said. “A lot of people doubted us, and a lot of people wrote us off at 1-4. To be able to sit here with our record what it is right now, I feel proud of this group.”

The Rams hadn’t held three straight opponents to single-digit scoring since 1975, but rookie coordinator Chris Shula’s defense has done it with a strong front and a little luck on the back end, including the last-minute interception by Ahkello Witherspoon on a pass that deflected off star Arizona tight end Trey McBride’s head at the goal line. Kyler Murray threw it before McBride was probably ready because Shula had called a zero blitz on first down at the Los Angeles 5.

“I want to make more plays to make sure they don’t have to do as much as they did (against Arizona), but I’m proud of them,” Stafford said of the Rams’ defense. “It’s awesome to watch where they were in training camp to where they are now. Shula is doing a hell of a job. We all knew he would. Those guys are playing hard for him.”

Next Steps

The Rams began Sunday preparing as if they’ll play the Seahawks (9-7) next Saturday, although the game could happen a day later. McVay won’t show his cards, but with the Rams having clinched, they seem likely to rest several regulars for the playoffs.

Offensive Struggles Persist Despite Winning Streak

The Rams have scored more than 21 points just once during their five-game winning streak, their longest since their Super Bowl championship season in 2021.

They’ve managed only three touchdowns in their last three games while scoring fewer than 20 points each time out, although that stretch includes games played in the rain (San Francisco) and in subfreezing temperatures (New York Jets).

Against the Cardinals in Inglewood’s ideal weather, the Rams’ offense still produced one TD, a season-worst 12 first downs and only 257 total yards — 139 fewer than Arizona. The running game struggled again, as it often does when all five starting offensive linemen aren’t healthy, while the entire roster aside from Puka Nacua combined for just seven receptions for 60 yards — a surprising number for a McVay offense.

“I don’t think there’s one thing I can point to,” McVay said Sunday. “I could go on and on about some of the things, starting with me, but then also about our execution in terms of getting connected in the run game, targeting the right way, making sure that the ball is going where it should go, and guys that I know are capable of playing the way that we’ve seen. If they do that, then I know that it’s not as far as sometimes it can feel like. But ultimately, we’ve got to do it.”

What’s Working

The young front four remains the strength of the defense. Jared Verse had a tremendous game on the edge against Murray and Arizona’s running game, while fellow rookie Braden Fiske and second-year pros Kobie Turner and Byron Young all recorded sacks.

What Needs Help

The Rams again failed to establish the running game despite never trailing Arizona. Kyren Williams got his second-fewest carries of the season (13, with just five in the second half), while rookie Blake Corum was barely involved. Los Angeles’ 3.9 yards per rush is the second-lowest mark in the NFL even though Williams began Sunday third in the league with 1,299 yards.

Stock Up

Witherspoon not only made the game-saving interception, but the eight-year veteran who went unsigned until September also has seized the starting cornerback job from Cobie Durant, who didn’t play on defense against the Cards despite being healthy again. McVay said Witherspoon’s play during Durant’s brief injury absence resulted in the change.

Stock Down

Cooper Kupp had one catch against Arizona, and he has just 12 receptions in the past five games, matching the least productive five-game stretch of his eight-year career. Stafford has said the Rams need to get their Super Bowl 56 MVP more involved, and Kupp says he’s healthy — yet it isn’t happening.

Injuries

McVay believes the Rams stayed healthy outside of a stinger for rookie safety Kam Kinchens, but they felt the absence of RT Rob Havenstein, who injured his shoulder last week during an unpadded practice. Backup Joe Noteboom committed three holding penalties and got beaten repeatedly.

Key Number

4 — Stafford’s consecutive games without taking a sack. That’s the longest streak of his 16-year career, yet he has only one 200-yard passing game in that stretch.
