49ers 27, Rams 7 — Week 1: Ninety-Nine Yards the Other Way

Third quarter, three 46 left, San Francisco up 17 to seven in Melbourne. The Rams have run 11 plays and taken seven minutes and 17 seconds off the clock to get from their own 27 to the San Francisco one-yard line. Fourth and one. Matthew Stafford keeps it behind the right guard, Osa Odighizuwa is credited with the stop, the replay official looks at it and says short. San Francisco takes over at its own one. 11 plays and five minutes and 44 seconds later, Brock Purdy throws a 15-yard touchdown to Deebo Samuel, and with the extra point it is 24 to seven. That was the stretch that ended it. The Niners won 27 to seven at the Melbourne Cricket Ground, and the stretch that put it away was one yard the Rams could not get and 99 the Niners could.

Start with the defense, because a year ago it was the reason to worry about this team, and on Thursday it was the reason to stop. The Rams ran 28 pass plays and lost 11 expected points doing it. Expected points added is what a snap was worth given the down, the distance and the field position, and on defense a big negative number is the good direction — those are points the offense gave back by running the play at all. Only 10 of those 28 pass plays were successful, meaning they gained what the situation asked for. A hundred and 68 yards through the air, no touchdowns, one interception, and Los Angeles converted two third downs all night out of nine. Against the run the story is quieter but still good: a hundred and 23 yards on 28 rushing plays, one touchdown, and −4 expected points across the 28. And the takeaways came, which this defense managed 15 times in all of last season, tied for 20-fifth in the league. Renardo Green intercepted a deep ball for Puka Nacua on third and 10 in the second quarter at the San Francisco 14. Fred Warner forced a fumble from Tyler Higbee on a short catch in the fourth, and Keion White recovered it at the Los Angeles 43. Neither quarterback was sacked all night, on either side, so this was not a pass rush winning the game on sacks, on a night when the Rams ran nine snaps inside the San Francisco 20 and scored on one of them.

The passing offense had two halves. In the first half it netted slightly less than nothing across 25 pass plays and a hundred and 41 yards, the touchdown included, and it gave the ball away once: first and 10 at the Los Angeles 46, 12 minutes left in the second quarter, down seven to three, Purdy short right for George Kittle, intercepted by Quentin Lake at the 31. Then Green got the ball back at the 14, and the next drive went 86 yards in nine plays, the last of them second and six from the Los Angeles 39, Purdy deep middle to Demarcus Robinson for 39 yards and the lead. 12 points of win probability on one throw, the biggest single swing of the game. The second half was a different unit, and a smaller one: nine pass plays, 64 yards, two touchdowns, and +5 expected points on those nine alone. San Francisco threw 25 times before halftime and nine times after it, and ran 18 times after it. The night's line: 205 yards on 34 pass plays, three touchdowns, +5 expected points, 19 of the 34 successful.

The run game was the offense's best unit, and it was the one nobody expected. 30 rushing plays for a hundred and 74 yards, no touchdowns, and +6 and a half expected points — 17 of the 30 successful. A year ago this offense ranked 20-first in the league in expected points per rush attempt. On Thursday the two runs that opened the second half went 14 16 yards, both Christian McCaffrey, one behind the right guard and one behind the left, and the 99-yard drive got two of its first downs from Purdy scrambling: 18 yards on second and 10 with 10 seconds left in the third, then eight more on second and four early in the fourth.

Two things in the ledger that were not good, both about finishing. The opening drive ran 15 plays and 65 yards and seven minutes and 13 seconds, and ended with a 20-yard field goal after third and two from the Los Angeles two fell incomplete. And the last real possession, up 20, ran seven plays to the Los Angeles 34 and ended with a 52-yard field goal that hit the right upright and stayed out. 10 red-zone snaps, two touchdowns. Eddy Pineiro did make one from 56, so the kicking ledger reads two of three.

One more that belongs in the ledger, because it set up the first score of the second half: Deebo Samuel took the second-half kickoff back 45 yards to the San Francisco 49. Seven plays later Purdy hit Mike Evans for two yards on third and two, and with the kick it was 17 to seven.

Now the part where a Week 1 episode has to be honest about what it is. This was both teams' first game of the season, and most of the league has not played yet, so there is no this-week comparison to make. What there is, is last year. In 2025 this defense finished 20-fourth in the league in expected points allowed per play and 20-ninth in the rate of plays it allowed to succeed. It just held the offense that finished second in the league in expected points per play — and first in success rate — to seven points and a 36 percent success rate through the air. The offense, meanwhile, finished sixth a year ago and looked like that team: seven of 12 on third down, after leading the league at 51 percent last season. And the run game that ranked 20-first ran for a hundred and 74. If you want one sentence out of this: the offense looks like itself, and the defense looked like something it has not been in a while — and one night against one opponent, even this opponent, is not proof of anything. The question for the next month is whether that pass defense is a unit or a Thursday.

San Francisco is home to Miami on Sunday the twentieth. Watch whether the pass defense travels, and watch the red zone, in that order.
