Los Angeles Rams at San Francisco 49ers — 2026 Week 14 | Box Score, Drive Chart & Win Probability | Dynatyze

When the Rams have the ball

Matthew Staffordagainstthe 49ers

projected starter · chart of Tue, Sep 8, 2026

Staying on schedule

LA+100

Share of first and second downs that gained enough to keep the offence ahead of the chains. Third down is downstream of this, which is why a team can convert well and still stall: it is the unit that never faces third-and-nine that wins the afternoon. This has the biggest weekly sample of the five, so its week-to-week reading is the one to trust most.

Week to week Rams's offence held its middle half of weeks between 46.8% and 59.1% over 17 weeks — 2.0 times the league's whole season spread — the season figure is a mean of afternoons that did not resemble each other. 49ers's defence held its own between 46.9% and 52.6% — 0.8 times the league's whole season spread, tighter than the league itself — a habit rather than an average of different afternoons.

the 2025 regular season · the rooms, read for these two clubs

Two identities, on the league scale

Last season, labelled as last season

There is no 2026 play-by-play at all yet — the plays are about 20 minutes after each final, with the 5:00 AM ET nightly sync behind it and the Monday 4:00 AM ET weekly sync as the audited pass, and no game has been played. So every rate below is drawn from the 2025 regular season, labelled that way on purpose rather than dressed up as a forecast for this one.

Pass rate over expected

The Over Expected Room →

How far a play-caller ran from the pass rate the situation asked for, in percentage points. A team above zero passes more than the down, distance and score script called for; a team below it runs more. A scramble counts as a pass, because the model's idea of a pass is the dropback.

Fourth downs, went for it

The Fourth Down Room →

Share of fourth downs on which the offence ran a play instead of kicking. The denominator is every fourth down with a decision on it — go, field goal or punt.

Blitz sent on defence

The Tendency Room →

Share of charted dropbacks this defence sent an extra rusher on. Charting is a separate feed from the play-by-play and it begins in 2022, so an older basis season has no blitz number at all.

Drives allowed to score

The Drive Room →

Share of opponent possessions this defence let end in points. Lower is better, and the rank reads that way — rank 1 is the stingiest defence in the league. Every possession in football is one team's drive and another team's stop, so POOLED over the league these are the same drives counted twice. The figure printed here is the unweighted mean of the qualifying clubs' rates, which is a different average: a club that faces more drives than it runs pulls the two apart, by a few hundredths over a full season and by a few tenths early in one.

Note

Shares are the mean of a player's weekly share, over the games he cleared eight snaps in — not a season total divided by a season, which would let one enormous week stand in for a role. Weeks 19 through 22 are excluded by hand: the usage table spells every row's season type REG, playoffs included, so the week bound is what keeps the postseason out.
