San Francisco 49ers at Los Angeles Rams: The Early-Down Passing Edge

Early-down passing will decide the 49ers-Rams Melbourne opener before either offense reaches the third-down situations that usually dominate the broadcast. The NFL and both clubs have confirmed the NFC West rivals will play at the Melbourne Cricket Ground on September 11 local time. Yet the historic venue does not change the central football problem. First down still tells the defense almost nothing and gives the offense almost everything.

Kyle Shanahan can open with Christian McCaffrey and Kyle Juszczyk in the backfield, shift one of them outside and force Los Angeles to reveal its coverage. Sean McVay can answer with a condensed formation, sell a run to Kyren Williams and give Matthew Stafford an immediate throwing lane behind the linebackers. Neither coach wants to wait until third-and-eight, when Jared Verse or Nick Bosa can ignore the run and attack.

The advantage belongs to the offense that throws before the defense expects it. Win first down through the air, and every formation remains dangerous. Waste it, and the pass rush takes control.

Why First Down Creates Real Leverage in the 49ers-Rams Melbourne Opener

Third down decides whether a drive continues. First down decides how hard that conversion becomes. A six-yard completion leaves the offense free to run, throw, use play action or move the pocket. Lose yardage, and those choices disappear.

The 49ers showed how valuable that freedom could become throughout 2024. Football Database’s situational splits credited San Francisco with 155 completions on 218 first-down attempts, a 71.1 percent completion rate. Those throws gained 2,156 yards. Los Angeles completed 158 of 230 first-down passes for 1,746 yards.

Volume alone does not establish superiority. It does show how often both coaches used the opening down to create manageable situations rather than merely run into a waiting front. Early-down passing worked because each defense still had to respect the backfield.

McCaffrey can punish a light box on the next snap. Williams can turn a crease into a chain-moving run. That threat pulls linebackers downhill and makes the window behind them easier to attack.

The numbers also expose the cost of predictable play-calling. NFelo rated San Francisco at plus-0.12 EPA per pass in 2024, compared with roughly neutral value on rushing attempts. Pro Football Focus later measured the Rams at plus-0.025 EPA per offensive play. Passing gave both teams their best route to meaningful gains, but the run threat created the picture each quarterback wanted.

Neither coach needs to abandon balance. They need to use balance as leverage.

Shanahan’s Best Evidence Came at SoFi

San Francisco’s opening drives in Week 3 of 2024 offered the clearest version of the plan. Shanahan attacked before the Rams could settle into their calls, and Brock Purdy found Jauan Jennings for touchdowns on the first two possessions.

The first score came from 13 yards. Purdy added another from four yards late in the opening quarter, then hit Jennings for a 31-yard touchdown after halftime. San Francisco’s official recap credited Jennings with 11 catches for 175 yards and three touchdowns, all career highs at the time.

Those numbers grew from more than one receiver winning isolated routes. Shanahan used motion and backfield action to make defenders process several threats at once. Purdy delivered on time, often before the Rams’ young pass rush could affect the pocket.

The result looked comfortable for most of the afternoon. San Francisco scored touchdowns on its first two series and carried a 14-0 lead into the second quarter. Los Angeles possessed the ball for only 3:19 during the opening period.

That early control should have decided the game. It did not.

The 49ers stopped producing touchdowns after Jennings’ third score. Los Angeles generated pressure without depending on heavy blitzes, while Verse, Byron Young and Braden Fiske began compressing Purdy’s space. A missed 55-yard field goal then gave Stafford another chance with the Rams trailing by seven.

Stafford hit Tutu Atwell for 50 yards on the next play. Williams scored three snaps later, and Los Angeles eventually won 27-24 on Joshua Karty’s field goal with two seconds remaining.

The comeback did not disprove San Francisco’s approach. It showed why Shanahan must sustain it. Early-down passing built the lead, but later drives lost the same clarity. Once the 49ers fell behind schedule, the Rams’ front could attack without hesitation.

How 21 Personnel Motion Unlocks the 49ers-Rams Melbourne Opener

Shanahan’s 21-personnel package places two backs and one tight end on the field. The label sounds traditional. Its alignment rarely stays that way.

Juszczyk can begin at fullback and shift into the slot. McCaffrey can motion outside, taking a linebacker with him or exposing a zone adjustment. George Kittle can align beside the tackle, then release up the seam. Jennings supplies the physical in-breaking routes that punish defensive backs playing with outside leverage.

Purdy becomes most dangerous when those movements answer his coverage questions before the snap. If a linebacker follows McCaffrey wide, he sees man coverage. When the secondary bumps across the formation, zone becomes more likely. That information lets him work quickly instead of waiting for the picture to clear after the snap.

The same package can create three different plays without a substitution. San Francisco can run McCaffrey against a lighter box, throw a quick out to the motion receiver or use play action to hit Kittle behind the linebackers.

That flexibility must drive the Melbourne plan. Early-down passing should not mean dropping Purdy into static shotgun formations 30 times. Shanahan can throw from the same looks that make the Rams brace for outside zone.

McVay Builds Conflict from Condensed Formations

McVay reaches the same destination through a different route. His formations often pull receivers tight to the offensive line, narrowing defensive spacing before the snap. That alignment creates traffic, disguises releases and gives Stafford room to attack either side.

Multi-tight-end formations add another layer. A defense that answers with heavier personnel gains strength against Williams but loses speed in coverage. Stay in nickel, and Los Angeles can run directly at a smaller box. For McVay, early-down passing turns that personnel dilemma into an immediate coverage test.

The Rams maintained that tension throughout 2024. Their own season review found that the passing attack posted its third-best success rate of the McVay era. The rushing game tied for its second-best success rate under him. Los Angeles did not produce constant explosive plays, but it stayed on schedule often enough to preserve both sides of the call sheet.

Stafford still supplies the aggression. He can hold the middle safety with his eyes, reset his feet and fire to Puka Nacua before the coverage closes. Against San Francisco in December 2024, one such connection changed an otherwise miserable night for both offenses.

Rain had reduced the rematch to punts and field goals. The Rams gained only 89 net yards in the first half, while San Francisco managed 108. Neither team scored a touchdown.

With the score tied in the fourth quarter, Stafford found Nacua for 51 yards down the right side. The completion carried Los Angeles from its own territory to the San Francisco 16, setting up the field goal that produced the Rams’ first lead. Nacua finished with seven catches for 97 yards.

That play captured the value of passing before the down becomes obvious. San Francisco still had to respect Williams, who carried 29 times for 108 rushing yards. The run game did not dominate, but it kept the defense connected to the line of scrimmage long enough for Stafford to strike outside.

How Pass Rush Dynamics Change the 49ers-Rams Melbourne Opener

Both offenses understand the punishment for wasting early downs. The Rams generated a 35.2 percent pressure rate during the 2024 regular season, according to Next Gen Stats data published by the team. Verse led the front with 73 pressures entering Week 18, fourth most in the league and first among rookies.

That group does not need a blitz package to wreck a drive. Young can threaten the outside shoulder while Fiske attacks the interior gap. Kobie Turner adds power through the middle, forcing quarterbacks away from their preferred launch point.

San Francisco encountered the full problem during the rainy December loss. Purdy’s deep fourth-quarter attempt for Jennings ended in an interception, and Christian Rozeboom sacked him on the final snap. The Rams won 12-6 without scoring a touchdown.

Purdy cannot spend the Melbourne opener waiting for third down to rescue the offense. Screens, quick in breakers and running-back option routes can force the Rams’ rushers to hesitate. Once Los Angeles widens to defend those throws, McCaffrey receives cleaner rushing angles.

Stafford faces the same calculation against Bosa and San Francisco’s front. A slow-developing pass on second-and-long gives the edge rushers permission to ignore every run key. Quick early completions keep them reading instead of charging.

Linebacker Fred Warner becomes central to that fight. McVay will try to move his eyes with backfield action, then throw into the space he leaves. Warner’s ability to diagnose the fake without surrendering depth could determine whether Stafford finds Nacua in stride or checks the ball underneath. The defensive goal sounds simple: reach third-and-long. Early-down passing exists to prevent it.

Why Early Rhythm Will Decide the 49ers-Rams Melbourne Opener

The NFL scheduled kickoff for approximately 10:35 a.m. in Melbourne, 17 hours ahead of California. Travel will alter sleep, recovery, meetings and pregame routines for both teams. The first scripted series offers the fastest route back to familiar football.

For Purdy, rhythm could begin with a quick completion after McCaffrey’s motion pulls a linebacker outside. Stafford may find it through a play-action throw from a condensed set. Neither pass needs to produce a highlight. Five or six yards would preserve the full second-down menu.

Communication will also matter inside a stadium that holds more than 100,000 spectators. Motion must finish before the snap. Protection calls must reach every lineman. One false start can turn a flexible second-and-four into a predictable passing down.

The previous meetings offer both warnings. San Francisco threw efficiently and built a 14-point lead at SoFi, only to lose control when its later drives stalled. Los Angeles endured the opposite experience in Santa Clara, leaning on Williams until one Stafford-to-Nacua strike broke open a rain-soaked game.

Early-down passing connects those two results. It gives Shanahan a way to protect Purdy from the Rams’ front without becoming conservative. McVay can use it to slow San Francisco’s rush while preserving Williams as a real threat.

Melbourne supplies the historic stage, but the early-down passing edge will carry more weight than the setting. Which coach will trust his quarterback to throw while the defense still expects the run?
