01 / Why this game matters

The short version

San Francisco opened with 379 yards and a 27-7 win, while Miami produced 259 yards, committed two turnovers and lost 27-13. The Dolphins now have to contain an offense that generated 174 rushing yards while finding more finish from their own playmakers.

02 / Know these people

Keep an eye on them

Malik Willis / Starting quarterback and secondary rushing threat

Miami Dolphins · Quarterback (QB)

Willis accounted for 220 passing yards and 39 rushing yards in Week 1, but he also completed 15 of 27 attempts with an interception. Miami needs his mobility without allowing disrupted plays to become turnovers.

Caleb Douglas / Leading Week 1 receiving producer

Miami Dolphins · Wide Receiver (WR)

Douglas turned seven targets into five catches and 94 yards. His involvement gives a proven downfield option from Miami's opener.

03 / Watch for this

One thing you can actually see

Watch which back joins on early downs and whether and Black alternate within drives. If both consistently receive carries, Miami will have to defend the same productive rushing approach against two different runners.

04 / Sound smart

A natural observation

and Kaelon Black combined for 133 rushing yards in the opener, giving San Francisco two productive backfield options.

A read on both sides

Team identity

Dolphins

Team vibe

Miami arrives 0-1 under Jeff Hafley after losing 27-13 to Las Vegas. The Dolphins had individual receiving production from and Washington, but threw an interception, was held to 36 rushing yards and the team committed two turnovers.

49ers

Team vibe

San Francisco is 1-0 under Kyle Shanahan after beating the Rams 27-7. threw three touchdown passes, the offense received substantial rushing production from both and Black, and the 49ers committed one turnover.

Current storylines

What to keep in your head

  • The 49ers did not need one back to carry the entire running game. averaged 6.8 yards on 10 carries, while Black added 65 yards on 14 attempts, allowing Kyle Shanahan to keep presenting Miami with fresh backfield options.
  • had three receivers produce at least 53 yards—, Malik Washington and Chris Bell—but finished without a touchdown pass. The question is whether that passing production can translate into scoring against San Francisco.
  • San Francisco recorded seven quarterback hits from the listed defenders in Week 1, led by 's four, despite none of those players recording a sack. That shows a front capable of affecting the quarterback even when the play does not end behind the line.

Teach Me What to Notice

On screen

Is Willis being moved off his throwing spot?

  • Malik Willis · Miami Dolphins
  • Osa Odighizuwa · San Francisco 49ers

Look for: After the snap, watch whether can plant his back foot in the middle of the pocket or must immediately slide, retreat or run outside.

If you see it: If or another 49ers defender repeatedly arrives as begins to throw, expect hurried passes or scrambling away from the original play.

Here's what it means: San Francisco's rush is controlling the passing sequence even if it does not produce sacks; Miami is reacting instead of letting routes develop as designed.

On screen

Which receiver gets the longer throws?

  • Brock Purdy · San Francisco 49ers

Look for: Compare the depth of 's throws to Mike Evans and Demarcus Robinson rather than focusing only on their target totals.

If you see it: If Evans keeps collecting shorter completions while Robinson is targeted farther downfield, San Francisco is recreating two distinct Week 1 receiving roles.

Here's what it means: Miami must defend both steady completions and chunk gains instead of concentrating its coverage at one depth.

On screen

Can Jaylen Wright change the starting field position?

Look for: On San Francisco kickoffs, locate Wright and watch whether he finds a lane beyond the first wave of coverage.

If you see it: If Wright reaches open space and Miami starts possessions well beyond its usual kickoff spot, the offense will have less field to cover.

Here's what it means: Miami's return game is creating scoring opportunities independently of an offense that struggled to finish drives in Week 1.

Miami Dolphins · Quarterback (QB)

Willis accounted for 220 passing yards and 39 rushing yards in Week 1, but he also completed 15 of 27 attempts with an interception. Miami needs his mobility without allowing disrupted plays to become turnovers.

Players & Coaches

Caleb Douglas / Leading Week 1 receiving producer

Miami Dolphins · Wide Receiver (WR)

Douglas turned seven targets into five catches and 94 yards. His involvement gives a proven downfield option from Miami's opener.

Players & Coaches

De'Von Achane / Run-and-catch backfield option

Miami Dolphins · Running Back (RB)

Achane had 11 carries for 36 yards and caught four of five targets for 30 more. His receiving usage offers Miami another way to get the ball out of ' hands.

Players & Coaches

Brock Purdy / Distributor for San Francisco's multi-part offense

San Francisco 49ers · Quarterback (QB)

Purdy completed 25 of 34 passes for 205 yards and three touchdowns in the opener. He also rushed for 29 yards, adding another element for Miami to track.

Players & Coaches

Christian McCaffrey / Primary all-purpose back

San Francisco 49ers · Running Back (RB)

McCaffrey rushed 10 times for 68 yards and received eight targets. Even when his five catches produced only 20 yards, his usage forced the defense to account for him as both a runner and receiver.

Players & Coaches

Osa Odighizuwa / Interior pocket disruptor

San Francisco 49ers · Defensive Tackle (DT)

Odighizuwa recorded four quarterback hits in Week 1. Pressure arriving through the middle could make it difficult for to remain set and deliver accurately.

The Stakes

The direct consequence is a chance for San Francisco to move to 2-0 or for Miami to avoid an 0-2 start. Beyond the records, the game will show whether Miami can narrow the Week 1 gap in rushing production and turnovers against a 49ers team that opened with a more complete offensive performance.

Why it matters

Miami's possession margin

The Dolphins gave the ball away twice in their opener, compared with one San Francisco turnover. Against an offense that generated 379 yards, giving extra possessions would increase the burden on Miami's defense.

Why it matters

San Francisco's rushing depth

The 49ers produced 174 rushing yards without overloading a single player. If both and Black remain productive, Miami will need sustained tackling from a defense whose Week 1 leaders included Jacob Rodriguez with 14 tackles and Chris Johnson with 11.

Why it matters

Miami's path to points

, Washington, and Chris Bell combined for 202 receiving yards, but none caught a touchdown. Turning that distributed yardage into scoring plays is the clearest offensive step Miami can take in Week 2.
