01 / Why this game matters
The 3-0 49ers enter with an offense that generated 437 yards last week, while the 2-1 Broncos bring a defense that had four different players record a sack. Watch whether Denver can disrupt before San Francisco’s collection of playmakers takes over.
02 / Know these people
Brock Purdy / Distributor for San Francisco’s productive passing attack
San Francisco 49ers · Quarterback (QB)
Purdy threw for 297 yards and four touchdowns without an interception last week, and he added 34 rushing yards. Denver’s pressure will test whether he can maintain that efficiency when defenders arrive quickly.
Christian McCaffrey / Dual-purpose runner and receiver
San Francisco 49ers · Running Back (RB)
McCaffrey turned 15 carries and five targets into 116 scrimmage yards and a rushing touchdown against Arizona. His ability to contribute on handoffs and passes gives Denver multiple responsibilities on the same possession.
03 / Watch for this
Watch whether RJ Harvey releases into open space for short throws when faces pressure. Harvey caught six of seven targets for 41 yards last week, so repeated early checkdowns would show Denver using the backfield as a dependable passing outlet.
04 / Sound smart
caught six of seven targets for 82 yards and two touchdowns last week, making him the clearest player to track near the goal line.

Teach Me What to Notice
On screen
Look for: Watch the middle of San Francisco’s offensive line immediately after the snap and see whether Denver’s interior defenders push blockers backward toward .
If you see it: If has to move, reset his feet or release the ball earlier than intended, Denver’s rush is affecting the play even without a sack.
Here's what it means: Consistent inside pressure would make it harder for longer routes to unfold and could prevent from comfortably distributing the ball among , Evans and the other targets.
On screen
Look for: Before the snap, locate and watch whether he stays behind , shifts outside or leaves the backfield after the ball is snapped.
If you see it: If Denver linebackers and safeties move toward , look for the resulting space available to or a wide receiver; if they hold back, San Francisco can keep feeding underneath or on the ground.
Here's what it means: Those defensive reactions show which part of San Francisco’s offense Denver is prioritizing and which option may be able to exploit.
On screen
Look for: Check the down-and-distance graphic after Denver’s first- and second-down plays, especially following carries by J.K. Dobbins.
If you see it: If Denver repeatedly faces third-and-short, its full playbook remains available; frequent third-and-long situations let San Francisco anticipate a pass.
Here's what it means: Manageable third downs would indicate Denver is sustaining possessions rather than asking its defense to handle San Francisco’s offense after quick series.

Denver Broncos · Quarterback (QB)
Nix completed 17 of 34 passes for 186 yards, two touchdowns and one interception last week. He must find more consistent completions against a San Francisco defense playing without Nick Bosa.
Players & Coaches
Denver Broncos · Defensive Lineman (DL)
Allen registered five quarterback hits in Week 3, along with a sack. If he repeatedly gets into ’s space from the middle, San Francisco may have less time to develop throws to its varied targets.

San Francisco 49ers · Linebacker (LB)
Warner recorded 17 tackles against Arizona. He is the San Francisco defender casual viewers are most likely to see converging on Denver’s running backs and underneath receivers.
The Stakes
This regular-season game tests San Francisco’s unbeaten start against a Denver team one game behind in the standings and coming off its own win. A 49ers victory would extend their start to 4-0, while a Broncos win would move Denver to 3-1 and hand San Francisco its first loss; a tie remains possible.
Why it matters
Denver’s defense now faces a 49ers attack coming off 437 yards and six offensive touchdowns. Its ability to turn pressure into disrupted throws is the most direct route to keeping that production down.
Why it matters
The Broncos scored 30 points last week while totaling 257 yards. Against San Francisco, longer and more efficient possessions would reduce how often , and get opportunities.
Why it matters
Bosa and Mykel Williams are out, and White is questionable. How the remaining front generates pressure could shape whether is forced into another low-completion outing or receives time to connect with Sutton and Waddle.
