San Francisco’s 3-0 start and nearly 33 points per game make its offense the headline, but Denver has allowed just over 23 per game while opening 2-1. That contrast gets to the heart of this matchup: can the Broncos disrupt the 49ers early, or will San Francisco’s balance create enough separation to cover a modest spread?
Denver’s defense meets a rolling 49ers offense
Brock Purdy threw four touchdown passes and finished with 297 passing yards in San Francisco’s 36-30 win over Arizona. The 49ers moved to 3-0, though allowing 30 points kept the game competitive into the closing minutes.
Denver took a very different route last week. The Broncos trailed the Rams 16-0 at halftime before rallying for a 30-26 victory. Bo Nix threw two touchdown passes during the comeback, while Talanoa Hufanga produced a pick-six and a game-sealing interception. It was an impressive recovery, but another slow start would be especially dangerous against an offense that has scored at least 27 points every week.
There’s also a fresh availability concern on the San Francisco side. Linebacker Dre Greenlaw is questionable with a quadriceps injury after missing Wednesday’s practice. His status adds uncertainty to a 49ers defense that has already allowed 30 points twice this season.
What the spread and projections suggest
The latest line makes San Francisco a three-point home favorite. That’s a relatively modest spread for an unbeaten home team and reflects the respect Denver’s overall profile commands despite an uneven first three weeks.

Our yardage projections also keep the teams fairly close. San Francisco is projected for about 331 total yards compared with roughly 317 for Denver. The 49ers hold similarly small advantages through the air, 224 yards to 216, and on the ground, 108 to 101.
Those gaps don’t point to an obvious mismatch. San Francisco’s case rests on its steadier scoring production, while Denver’s counter is its ability to create high-impact defensive plays and stay close enough for Nix and the offense to respond. The 47.5-point total reflects the 49ers’ hot start, but results ranging from San Francisco’s 27-7 win to last week’s 36-30 game show how much the scoring environment can shift.
Final assessment
San Francisco brings the cleaner early-season résumé and a slight edge in both the market and our yardage projections. Denver’s defense is the main counterweight, especially after its playmakers turned last week’s game with late takeaways. The factor that matters most is whether the Broncos can disrupt Purdy early; if they can’t, asking their offense to erase another substantial deficit is a much tougher proposition against this 49ers attack.
