Dolphins vs. 49ers prediction: Odds, expert picks, QB matchup, injury update, betting trends, and stats

The San Francisco 49ers (1-0) take to the field Sunday at home after a dominant season-opening victory over the Rams in Australia, while the Miami Dolphins (0-1) arrive at Levi’s Stadium following a disappointing road loss to the Raiders.

The Raiders controlled much of the game from the outset against the Dolphins last weekend in Vegas, marching 93 yards on their opening drive and building a 17-6 halftime lead. Miami struggled to establish its running game and allowed consistent pressure on quarterback Malik Willis. The Dolphins’ biggest bright spot came in the third quarter. After rookie safety Michael Taaffe intercepted Kirk Cousins, Willis engineered a quick scoring drive and finished it himself with a 14-yard touchdown run, trimming the deficit to 17-13. Las Vegas unfortunately for Miami answered immediately and pulled away from there, winning 27-13. The biggest concern has to be Miami’s offensive line. Willis absorbed five sacks and frequently faced pressure, a troubling sign heading into a matchup with Nick Bosa and San Francisco’s defensive front.

Few teams made a louder opening game statement than San Francisco. Playing in Melbourne, Australia, the 49ers fell behind 7-3 early but scored the final 24 points of the game, winning 27-7. The Niners defense shut down Matthew Stafford and the Rams over the final three quarters while Brock Purdy was Brock Purdy, efficiently directing an offense loaded with playmakers. A turning point ironically came after one of Purdy’s lone mistakes, an interception. Instead of allowing momentum to swing permanently, San Francisco responded with touchdown drives on three of its next four possessions.

Bottom line: There is little reason to think Miami makes a game of this one UNLESS you believe fatigue from the trip to Australia hits the Niners on Sunday.

Player Prop to consider: George Kittle is questionable for the game, but should he dress, consider taking the OVER on 3.5 receptions. He’s hit the Over on 3.5 receptions in 80% of his last 10 games, averaging 5.2 catches over that stretch.

Let’s dive into the numbers and see if we can’t find an additional sweat or two.

Our model calculates projections around each moneyline, spread and over/under bet for every game on the NFL calendar based on data points like past performance, player matchups, betting trends, and weather forecasts.

Once the model is finished running, we put its projection next to the latest betting lines for the game to arrive at a relative confidence level for each wager.

Here are the best bets our model is projecting for Sunday’s game between the Dolphins and the 49ers:

• Moneyline: NBC Sports is staying away from a play on the Moneyline.
• Spread: NBC Sports is staying away from a play on the Spread.
• Total: NBC Sports is leaning towards a play on the Total UNDER 44.5 but recommended if the Total climbs to 45.5.

The single most important factor in this game is how badly the Dolphins’ offense matches up with San Francisco’s defense. Miami managed just 220 passing yards in its 27-13 loss at Las Vegas, and Malik Willis was sacked five times while throwing an interception. Five sacks and a pick stalled too many drives — the Dolphins’ only touchdown came in garbage time.

The 49ers’ defensive profile is exactly the kind that keeps totals low. They ranked 13th in points allowing (21.82 per game), 8th in carries allowing (24.94 per game), 8th in rushing touchdowns allowing (0.76 per game), and 6th in yards per reception allowed (10.73). They also ranked 8th in tackle efficiency (91.44) and 8th in missed tackle rate (8.56%). The concern for the Under is San Francisco’s pass rush, which ranked 32nd in sacks (20), 32nd in sack rate (3.42%), and 31st in pressure rate (18.32%) last season. But against a Dolphins offensive line that just allowed five sacks to the Raiders, even a mediocre pass rush should be able to generate pressure. And Miami’s inability to convert on third down (34.9%, 27th) means drives will stall regardless.
