New York Giants at Miami Dolphins
Saturday, August 22, 2026
4:00 PM ET, Hard Rock Stadium
Saturday afternoon’s Miami game has some of the sharpest line movement on the entire Week 2 preseason board, and that movement is pointing squarely at the road team.
The Giants are 3.5-point favorites at Hard Rock Stadium with a total of 36.5. This game opened with New York as a 1.5-point favorite. Since then, the spread has moved a full two points toward the Giants, and the total has dropped a point from 37.5 to 36.5. When a preseason spread moves two points on a road favorite, sharp money is telling you something specific — the market believes the visiting team is significantly better than the opening number suggested. Once you dig into the coaching setup and the roster context, it’s easy to understand why.
Let’s start with the sidelines.
John Harbaugh is entering his first year as the Giants head coach after 18 seasons with the Baltimore Ravens. He was hired on January 20, 2026 following the end of his Ravens tenure. First-year head coaches in their second preseason game are usually still working through installation and evaluation, but Harbaugh brought serious veteran coaching infrastructure with him. Matt Nagy, the 2018 AP Coach of the Year and former Chicago Bears head coach, is his offensive coordinator. Brian Callahan, the former Tennessee Titans head coach, is his quarterbacks coach. That’s two former NFL head coaches on the Giants offensive staff working with second-year quarterback Jaxson Dart. When you have that concentration of head coaching experience installing an offense, execution tends to be sharper earlier than most first-year regimes.
On the Miami sideline, Jeff Hafley is also in his first year as an NFL head coach. He came over from Green Bay, where he was the defensive coordinator for the 2024 and 2025 seasons, and before that he was the head coach at Boston College from 2020 to 2023. Hafley walked into a Dolphins organization that finished 5-12 in 2025 and fired Mike McDaniel. This is a franchise in transition — new head coach, new coaching staff, new offensive scheme, and a quarterback room being led by Malik Willis after acquiring him this offseason. That’s a lot of moving pieces still being sorted through, and second preseason games for franchises in that kind of rebuild typically don’t produce the sharpest execution.
The quarterback situation is worth breaking down.
Jaxson Dart got a full offseason under Harbaugh’s new staff and specifically under Brian Callahan’s tutelage as quarterbacks coach. He’s the confirmed starter for the 2026 season, and he’s the kind of dynamic playmaker Harbaugh’s coaching staff was hired to develop. Dart played meaningful snaps in Week 1 against the Vikings and, while the Giants lost, Dart showed the kind of playmaking energy that has been a hallmark of Harbaugh’s franchise-quarterback development at Baltimore over the past 18 years.
Malik Willis, meanwhile, is on his third NFL team in four years. He’s a mobile quarterback with real athletic talent, but his career passing record as an NFL starter is 3-3, and the Dolphins acquired him to compete for the starting job with a rebuilt roster. Willis played in Week 1 against Washington and the Dolphins lost. Behind him are Quinn Ewers (who went 1-2 in his final three 2025 starts) and rookie Cam Miller. That’s a QB room stuck between rebuild and reset.
The situational read backs the line movement. Both teams cycled through their entire QB rooms in Week 1. Both lost their openers. But the Giants have significantly more established veteran coaching leading their evaluation process, and they have a starting quarterback in Dart who’s built chemistry with an offensive coordinator who’s been to a Super Bowl. That’s the kind of edge that shows up in preseason games where second and third-string units decide the outcome.
The 3.5 points is a reasonable number given the coaching and quarterback advantages, and the fact that sharp money has pushed this line from -1.5 to -3.5 tells you the market has been reading the situation the same way.
I looked at the total too. The drop from 37.5 to 36.5 is modest, but 36.5 already sits in the low end of preseason totals. Two rebuilding teams with first-year head coaches likely won’t push it much higher, so there’s some case for the Under. But the side is where I see the cleaner edge given how aggressively the spread has moved.
The Pick: New York Giants -3.5
