The Miami Dolphins’ loss to the Las Vegas Raiders opened the season with a problem that can’t be brushed aside: the run defense looked shaky, and it has to get fixed fast.
It’s only Week 2, so nobody is pretending the season is defined yet. But after giving up 130 rushing yards to Las Vegas, Miami is sitting with the NFL’s 23rd-ranked run defense, and Ashton Jeanty showed exactly how that number happened. He finished with 102 yards on 23 carries, and even though his longest run was only 15 yards, the damage was steady all game.
Jeanty didn’t need anything fancy. He kept working the middle, leaned on his physical style, and let the Raiders’ offensive line do plenty of the heavy lifting.
The blocking opened lanes, and Miami’s front never consistently closed them. Even when the Dolphins got penetration, Jeanty’s burst let him slip through and force tackles from behind, which turned into missed tackles and extra yards.
At 5-8, he doesn’t look like a back who should be shrugging off defenders, but his wide build and stiff arm made life difficult for Miami unless someone got to his legs cleanly.
"I think early on, we kind of dipped our toe in the water, and we kind of played it safe," Hafley said. "We weren't as downhill; we weren't tearing off blocks.
We were just kind of playing it safe. We had some misalignments and some fronts.
We had some misrun fits early on. I think it came - we were just a little tentative, and I think we were trying to be too safe.
I think as we got going a little bit, we were more downhill; we were tearing off blocks, and we were just more physical."
The problems up front were especially visible in the trenches. Jordan Phillips had a rough day against Raiders center Tyler Linderbaum, and that matchup helped leave open lanes right up the middle. Zeek Biggers also struggled against Spencer Burford.
Miami mostly stayed in Cover 3, with three deep defenders behind the linebackers. That left the linebackers and, at times, the safeties to clean up the run after the initial push.
The scheme helped prevent a true breakaway run - there wasn’t a carry longer than 20 yards - but it didn’t stop the Raiders from stacking up 8- and 10-yard gains that kept drives on schedule. On every touchdown drive, Las Vegas opened with runs of 11, 8 and 5 yards, quickly putting Miami behind the chains and setting up the rest of the series.
The third quarter was where the Raiders really leaned into the ground game. With a 17-6 halftime lead, they ran 12 times for 62 yards in the period, good for 5.2 yards per carry. That ground control helped them add 10 more points and helped tilt the game heavily in their favor in time of possession, where they finished with a 34:53 to 25:07 edge.
"In the second half, it was impressive how we played against the run," Hafley said. "It was really a tale of two halves.
So hopefully they got that out of their systems, and we build off of it, but there's some coaching there too now. We got to make sure we're lining up in the right spots and that we're seeing things the right way and fitting in the right areas.
So we'll get back to work and improve that."
Even that read of the game feels a little generous. The defense’s real improvement didn’t show up until the fourth quarter, and by then it was too late. Las Vegas had already settled into a conservative approach, trying to bleed the clock, while Miami’s offense struggled so badly that the fourth quarter turned into a mess of five punts and three turnovers.
Now the Dolphins turn to a much tougher challenge. San Francisco is next, and Christian McCaffrey is waiting.
But the 49ers won’t be coming at Miami with only one running back in the picture. Rookie Kaelon Black has been a major part of the mix, too.
McCaffrey, in his tenth NFL season, is still doing damage, but his role has shifted some. In the 49ers’ win over the Los Angeles Rams, he ran between the tackles seven times on 10 carries and picked up 54 of his 68 yards that way. Black handled more of the workload early and finished with 14 carries, four more than McCaffrey, as San Francisco kept CMC fresh for the second half.
That pairing worked beautifully against the Rams, where the 49ers piled up 174 rushing yards. If Miami doesn’t clean up the issues that showed up against Jeanty, it could be another long afternoon.
The Dolphins may have caught a break with Black suffering a groin injury in practice Thursday, though his status for the game is uncertain. Even if he can’t go, McCaffrey alone is more than enough to test a run defense that already looks like it needs answers immediately.

Dolphins Draft Outlook Got Real Ugly After Just One Game
A rough opening weekend has already pushed the Dolphins into an unexpected spot in the early draft conversation. After their loss to the Raiders, ESPNs Football Power Index now gives Miami the highest chance of landing a top-10 pick in next springs draft, a jarring development for a team that entered the season with much different expectations. The projections are bleak enough to make the conversation feel less like a slow-burn concern and more like an immediate reality check.
ESPNs simulations have Miami with a 38% shot at the No. 1 overall pick and an average draft position of 2.9, while the betting market is essentially treating this as a team in danger of finishing with only a handful of wins. The road ahead does little to ease the pressure, with matchups coming against the 49ers, Chiefs, Vikings and Bengals. For a club that still has plenty of football left, the bigger question now is whether the season can stabilize before the draft picture gets even uglier. [Read more 🡒]
Dolphins Face A Week 2 Test They Cant Keep Avoiding
The Dolphins came out of Week 1 looking like a team still trying to find its offensive balance. Against the Raiders, Miami ran the ball only 18 times and never really settled into the kind of rhythm that has made this offense dangerous when it is at its best. For a team built around speed and spacing, the ground game still matters, and getting De'Von Achane going behind a sturdier interior front feels like a necessary step rather than a luxury.
Week 2 offers a clearer chance to clean that up, with San Francisco's interior defensive line coming in banged up and not nearly as imposing as it usually is. Miami's next test is not just about whether the Dolphins can create more efficient rushing lanes, but whether the offensive line can help them avoid another one-dimensional afternoon. The Niners still have pass rushers who can tilt a game, but the more immediate question for Miami is whether this is the week the run game finally gets treated like a real part of the plan.

Dolphins Offense Already Faces Pressure To Prove Hafleys Identity Works
After the Dolphins season opener, Jeff Hafley made it clear where he wants this offense headed: on the ground. DeVon Achane handled 15 touches and Miami ran the ball 18 times in the first game of the 2026 season, a start that gave Hafley room to point back to his Boston College background, where his teams leaned heavily on the run and produced strong rushing numbers. For a team trying to establish a new identity, the early message was simple enough.
Now comes the harder part. Miami is heading into Week 2 against the San Francisco 49ers with the rushing attack already under the microscope, and the gap between a stated commitment and a functioning identity can close quickly in this league. The Dolphins do not need a philosophy lecture as much as they need the kind of run game that can hold up against a quality opponent and make Hafleys preferred blueprint look less like a coaching talking point and more like something the offense can actually build around.
