Jeff Hafley has a real chance to turn the Miami Dolphins around. But it will not be quick or simple. He took over in January 2026 after Mike McDaniel was fired following a 7-10 season and consecutive missed playoffs.
Hafley arrived with a strong defensive track record from two years as Green Bay’s coordinator. His units ranked well in yards allowed, points, and takeaways. Also, he brings four seasons of head-coaching experience at Boston College. That NFL future odds combination of NFL scheme knowledge and actual program leadership is more than many first-time NFL head coaches possess.
Of course, the Dolphins he inherited clearly needed a reset. The previous regime leaned heavily on speed and skill players. The defense lagged, and the results never matched the talent. Hafley and general manager Jon-Eric Sullivan worked together in Green Bay. Now they have already shifted the identity toward physicality, size, and toughness.
They cleared significant salary-cap space by moving on from several high-profile veterans. Instead, they stocked the roster with younger players and draft picks. The goal is to build through the draft and development rather than chase big free-agent names.
2026 Miami Dolphins Head Coach Jeff Hafley Takes Command
On the field, the early signs are mixed but intentional. Hafley has spent time learning the offense. Instead of simply defaulting to defense, working closely with coordinator Bobby Slowik. While letting Sean Duggan handle the defensive installs for now. He plans to take a heavier hand on defense once the season arrives.
The quarterback situation remains unsettled with Malik Willis getting the bulk of the first-team work. At the same time, the running game will lean heavily on De’Von Achane. The roster is one of the youngest in the league, which means online wagering growing pains are inevitable.
What gives Hafley a legitimate NFL betting shot is his emphasis on coaching, culture, and detail. To illustrate, players who worked with him in Green Bay spoke well of his teaching ability and energy. He has stressed that practice is where mistakes and growth happen, and he is trying to build a more connected, accountable locker room. The Packers’ connection with Sullivan should help on the personnel side. And the defensive expertise should lift a unit that has been a consistent weakness.
Still, the path is steep. Miami has not won a playoff game since 2000, the longest drought in the league. In turn, the AFC East remains competitive, and a young roster will take time to gel.
Hafley’s college record at Boston College was modest. Translating defensive coordinator success into full-team leadership is never automatic. Thus, the defense must improve markedly. Additionally, the running game must stay productive as the young talent develops. If so, the Dolphins can become competitive within two or three years.
A full turnaround into sustained contender status will require consistent drafting, health, and Hafley’s ability to grow as a head coach in real time. The foundation is indeed being laid differently than before. Whether it holds is the test still ahead.
Stephen Ross is a major part of the problem, though not the only one. Since becoming majority owner in 2009, the Dolphins have gone 131-146 with just three playoff appearances and zero playoff wins. That stretches the franchise’s drought without a postseason victory to more than a quarter century, the longest in the NFL.
Under his watch, the team has cycled through multiple general managers and a string of head coaches. Most of them first-timers with no prior NFL head-coaching experience. As a result, the pattern has produced occasional competitive seasons that never turned into sustained success or even a single playoff win.
