Miami Dolphins Begin Jeff Hafley Era with OTA Phase 3 Opener

The Miami Dolphins kicked off Phase 3 of their organized team activities on May 18, marking the first on-field football work of the Jeff Hafley era at the team's Baptist Health Training Complex in Miami Gardens. The opening session drew the full active roster and a handful of front-office staffers as Hafley, who was hired in January, began installing his new system across both sides of the ball.

The 2026 OTA window will run through May 29, with mandatory minicamp slated for June 2 through June 4. According to the team's offseason program release, the Dolphins have expanded to nine OTAs this year, one short of the maximum allowed under the collective bargaining agreement. The extra session signals how much teaching the new staff feels it needs to compress into the spring before training camp opens in late July.

For a fanbase that has watched four head coaching transitions in just over a decade, the start of Hafley's tenure carries weight far beyond a typical Phase 3 walk-through. Miami is coming off a 6-11 season that ended with Mike McDaniel's dismissal in early January, and ownership has made clear that the goal in 2026 is to return to the postseason for the first time since the 2023 wild-card round loss in Kansas City.

How Hafley Reached Miami

Hafley arrived in South Florida after spending the previous two seasons as the defensive coordinator for the Green Bay Packers, where his unit climbed from 24th in scoring defense to 10th in his second year. Before Green Bay, he was the head coach at Boston College from 2020 to 2023, compiling a 22-26 record over four seasons with the Eagles. His NFL background also includes defensive backs coaching stints with the Cleveland Browns, Tampa Bay Buccaneers, and San Francisco 49ers.

The Dolphins targeted Hafley as part of a broader pivot away from the offensive-minded McDaniel model. According to general manager Chris Grier's introductory press release, the franchise wanted a coach who could rebuild the defensive identity that had eroded across the past three seasons while still maximizing the speed-based offensive personnel already on the roster. Hafley's hire was announced on January 21 following a second-round interview that included team owner Stephen Ross.

His coordinator hires reinforced that vision. Former Houston Texans passing-game coordinator Bobby Slowik was named offensive coordinator, and former Las Vegas Raiders linebackers coach Patrick Graham took over as defensive coordinator. Special teams coordinator Danny Crossman, the lone holdover from the McDaniel staff, was retained for continuity.

What Phase 3 Looks Like

Phase 3 of the offseason program is the only portion in which teams can run 11-on-11 drills, though contact remains prohibited and no live tackling is permitted. The Dolphins opened Monday's session with individual position work before transitioning to seven-on-seven and team periods. Quarterback Tua Tagovailoa was present and took the majority of first-team snaps, working primarily with new wide receivers coach Tyke Tolbert.

Wide receivers Tyreek Hill and Jaylen Waddle both participated in the workout, ending speculation that either would skip voluntary sessions. Hill, who was the subject of trade rumors during the spring before signing a restructured deal in March, took reps with the first team throughout the opening period. Waddle, who is entering the second year of his four-year extension, ran routes opposite Hill and rookie second-round pick Jalen Royals.

On the defensive side, Graham worked extensively with the front seven, walking through gap responsibilities in the new 4-3 base alignment. Edge rusher Bradley Chubb was a full participant after missing most of the 2025 season with a torn ACL, his first team work since November 2024. Cornerback Jalen Ramsey, acquired from the Pittsburgh Steelers in an April trade, rotated between outside and slot reps under defensive backs coach Renaldo Hill.

Tagovailoa's Role in the New Offense

Slowik's offense will look meaningfully different from what Tagovailoa ran under McDaniel. Where the previous scheme relied on heavy pre-snap motion and wide-zone runs, Slowik's playbook leans on play-action concepts off inside-zone looks and uses condensed receiver splits to stress underneath coverage. According to the offensive installation schedule shared with reporters, the staff plans to dedicate the first two weeks of OTAs to the run game and play-action passing concepts before opening up the dropback portion of the offense.

Tagovailoa's spring carries its own pressure. The 28-year-old quarterback is in the third year of the four-year, $212.4 million extension he signed in 2024, and he is coming off a season in which he missed three games with concussion-related issues. The Dolphins have stated publicly that he remains the franchise quarterback, but the team also drafted Tulane's Darian Mensah in the third round of the 2026 draft as developmental insurance.

Backup quarterback Mike White returns for a third season in Miami, and Hafley confirmed in his post-practice address that the quarterback room would carry four arms into training camp. Mensah handled the bulk of late-period reps with the third team on Monday, working primarily on RPO concepts that figure to be a staple of Slowik's red-zone packages.

Defensive Identity Reset

Graham's defense represents the sharpest schematic break from the McDaniel era. The Dolphins ran a hybrid 3-4 under former coordinator Anthony Weaver and finished the 2025 season ranked 27th in points allowed at 25.1 per game. Graham's preferred 4-3 over front with single-high coverage shells should better fit the personnel Miami has invested in over the past two drafts, particularly defensive tackle Zach Sieler and edge rusher Chop Robinson.

Linebacker Jordyn Brooks, who signed a three-year deal in 2024, takes on a featured role as the Mike linebacker in the new scheme. Brooks led the Dolphins in tackles in 2025 and projects as the play-caller on defense. He worked alongside second-year linebacker Mohamed Kamara, who is competing for the strong-side role vacated by David Long's free-agent departure to Carolina.

In the secondary, the Ramsey trade gives Miami a true No. 1 corner for the first time since Xavien Howard's release after the 2023 season. Free agent signing Justin Reid, who joined from the Kansas City Chiefs on a three-year contract, takes over as the starting strong safety alongside returning free safety Jevon Holland. The combination represents the most experienced safety tandem the Dolphins have fielded since the 2018 season.

The Front Office's Long View

Grier remains in his post as general manager, despite reports during the McDaniel firing that ownership had considered a broader front-office overhaul. His decision to lean on a defensive-minded head coach rather than another offensive replacement reflects a deliberate shift in roster construction. The Dolphins traded down twice in the first round of the April draft, accumulating an additional 2027 second-round pick and a 2026 fourth-rounder in the process.

The cap situation gives the new staff room to maneuver. After Hill's restructure and the post-June 1 designation on the Howard release executed in 2024, Miami enters the season with roughly $12 million in effective cap space, with another $18 million available through standard restructure mechanisms if midseason injuries require veteran additions. According to the team's transaction log, the Dolphins still have two open roster spots ahead of mandatory minicamp.

Ross addressed the franchise's direction in a written statement issued before the first OTA. The owner acknowledged that the past three seasons had not met the standard he set when he hired Grier in 2016, but emphasized that the Hafley hire represented a long-term commitment to building through defense and player development rather than chasing free-agent splash signings.

What to Watch Through Minicamp

The next three weeks of OTAs will offer the first real look at how Hafley's vision translates onto the practice field. The most-watched storylines through the rest of the spring include the developing rapport between Tagovailoa and Slowik, the integration of Ramsey into Graham's coverage shells, and the recovery progression for Chubb as he ramps toward training camp.

The Dolphins also have several positional competitions worth tracking. The starting right guard spot, vacated when Robert Hunt signed with Carolina in 2024 and not adequately replaced in 2025, will be contested between veteran Liam Eichenberg and third-round rookie Jonah Savaiinaea from Arizona. The kicker job remains open after Jason Sanders' release in February, with second-year specialist Joey Slye and undrafted free agent Tyler Loop competing through camp.

Mandatory minicamp on June 2 through June 4 will mark the final on-field work before the six-week summer break. Training camp opens on July 22 in Miami Gardens, with the preseason opener against the Atlanta Falcons set for August 8 at Hard Rock Stadium. The regular season begins on September 13 with a home game against the Indianapolis Colts, the opener Hafley has circled as the first true measure of the rebuild.

South Florida Reaction to the New Era

The opening of Phase 3 also drew the largest media contingent at the Baptist Health Training Complex since the McDaniel era began in 2022. Local broadcast outlets across South Florida sent crews to cover the first on-field session, and the team made all coordinators and select position coaches available for post-practice questions. According to the team's media availability schedule, the practice schedule will be open to credentialed reporters for two of every three OTA sessions through May 29.

Season ticket renewals reflect the cautious optimism in the fanbase. The Dolphins reported a renewal rate of 91 percent in early May, slightly above the franchise's five-year average. The team also moved roughly 1,800 new full-season packages between February and the end of April, with the new-buyer activity concentrated in the upper-bowl sections of Hard Rock Stadium. Single-game tickets for the opener against the Colts went on sale on May 15 and sold through the first six rows of the lower bowl within 90 minutes.

The training complex itself underwent a series of upgrades during the spring. The Dolphins added a new defensive position room to accommodate Graham's installation work, expanded the players' lounge with a video review setup designed in coordination with the analytics staff, and replaced the artificial turf on the primary outdoor practice field. The facility improvements, which the team funded through its capital expenditure budget rather than the new coaching staff's resources, were completed by April 30 in advance of the Phase 3 opening.

The Dolphins also restructured their player nutrition and recovery operation in coordination with Hafley's preferences. The team brought on a new sports science director who had worked alongside Hafley in Green Bay, and the position group meeting rooms were rewired with the same video software the Packers used during the 2025 season. Players returning from the McDaniel era have been required to attend abbreviated weekly meetings with the sports science staff to set baselines for individual recovery protocols. According to the team's player communications release, the new program is voluntary during the offseason but will be mandatory once training camp opens. Players have responded positively to the changes through the first three weeks of the offseason program, with veteran cornerback Kader Kohou serving as the unofficial player representative for the recovery group.
