Dolphins Open Camp Under Jeff Hafley With De'Von Achane at the Center of the Offense

The Miami Dolphins are working through the opening stretch of a training camp that represents the clearest break the franchise has made in years. New head coach Jeff Hafley has taken over from Mike McDaniel, and camp at the Baptist Health Training Complex in Miami Gardens runs from July 28 through August 26.

Veterans reported to Miami Gardens with rookies having arrived the week prior, and Hafley reported that every player passed the conditioning test on arrival. The team began practicing shortly after, opening an installation period that will determine how much of the new system is in place by Week 1.

The offensive centerpiece is running back De'Von Achane, who is coming off a Pro Bowl 2025 season. The team has indicated it intends to run its offense through Achane, a structural choice that shapes everything from personnel groupings to protection schemes.

A coaching change with real consequences

Head coaching transitions in the NFL are rarely cosmetic. A new staff brings new terminology, new scheme concepts on both sides of the ball, new practice structures and new standards for how the roster is evaluated. Players who fit the previous system may not fit the new one, and the reverse is equally true.

Hafley arrives with a defensive background, which typically shapes how a head coach allocates his own time and how he structures the roster. Defensive-minded head coaches generally delegate offensive play-calling and invest personally in the defensive install.

The McDaniel offense in Miami was built around speed and horizontal stress, using motion and outside zone concepts to create leverage. Whatever Hafley's staff installs will be evaluated against that baseline, both by fans and by the roster that learned the previous system.

Camp is where that transition becomes concrete. The number of installations completed, the pace at which the offense operates in team periods and the volume of pre-snap communication all indicate how far along the process is.

Building around Achane

De'Von Achane's Pro Bowl 2025 season established him as a genuine focal point rather than a complementary piece. Running the offense through a back of his profile means the passing game and the run game work off the same personnel groupings, forcing defenses to declare before the snap.

Achane's value has historically come from explosiveness in space rather than volume between the tackles. An offense designed around that skill set typically leans on outside zone, screens, wheel routes and formations that create numerical advantages at the point of attack.

The durability question is inherent to any plan that increases a back's workload. Running backs who absorb high touch counts carry elevated injury risk, and how the staff manages Achane's practice reps in August is an early indicator of how they plan to manage his in-season usage.

The offensive line's performance will determine whether the plan works. Zone running schemes depend on linemen reaching and sealing defenders laterally, and communication on the interior is typically the last thing to come together during a scheme change.

The camp schedule

The Dolphins are holding eight practices open to the public plus one additional practice exclusively for season ticket members. All public practices are free to attend, which distinguishes Miami from clubs that charge or limit access.

The first public practice took place Sunday, August 2, timed to the NFL's Back Together Weekend. The team is also holding a practice at Hard Rock Stadium on Saturday, August 8, open to the public, which gives fans a look at the roster in the game-day environment.

A joint practice with the New York Giants is scheduled for Thursday, August 20 and will be open to fans. Joint practices have become a preferred alternative to preseason game snaps for coaching staffs, offering controlled competitive work against an unfamiliar opponent without the injury exposure of full game conditions.

Camp concludes August 26, after which roster cuts to the regular season limit follow league-wide deadlines.

What it means for Dolphins fans

The most important thing to watch in August is not the highlight plays but the operational details. Whether the offense breaks the huddle cleanly, whether the line communicates protection adjustments and whether the defense lines up correctly against unusual formations are the markers of a scheme install taking hold.

Preseason results correlate poorly with regular season outcomes, and coaching staffs routinely play backups extensively while keeping starters on limited snap counts. Reading too much into preseason scoring is a recurring error.

The roster construction question is whether the personnel on hand fits what Hafley wants to run. Every coaching change involves a period during which the roster is a legacy of the prior regime, and it typically takes two offseasons for a staff to shape a roster to its preferences.

Fans attending public practices should account for the heat. Heat advisories have covered much of South Florida this week with heat index values reaching 105 to 110 degrees as a Saharan dust plume suppresses afternoon storms.

Around Florida football

Miami is one of three Florida NFL clubs in camp. The Jacksonville Jaguars opened camp July 29 at the Miller Electric Center under second-year head coach Liam Coen, and the Tampa Bay Buccaneers are working through their own preparation.

The Jaguars and Buccaneers will hold joint practices in Jacksonville on August 25 and 26, followed by a preseason finale at Jacksonville on Friday, August 28. That in-state joint session gives both clubs competitive work without additional travel.

Florida college football programs are opening fall camp on a parallel timeline. The Florida Gators begin camp August 5 under new head coach Jon Sumrall, and Florida State opened with scrimmages scheduled for August 4 and August 9 under Mike Norvell.

The overlap means Florida sports coverage through August is dominated by football preparation across three NFL rosters and multiple Power conference college programs, with the state's baseball clubs simultaneously navigating a pennant race and a wild card chase.

What a scheme change asks of a roster

The players most affected by a coaching transition are rarely the stars. Established starters generally have the talent to function in multiple systems. The roster churn happens on the margins, where a player whose value was scheme-specific under the prior staff may not have a role under the new one.

Offensive linemen are the clearest example. A lineman built for a zone-blocking scheme, prioritizing lateral movement and second-level climbing, is a different player from one built for gap and power concepts requiring drive blocking at the point of attack. Neither is better in the abstract, but the fit determines whether a player is a starter or a backup.

Defensive backs face a parallel question. A corner who excels in press-man coverage may struggle in a zone-heavy system requiring pattern recognition and route distribution awareness, and vice versa. Hafley's defensive background makes the secondary an area where his preferences will be most evident.

The evaluation happens across August, and the roster reductions that follow camp reflect it. Players who fit the new scheme move up the depth chart; those who do not frequently end up elsewhere, which is why post-cut waiver claims often follow coaching changes.

The Achane workload question

Building an offense around a running back is a defensible strategy but carries specific risks that coaching staffs plan around carefully. Running backs absorb more contact per touch than any other skill position, and the correlation between high workload and injury is well documented.

Modern staffs generally manage that through complementary backs, using a second and sometimes third runner to absorb interior carries while reserving the primary back for situations where his particular skills matter most. Whether Miami has that complementary piece is one of the questions August should answer.

Achane's Pro Bowl 2025 season established what he does well: creating explosive plays in space, both as a runner and as a receiver out of the backfield. An offense that maximizes those opportunities looks different from one that simply increases his carry count.

The passing game usage is where the plan may show up most clearly. Backs who threaten defenses as receivers force defenses into personnel decisions before the snap, which creates leverage for the rest of the offense. Watching how often Achane aligns outside the backfield during camp team periods is one indicator of how the staff intends to use him.

What free camp access means in Miami Gardens

The Dolphins holding eight public practices free of charge is a deliberate community relations decision at a moment when the franchise is asking its fan base for patience through a transition.

Access policies vary widely across the NFL. Some clubs charge for camp attendance, some limit it to season ticket holders, and some hold camp at remote facilities that make attendance impractical for most local fans. Miami's approach keeps the roster visible during the period when a new coaching staff is establishing its identity.

The August 8 practice at Hard Rock Stadium is the highest-profile of these sessions, moving the operation from the training complex to the game-day venue. Practices in stadium environments carry logistical value for the team as well, letting the staff work through gameday communication and operations.

The additional session reserved for season ticket members reflects the commercial reality underneath the community access. Retaining season ticket holders through a coaching transition and a rebuilding stretch is a genuine business challenge, and exclusive access is one of the few tools available that costs the club little.

What's next

The public practice at Hard Rock Stadium on August 8 is the next scheduled open session, followed by the joint practice with the Giants on August 20 and the conclusion of camp on August 26.

Roster decisions follow camp. NFL clubs must reduce to the regular season roster limit by league deadline, and the practice squad is assembled from players cleared through waivers afterward.

Injury management through the remainder of camp will shape the depth chart. August injuries to key contributors are the most common way a promising camp turns into a difficult September.

The regular season opener will be the first genuine measure of how far the Hafley install has progressed. Until then, camp observations are inputs rather than conclusions.
