3 Dolphins bold predictions for 2026 NFL season in Year 1 under Jeff Hafley

The Miami Dolphins are undergoing a full organizational reset in 2026, hiring first-time head coach Jeff Hafley away from his defensive coordinator post with the Green Bay Packers to replace Mike McDaniel, who went 35-33 over four seasons without a playoff win. General manager Jon-Eric Sullivan and Hafley have made it clear their mission is “chasing championships,” but this year is realistically about establishing a new identity.

The Dolphins moved on from Tua Tagovailoa in a record-setting $99.2 million dead-cap release and handed the offense to Malik Willis, betting on a ground-and-pound approach built around De’Von Achane. Here are three bold predictions for how Miami’s Year 1 under Hafley plays out.

Malik Willis Wins More Games Than Expected

Willis signed a three-year, $67.5 million contract in March and enters 2026 as the unquestioned Week 1 starter over rookie-adjacent options like Kyle McCord. Vegas and most national analysts have penciled Miami in for a rebuilding year, but Willis inherits a Dolphins offense that still ranked among the league’s most explosive skill-position groups just one season ago. Hafley’s staff has structured the offense to lean on the run and shorten Willis’s decision-making windows, a formula that worked for similarly limited passers in recent seasons.

Miami’s defense also got reinforcements in free agency, adding edge rushers David Ojabo, Josh Uche and Robert Beal Jr., all signed on modest one-year deals designed to generate more pressure than last year’s unit provided. That kind of pass-rush infusion could offset some of Willis’s inevitable growing pains as a first-time full-season starter. Expect Miami to finish closer to 7-10 than the 4-13 many preseason projections suggest, avoiding a true bottom-five finish in Hafley’s debut year.

De’Von Achane Leads the NFL in Yards From Scrimmage

Achane enters 2026 fresh off a Pro Bowl season in which he rushed for 1,350 yards on 238 carries, a league-best 5.7 yards per attempt, while adding 67 catches for 488 yards for 1,838 total yards from scrimmage. That efficiency mark led all qualified running backs and represented his first 1,000-yard rushing season since entering the league in 2023. With Miami’s offense now built explicitly around establishing the run behind a quarterback who thrives off play-action, Achane’s workload should climb even further.

Hafley’s staff has signaled they want to lean on Achane’s dual-threat skill set to mask uncertainty at quarterback, similar to how other rebuilding teams have protected first-year starters. If Achane’s touch count rises even modestly while maintaining anything close to his career 5.6 yards-per-carry average, he becomes a serious contender to lead the NFL in yards from scrimmage for the first time in his career.

Jeff Hafley’s Defense Ranks Top 12 in Points Allowed

Hafley spent the previous two seasons as Green Bay’s defensive coordinator before taking the Miami job, and his scheme emphasizes disciplined tackling and coverage disguise rather than pure talent accumulation. The Dolphins retained anchor defensive tackle Zach Sieler, who signed a contract extension through 2029, giving Hafley a proven interior presence to build around. Combined with the additions of Ojabo, Uche and Beal at the edge, Miami has quietly assembled more pass-rush juice than its offense will likely provide points.

Given Hafley’s track record of scheme-driven improvement rather than relying on star power, a jump from a defense that finished outside the top 20 in 2025 into the top 12 in points allowed is plausible. That kind of defensive leap, even amid an offensive transition, would validate the hire and give Miami a foundation to build on beyond this rebuilding year.

These three predictions all point toward the same conclusion: Hafley’s first season in Miami looks rockier on paper than it plays out on the field. If Willis provides league-average quarterback play, Achane stays featured, and the new-look pass rush generates consistent pressure, the Dolphins could surprise as a scrappy, defense-first team rather than the basement-dweller many expect.
