The Dolphins benched Tua Tagovailoa mainly because his performance dropped sharply late in the season and the staff believes rookie Quinn Ewers currently gives them a better chance to win while also evaluating the future of the position.

What actually happened

  • Miami announced that Tua would no longer start and that seventhā€‘round rookie Quinn Ewers would take over as QB1, with Zach Wilson as backup and Tua as the emergency third quarterback.
  • Head coach Mike McDaniel explicitly said the ā€œsimpleā€ reason was that he thinks Ewers gives the team the best chance to win the remaining games, starting with the Bengals.

Onā€‘field performance reasons

  • Over roughly the last month and a half before the benching, Tua had been one of the least effective starting QBs in the league by metrics like QBR and passing production, even while the team was still winning some games.
  • He led the NFL with a careerā€‘high interception total that season, and turnovers are something McDaniel is known to strongly dislike from his quarterbacks.

Bigger picture and timing

  • By the time of the decision, the Dolphins had been mathematically eliminated from playoff contention, which reduced the incentive to keep riding a struggling veteran over a rookie they wanted to evaluate.
  • With Tua on a large, hardā€‘toā€‘move contract, the team also has to decide whether heā€™s their longā€‘term answer, a trade candidate, or an expensive backup, so getting real game reps for Ewers is part of planning for 2026 and beyond.

How Tua and the team framed it

  • McDaniel described the move as ā€œcomplicated but simple,ā€ saying it was ultimately ā€œbest for all parties involvedā€ and noting that Tua took the news hard but accepted a new leadership/support role in the QB room.
  • Reporting around the team has emphasized that while McDaniel helped elevate Tuaā€™s play in prior seasons, lingering durability and decisionā€‘making concerns plus his recent slump made this season feel like a breaking point for the organization.
