Mike McDaniel was fired as head coach of the Miami Dolphins primarily because team owner Stephen Ross felt the on‑field results had declined and the organization needed a broader reset after a disappointing 7–10 season and missing the playoffs.

What actually happened

  • The Dolphins dismissed Mike McDaniel on January 8, 2026, after his fourth season in Miami.
  • Miami finished 7–10 in 2025, starting 2–7 and failing to reach the postseason, which Ross viewed as unacceptable given the talent on the roster.

Ross’ stated reasons

  • Ross cited a need for “comprehensive change” in the franchise, indicating he was not comfortable continuing with the status quo after back‑to‑back underwhelming years (8–9 in 2024, 7–10 in 2025).
  • Even though he liked McDaniel’s offensive mind, Ross reportedly felt the overall results, especially in big games and late‑game situations, did not justify keeping him.

Performance and collapse

  • McDaniel finished his Dolphins tenure with a 35–33 regular‑season record and 0–2 in the playoffs, with the stronger seasons coming early in his tenure.
  • The 2025 season included multiple blown leads and a severe early‑season slump (2–7 start), which intensified scrutiny on his game management and the team’s culture.

Other factors and speculation

  • The timing of his firing aligned with John Harbaugh suddenly becoming available after leaving the Ravens, leading to speculation Miami wanted to position itself for a more experienced, Super Bowl–winning coach.
  • Reporting around the decision stresses that the move was driven by dissatisfaction with trajectory and results, with any potential Harbaugh pursuit described as a consequence rather than the sole cause.

TL;DR: Mike McDaniel was fired because the Dolphins regressed, missed the playoffs after a 7–10 season, and owner Stephen Ross decided the team needed a big organizational reset, even though McDaniel was respected for his offensive creativity.
