Miami Dolphins

• 1. Introduction

  ›

  The Miami Dolphins have played exactly one perfect season in NFL history, finishing 17-0 in 1972 and winning the Super Bowl. No team has matched that record since. But the story of the franchise is bigger than one magical year. It starts with a lawyer named Joe Robbie and a comedian named Danny Thomas, who paid $7.5 million for an AFL expansion franchise in 1965. It passes through two consecutive Super Bowl titles, a quarterback who broke nearly every passing record in the book, and a long stretch of mediocrity that still hasn't fully ended. How did a team from the AFL's bottom tier become one of the most dominant franchises in football history? And how did that dynasty fall apart so completely after the men who built it walked away?

• 2. From the AFL to the NFL

  ›

  Joe Robbie was an attorney and politician. Danny Thomas was best known as an actor and comedian. Between them, they founded a franchise that didn't quite fit in. The Dolphins joined the AFL in 1966 as the only member of the AFC East that was not a charter AFL team. Florida had gone without professional football since the Miami Seahawks played a single season in the All-America Football Conference in 1946, before eventually becoming the first version of the Baltimore Colts. The Dolphins' earliest training camps were held at St. Pete Beach, with August practices taking place at Boca Ciega High School in Gulfport. Later, the team trained at Saint Andrew's School, a private boys boarding prep school in Boca Raton. In those first four seasons under head coach George Wilson, Miami compiled a 15-39-2 record, making them the worst team in the league. That losing run created the opening for the man who would define the franchise for the next quarter century.

• 3. The Shula Era

  ›

  Don Shula arrived in Miami from the Baltimore Colts, where he had lost Super Bowl III two years earlier to the AFL's New York Jets. Shula was a Paul Brown disciple, and he transformed the Dolphins into a championship organization almost immediately. After the AFL-NFL merger placed Miami in the AFC East in 1970, Shula's teams posted losing records in only two of his 26 seasons as head coach. The peak came in 1972, when the Dolphins ran the regular season table at 14-0, then ran through the playoffs and Super Bowl VII to finish 17-0. No team in professional football has recorded an unblemished season since. The Dolphins backed it up the following year with a 15-2 record and another Super Bowl title, defeating the Minnesota Vikings in Super Bowl VIII. That made Miami the first team to appear in three consecutive Super Bowls and the second team to win back-to-back championships. The fight song that accompanied those seasons had been brought to the team by a songwriter named Lee Ofman, who approached the Dolphins before the 1972 season because he wanted music to inspire his favorite team. Its association with back-to-back titles made it an institution. Shula's record of NFL coaching victories is represented by the number 347, which appears in place of a jersey number on his plaque at Hard Rock Stadium's Ring of Honor.

• 4. Dan Marino's Record Years

  ›

  Dan Marino joined the Dolphins in 1983 and immediately changed what a quarterback could look like. Wearing number 13, he went on to win the NFL MVP award in 1984 and broke numerous league passing records that held until the late 2000s. His career statistics, carved into his Ring of Honor plaque at Hard Rock Stadium, tell the story in numbers: 8,358 attempts, 4,967 completions, 61,361 passing yards, and 420 touchdown passes. Marino led Miami to five division titles, ten playoff appearances, and one Super Bowl berth, though that appearance in Super Bowl XIX ended in a loss. He won the Walter Payton Man of the Year Award in 1998, and the NFL Comeback Player of the Year Award in 1994 after returning from a serious injury. His final game as a professional came in a 62-7 playoff blowout against the Jacksonville Jaguars in January 2000, a loss so lopsided it was difficult to process for a player of his stature. His number 13 was retired on the 17th of September, 2000, during halftime of a Sunday Night Football game at Miami's stadium.

• 5. Rivalries That Shaped the Franchise

  ›

  The Dolphins went 20-0 against the Buffalo Bills in the 1970s, which says something about the power gap in the AFC East during that decade. The rivalry reversed in the 1980s and 1990s as Jim Kelly emerged as the Bills' starting quarterback, and Buffalo dominated their four playoff matchups against Miami during that stretch. The Patriots became an even deeper problem once Tom Brady arrived. New England won 16 of 17 division titles between 2003 and 2019, with Miami claiming the only non-Brady division title during that span, in a year when Brady missed games due to injury. One notable exception was a 2008 regular-season game in which the Dolphins upset New England on the road using a formation known as the Wildcat offense, handing the Patriots their first regular-season loss since the 10th of December, 2006, a loss that had also come at the hands of Miami. The New York Jets rivalry runs deep for a different reason: the influx of New York transplants to South Florida has kept tensions high on both sides. That series included Dan Marino's famous fake spike, former Jets quarterback Chad Pennington signing with Miami and leading the Dolphins to a division title, and a 1982 AFC Championship game that Miami won to advance to Super Bowl XVII. As of the 2024 season, the Dolphins hold all-time series leads over the Patriots at 64-55, the Bills at 62-60-1, and the Jets at 61-57-1.

• 6. Life After the Dynasty

  ›

  Jimmy Johnson replaced Shula before the 1996 season and managed back-to-back playoff appearances, but his tenure ended after Marino's final season. A parade of head coaches followed: Dave Wannstedt, Nick Saban, Cam Cameron, Tony Sparano, Joe Philbin, Adam Gase, Brian Flores, and Mike McDaniel. None of them built anything that lasted. Wannstedt brought the team an AFC East title in 2000 and a playoff win, but the team faded after that. Saban left for the University of Alabama after two seasons. Cameron's 2007 team went 1-15, the worst record in franchise history. The most recent division title came under Sparano in 2008, a year Miami made a ten-game improvement over 2007 and still couldn't advance past the first playoff round. Tua Tagovailoa, drafted out of Alabama in the first round of the 2020 NFL draft, became the quarterback of the future, and the team made the playoffs in 2022 and 2023 under Mike McDaniel. Both runs ended in the Wild Card Round. In December 2024, owner Stephen M. Ross sold 13 percent of the franchise at a valuation of $8.1 billion, with ten percent going to the investment group Ares Management, making Miami one of the first NFL teams to bring in outside private equity investors. Jeff Hafley was hired as head coach on the 19th of January, 2026, becoming the 15th head coach in franchise history.

• 7. Home, Identity, and Legacy

  ›

  The Dolphins originally played at the Orange Bowl in Miami, where a live dolphin named Flipper spent some seasons in a water tank in the open east end of the stadium, jumping to celebrate scores before being removed after 1968 to save costs, and again in the 1970s due to stress. The franchise moved after the 1986 season to what is now Hard Rock Stadium in Miami Gardens, a suburb of Miami about fifteen miles north of downtown. The venue went through a series of naming rights deals beginning in 1996 before landing on its current name in August 2016. A renovation costing more than $400 million was completed for the 2015-2016 season; every seat was replaced, lower-level seats were moved closer to the field, and the stadium shed roughly 10,000 seats in the process. The team's colors were originally aqua and coral, with coral chosen partly to honor the Miami Seahawks and the coral reefs of Biscayne Bay. The original logo showed a sunburst with a leaping dolphin wearing a football helmet. That look lasted until 2012. A new logo unveiled before the 2013 NFL draft replaced the helmeted dolphin with a stylized silhouette and brought navy into the color scheme for the first time. The Dolphins have thirteen players and coaches enshrined in the Pro Football Hall of Fame who spent the majority of their careers with the franchise, including Don Shula, Dan Marino, Bob Griese, Larry Csonka, and linebacker Zach Thomas, who was inducted in 2023.
