Tom Garfinkel stepped down from day-to-day leadership of the Miami Dolphins on Tuesday after 13 years at the top of the organization, and Stephen Ross named Daniel Sillman to the top spot of football operations. Garfinkel is not leaving the building entirely. He will remain vice chairman for the Dolphins and Hard Rock Stadium, and he will continue as managing partner for the Miami Grand Prix.
The move matters because it changes who is expected to steer the franchise’s daily decisions while keeping one of its longest-serving executives in a still-powerful role. Ross Sports & Entertainment puts the Dolphins, Hard Rock Stadium, the Miami Grand Prix, the Miami Open tennis tournament and the Precision Drive Club under one umbrella, which means the handoff sits inside a wider business structure rather than a simple football reshuffle.
Sillman is not new to the job’s demands. He led the team’s search this offseason for new general manager Jon-Eric Sullivan and new head coach Jeff Hafley, giving him a direct role in the football overhaul before the leadership change was announced. He was also named chief executive of Ross Sports & Entertainment, placing him in charge of the broader portfolio that now sits above the Dolphins operation.
That is where the change gets more complicated. Garfinkel is stepping away from day-to-day leadership, but he is still staying on as vice chairman for the Dolphins and Hard Rock Stadium, which means the title change does not amount to a full exit. On paper, Sillman now has the top football operations role, but Garfinkel remains tied to the stadium and the franchise’s ownership structure, leaving the practical split to be worked out in the ordinary flow of business rather than in a formal public handoff.
Garfinkel said it was the right time to make the decision after 13 years and thanked the South Florida community and Dolphins fans for their support. He pointed to the business as being in its best shape and said the group of people around the organization was second to none in sports, while adding that he had full confidence in what comes next under Danny’s leadership.
The departure closes one chapter for an executive whose run included more than 400 percent growth in annual revenues, more than $3 billion in future contractually obligated sponsorship income, the $550 million transformation of Hard Rock Stadium and the $135 million Baptist Health Training Complex. It also came after he helped grow the Dolphins Cancer Challenge into the NFL’s largest charitable fundraiser, generating more than $100 million for cancer research, while bringing the Miami Grand Prix for Formula 1 and the Miami Open to Hard Rock Stadium. The unresolved question now is not who is in charge on Tuesday; it is how much of the franchise’s day-to-day power will sit with Sillman while Garfinkel still holds the vice chairman role that keeps him close to the center of it all.
