Imagine your favorite sports team is like a big company. On Tuesday, the Miami Dolphins made a major change at the very top—kind of like when a school gets a new principal after the same one has been there for 13 years.
Tom Garfinkel, who has been the team’s President and CEO since 2013, stepped down. In his place, owner Stephen Ross promoted Daniel Sillman to run football operations. This wasn’t totally out of the blue—Sillman was already the guy who helped hire the new General Manager (Jon-Eric Sullivan) and Head Coach (Jeff Hafley) this offseason.
Important Point: Think of Sillman as the new "Captain of the Ship" for all of Stephen Ross’s sports and entertainment businesses.
Sillman didn’t just get the Dolphins job. He was named CEO of a brand-new company called Ross Sports & Entertainment. This new umbrella group puts all of Ross’s major assets under one roof:
For the Dolphins specifically, these key people now report to him:
Don’t worry—Garfinkel isn’t disappearing. He’s just changing seats on the bus.
The team’s press release bragged (rightfully so!) about what Garfinkel built over 13 years:
| Achievement | Details |
|---|---|
| Revenue Growth | Increased annual revenues by over 400% |
| Sponsorship Deals | Secured $3+ billion in future guaranteed sponsorship income |
| Stadium Makeover | Led the $550 million private renovation of Hard Rock Stadium |
| Training Facility | Oversaw the $135 million Baptist Health Training Complex |
| Charity | Grew the Dolphins Cancer Challenge into the NFL’s largest fundraiser—$100+ million for cancer research |
| Big Events Brought to Miami | • Miami Grand Prix (F1) • Miami Open tennis • Super Bowl • 2 College Football National Championships • 7 matches in the 2026 World Cup (including the 3rd place game) |
"I love the Dolphins and the people here, but after 13 years it was just the right time for me to make this decision. The business has never been in a better place and the team of people we have here is second to none in sports. I want to thank the South Florida community and Dolphins fans for all of their support over the years and especially Steve Ross for the opportunity to be a part of this great organization. He is a visionary leader and a team owner who always strives to be best-in-class, and he provides his people all the trust and resources needed to be successful. I have every confidence in where this organization is headed on and off the field under Danny’s leadership, and I’m excited about the new challenges that will come moving forward."
Translation: "It’s time for a new chapter. I’m proud of what we built. The team is in great hands with Danny."
Sillman isn’t just the new CEO—he’s officially in the succession plan for Stephen Ross. That means if anything ever happens to the owner, Sillman is the designated next-in-line. This signals long-term stability.
Before, the Dolphins, the stadium, the F1 race, and the tennis tournament might have operated more separately. Now, one person (Sillman) oversees all of it. This could mean:
The guys making football decisions—Sullivan (GM), Hafley (Coach), Shore (Football Ops VP)—all keep their jobs. They just have a new boss. No panic needed.
| What Happened | What It Means |
|---|---|
| Tom Garfinkel stepped down after 13 years as President/CEO | He stays as Vice Chairman & F1 Managing Partner |
| Daniel Sillman promoted to CEO of football ops | He led the GM & Coach searches this offseason |
| New company formed: Ross Sports & Entertainment | All Ross sports assets now under one roof |
| Sillman is in the succession plan for owner Stephen Ross | Long-term stability signaled |
| Football leadership unchanged | Sullivan, Hafley, Shore stay in place |
No. He stepped down voluntarily after 13 years. His quote makes it clear it was his decision ("it was just the right time"). He’s staying with the organization in new roles.
Sillman has been working closely with ownership and ran the searches that brought in the new GM and Head Coach. Ross clearly trusts him and sees him as the future leader of his entire sports empire.
Not directly. The football decision-makers (GM, Coach, Football Ops VP) all remain in place. Sillman is their new boss, but the football structure is stable.
It’s a new holding company that puts the Dolphins, Hard Rock Stadium, Miami Grand Prix, Miami Open, and Precision Drive Club under one leadership team. Think of it like putting all your sports toys in one toy box with one label.
There’s zero indication of that. In fact, naming a successor (Sillman) suggests the opposite—Ross is planning for the long-term future of the franchise under his ownership family.
Final Thought: Change at the top after 13 years is a big deal, but all signs point to a smooth, planned transition. The football people stay, the business is booming, and the new guy already knows the playbook. Dolphins fans should feel optimistic about the stability of the organization.
