Miami Dolphins defensive coordinator Sean Duggan said communication, confidence and connected play remain central to the defense’s preparation for Sunday’s game against the 49ers. Duggan addressed the unit’s development, personnel competition and matchup challenges during a Sept. 17 media availability. The Miami Dolphins published the transcript Sept. 18.
Duggan declined to discuss whether Chop Robinson sustained an injury in practice and directed injury-related questions to Coach Hafley. He said the defense prepares every player because football is unpredictable and different personnel situations can arise. “I think your job as a coach is to prepare everybody, right? I mean, you never know what could happen, it’s an unpredictable game,” Duggan said.
Miami Dolphins Defense Emphasizes Collective Execution
Duggan said the defense was hesitant early in its previous game but improved as the game progressed. He wants the players to play with confidence while maintaining the fundamentals and physicality required by the defensive system. He said the unit can stop the run, rush the passer and affect throws, even when those contributions are not fully reflected in statistics.
Duggan said Kirk did a good job getting the ball out quickly, but he evaluates pressure by more than traditional statistics. Closing the pocket and affecting throws were areas he felt improved, particularly in the second half. He also said Malik and Ferrell were among the edge players the defense is preparing to contribute.
Playing together across position groups was another focus for Duggan. He said defensive tackles and ends must coordinate their rushes, linebackers must work off one another, and safeties must communicate in the secondary. “I think playing together regardless of positions I think it’s really, really important,” Duggan said.
Young Players Must Continue to Develop
Duggan said the team’s young defenders were initially uneasy but became more comfortable as the game continued. He saw communication improve on film, which helped the players anticipate plays and execute with greater confidence. The coordinator said the Dolphins will continue coaching those players while expecting them to prepare and grow.
“We’re never going to use youth as an excuse,” Duggan said. Chris Johnson was one of the young defensive backs discussed during the availability. Duggan said Johnson responded positively after Kirk Cousins targeted him and continued to show confidence in practice.
Duggan said a completed pass can involve different factors, including technique, leverage or the execution of a defensive call. He nevertheless praised Johnson’s response and said the rookie defensive back will continue to improve. The experience did not cause Johnson to lose confidence, according to Duggan.
Secondary Competition Remains Open
Duggan described Chris, Jason and JuJu as three starting-caliber players competing daily. He said the competition is ongoing rather than based on a fixed hierarchy. “I look at it as we have three starting caliber players and they’re going to compete every single day we’re out here, just like the rest of the guys on our defense,” Duggan said.
At safety, Duggan discussed Zayne and Michael starting while Dante rotates into the group. He said the usage is based partly on defensive packages and partly on timing or game-plan considerations. Certain players may be used for a particular call, series or situation.
Duggan also praised the communication between Coach Hafley, the defensive staff and the players during the previous game. He said the communication was strong and the operation was clean for the first game, while acknowledging that the staff still has room to improve its adjustments. “I thought for the first game it was pretty clean,” Duggan said.
Christian McCaffrey and 49ers Receivers Present Challenges
Duggan identified Christian McCaffrey as a major challenge for the Miami Dolphins defense. He highlighted McCaffrey’s vision, ability to stop and accelerate in the hole, shiftiness, physical running style and contact balance. McCaffrey’s receiving ability adds another responsibility because defenders must remain aware of his location whenever he has the ball.
“He’s just a guy when he gets the ball in his hands you got to be aware. You got to be aware where he is,” Duggan said. Duggan also discussed Mike Evans and Deebo Samuel as part of a physical 49ers receiving group. He said Miami must play aggressively while maintaining sound fundamentals.
Duggan said moving Evans around the formation makes defensive planning more difficult. A fixed alignment allows a defense to allocate resources more easily, while movement forces defenders to adjust their plans and communication. “When they move guys around it does make it challenging,” Duggan said.
FSB Take
The Miami Dolphins enter Sunday’s game against the 49ers with defensive communication and player development at the center of their preparation. Duggan’s comments showed that the unit is still refining how its young players function within larger groups while managing competition in the secondary. The defense also must prepare for personnel movement and multiple responsibilities from McCaffrey.
The key test will be whether Miami can carry its improved communication and second-half confidence into the matchup. The secondary rotation, coordination among the defensive units and preparation of every available edge player will remain important areas to watch. Duggan’s emphasis was clear: the Dolphins expect every defender to be ready and will not use youth as an excuse.
