The Miami Dolphins have struggled in the NFL, often cited for their need to change the team's culture. Veteran linebacker Bradley Chubb expressed skepticism regarding last year's commitment to this change, asserting that the team was not fully dedicated to its goals. He pointed out that while there were intentions to improve, the collective effort was lacking, leading to disappointing seasons. However, he believes that this year, the team is more focused and determined to embrace necessary changes, though it remains uncertain how it will all unfold.
