Production dips in 2025
Sieler made 47 tackles (29 solo), including 5.5 sacks, across 17 regular-season games in 2025. He also had one pass defensed and one fumble recovery.
ANALYSIS
Sieler played two more games in 2025 than he did in 2024, but he nonetheless finished with just more than half the 10.0 sack total he had managed in each of Miami's prior seasons. The 30-year-old defensive tackle is under contract with the Dolphins through 2029, but the team will have a potential "out" in his contract after the 2026 campaign, making it potentially crucial for Sieler to bounce back to his usual production level next season.

2020
Sieler spent the first several seasons of his career as a strong run defender but struggled to make a significant impact as a pass rusher. However, the Dolphins have shifted his primary role to playing the B-gap (between the guard and tackle) in the last two seasons. The result has been more well-rounded production, as he's combined to post 20 sacks (10 each year) across the last two campaigns. That has been backed by 41 quarterback hits, suggesting that his new level of production is hardly a fluke. Entering his age-29 season, there's no reason to believe Sieler's production or role will change in 2025, making him among the best interior pass rushers in the league and a valuable IDP option.

Latest Fantasy Rumors
Won't hold out for extension
Sieler doesn't intend to hold out from training camp as he seeks a contract extension from the Dolphins, Barry Jackson of the Miami Herald reports.
ANALYSIS
The 29-year-old edge rusher has recorded back-to-back seasons with 10.0 sacks for Miami, and while agent Drew Rosenhaus confirmed that Sieler would attend camp, he declined to say if his agent would fully participate in practice and workouts without an extension. Sieler has two years remaining on his current deal with a total base salary of just $14.88 million across both seasons, well below his market value.
