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.

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
Wants to finish career in Miami
Sieler indicated earlier this offseason that he wants to spend the rest of his career with the Dolphins, Marcel Louis-Jacques of ESPN.com reports.
ANALYSIS
The 30-year-old defensive tackle will see a three-year, $64 million contract extension kick in for 2027, which potentially makes him a prime candidate to be moved before his salary and cap hit go up, but Sieler isn't looking to leave the rebuilding club. After back-to-back seasons with exactly 10.0 sacks, Sieler saw his pass rush production drop to 5.5 sacks over 17 games in 2025.
