Miami Dolphins got a B Contract Value Index out of the Zach Sieler signing because the guaranteed money matches the production tier. At 30 years old with eight seasons under his belt, Sieler delivered a solid 2025 season with 47 tackles and 5.5 sacks across 17 games—the kind of reliable, above-average interior production that justifies organizational confidence in an established veteran. His $21.3M AAV over three years positions him in the mid-tier range for defensive tackles, a fair market rate for a Pro Bowl-caliber run defender who remains genuinely invested in the franchise. The narrative around this deal transcends mere cap math: Sieler's public commitment to retire as a Dolphin, combined with the front office's recent wave of roster construction signings, frames him as a stabilizing anchor in what is clearly a rebuilding effort. The CVI grade reflects the alignment between what Miami is paying and what he's delivering—neither a steal nor an overpay, but a sensible long-term anchor deal for a high-character veteran. The upside risk is modest given his age and established role; the downside is equally contained, making this a low-drama contract in a transitional period where Miami appears to be building incrementally rather than chasing immediate impact.
Other same-position deals the Contract Value Index also places in the B band — a quick read on where Zach's contract sits relative to comparable money.
Zach Sieler delivers production that earns a A performance grade against DT comps. At 30 years old and eight seasons into his career, the established veteran has proven he remains a high-end interior defender in the trenches — his 2025 season of 47 tackles and 5.5 sacks across 17 games demonstrates both durability and consistent disruptive ability. The tackle total stands as his primary strength, reflecting his role as a reliable anchor in Miami's front-seven, while his sack output, though respectable, sits slightly below elite interior-pass-rush thresholds for a top-tier lineman. Sieler's full-season availability is a genuine asset in a league where defensive line durability often determines scheme continuity, and his willingness to embrace the new coaching staff's direct communication style signals the kind of professional adaptability that sustains veteran production. The three-year, $64 million extension signals organizational confidence in his cornerstone status, and his public commitment to retire in Miami has generated tangible goodwill — yet that same investment now places heightened scrutiny on him to justify top-dollar compensation while the franchise navigates a transitional rebuild period. For a player entering the prime window of his thirties, Sieler remains a dependable, high-character fixture whose performance grade reflects sustained excellence, though the pressure to anchor a rebuilding roster adds meaningful stakes to his tenure.
Zach Sieler ranks 5th of 216 graded defensive tackles by performance. That slots Zach between Jeffery Simmons (A) just ahead and Ed Oliver (A) just behind.

Ed OliverBuffalo BillsMiami Dolphins fans and writers have settled into a B sentiment grade on Zach Sieler. The narrative around the 30-year-old defensive tackle has shifted decidedly positive in recent weeks, anchored by his three-year, $64 million contract extension and his public declaration that he wants to retire as a Dolphin—a loyalty statement that has resonated warmly in an era when such commitments are rare. Media coverage emphasizes his receptiveness to the new coaching staff's direct communication style and frames him as a high-character, dependable interior presence, which aligns neatly with his on-field production: the 2025 season marked 47 tackles and 5.5 sacks across 17 games, a solid, established-veteran profile that justifies organizational confidence. However, the sentiment does carry an undertone of pressure—some analysts have flagged that his prominent role in a rebuilding roster means he must now justify the front office's investment while Miami navigates a transitional period, adding scrutiny to his performance expectations. The recent wave of Dolphins signings (Aaron Brewer, Chris Johnson, Seydou Traore, and others across the defensive and offensive line) frames Sieler not as a relic of a failing regime, but as a stabilizing anchor in a reconstructed roster, which has bolstered his standing among fans and beat writers alike.
