STM Take
Tier 2 (#12) breakout in 2022 plus the Ferris State Division II 7th-round origin plus eight years of NFL survival puts Sieler in the rarest outlier-positive draft-slot-vs-outcome class at the interior defender position. The Dolphins anchor reps plus the multi-year mid-prime production give him real veteran value. The 2026 question is whether Sieler returns to tier 4 territory or whether the structural late-career decline reasserts.
Sieler came out of Ferris State (Division II) as the Baltimore Ravens' 7th-round pick (238th overall) in 2018 and has anchored the Miami Dolphins' interior since 2020. His STTM career runs tier 6 (#41) in 2019, tier 4 (#31) in 2021, tier 2 (#12) breakout in 2022, and tier 5 (#34) in 2025.
Strengths
- 2022 tier 2 (#12) STTM peak as a Ferris State Division II 7th-round pick puts him in the most outlier-positive draft-slot-vs-outcome class at the position.
- Eight years of NFL survival as a 238th overall pick gives him the rarest journeyman elite-peak résumé at the position.
Concerns
- 22-spot regression from tier 2 (#12) in 2022 to tier 5 (#34) in 2025 confirms the structural ceiling has compressed.
- Miami's broader defensive identity around the Tua Tagovailoa offensive instability puts continued Sieler production partly outside his control.
What to watch: Whether Sieler returns to tier 4 (top 30) in 2026, the threshold for confirming the structural ceiling can climb again.
