STM Take

Nine years as Colts' starting interior defender as an Albany State Division II 4th-round pick puts Stewart in the rare class of stable journeyman starters with structural top-40 ceiling. The Albany State HBCU pedigree plus the Colts' anchor role gives him real veteran value. The 2026 question is whether Stewart holds tier 5 or better at age 32 or whether the structural late-career decline reasserts.

Stewart came out of Albany State (Division II) as the Indianapolis Colts' 4th-round pick (144th overall) in 2017 and has anchored the Colts' interior across nine seasons. His STTM career runs tier 7 (#49) in 2021, tier 5 (#33) in 2022, tier 6 (#47) in 2023, tier 4 (#30) in 2024, and tier 5 (#36) in 2025.

Strengths

Nine years of NFL starter reps as an Albany State Division II 4th-round pick puts him in the rarest outlier-positive class at the position.
Career STTM range stable in the tier 4-7 band across five years confirms structural starter ceiling exists across multiple Colts coaching transitions.

Concerns

Career STTM range capped at tier 4 (#30) flags the realistic ceiling at top-30 IDL rather than Pro Bowl territory.
Age 32 plus nine years of nose tackle wear puts the structural late-career decline question on every 2026 projection.

What to watch: Whether Stewart holds tier 5 or better in 2026 at age 32, the threshold for confirming the stable starter ceiling continues.
