STM Take

2024 Pro Bowl plus the 6th overall draft slot plus the multi-team journeyman path puts Williams in the small group of edge-flex defenders with Pro Bowl ceilings across multiple defensive schemes. The USC 2014 Pac-12 DPOY plus 11 years of NFL development gives him real veteran market value. The 2026 question is whether Williams holds tier 4 territory at age 31 or whether the structural age-related decline reasserts.

Williams came out of USC as the New York Jets' 1st-round pick (6th overall) in 2015 after winning the 2014 Pac-12 Defensive Player of the Year. He was traded to the New York Giants in 2019, then traded to the Seattle Seahawks at the 2023 trade deadline. He made the 2024 Pro Bowl in his first full Seahawks season. His STTM career runs tier 7 (#50) in 2018, tier 8 (#72) in 2019, and tier 5 (#33) in 2025.

Strengths

2024 Pro Bowl plus the 6th overall draft slot plus 11 years of NFL survival across three systems gives him real veteran Pro Bowl résumé.
Multi-team experience plus positional flexibility (EDGE and IDL) gives him real veteran market value across schemes.

Concerns

Career STTM history has been sparse with multiple gap years in EDGE rankings, complicating the multi-year trajectory analysis.
Age 31 plus 11 years of pass-rush wear puts the structural late-career decline question on every 2026 projection.

What to watch: Whether Williams earns his second Pro Bowl in 2026 plus holds tier 4 or better, the threshold for confirming the 2024 Pro Bowl ceiling holds.
