STM Take

Tier 4 (#29) in 2024 with the Raiders to tier 8 (#69) in 2025 with the Dolphins is a 40-spot regression that confirms the structural ceiling is highly team-fit dependent. The Arizona State Pac-12 4th-round origin plus four years of NFL development give him basic journeyman veteran value. The 2026 question is whether Jones returns to tier 5-6 territory with Miami or whether the role compresses to swing depth.

Jones came out of Arizona State as the New England Patriots' 4th-round pick (121st overall) in 2022. He bounced through the Patriots and Raiders before signing with the Miami Dolphins in 2025. His STTM career runs tier 4 (#29) in 2024 with the Raiders to tier 8 (#69) in 2025 with the Dolphins.

Strengths

  • 2024 tier 4 (#29) Raiders STTM finish as a 121st overall 4th-round pick puts him above his draft-slot expectation.
  • Arizona State Pac-12 4th-round origin plus four years of NFL survival across three teams gives him real journeyman veteran value.

Concerns

  • 40-spot regression from tier 4 (#29) in 2024 to tier 8 (#69) in 2025 confirms the ceiling is highly team-fit and scheme dependent.
  • Miami's broader defensive identity around the Tua Tagovailoa offensive instability compresses the structural support around Jones.

What to watch: Whether Jones returns to tier 6 (top 50) in 2026 with the Dolphins, the threshold for confirming the 2024 ceiling can be recaptured.
