STM Take
Tier 8 (#65) to tier 1 (#8) in one year is a 57-spot jump for a 6th-round pick, putting McDuffie in the rarest outlier-positive class at the LB position. The Boston College ACC 6th-round origin plus the Packers' Jeff Hafley defensive scheme appears to be the catalyst. The 2026 question is whether McDuffie holds tier 3 or better across a full second starter season or whether the 2025 finish was a one-year context spike.
McDuffie came out of Boston College as the Green Bay Packers' 6th-round pick (220th overall) in 2021. He spent his first four years as developmental depth and rotational LB. His STTM career runs tier 8 (#65) in 2023, tier 8 (#65) in 2024, and tier 1 (#8) breakout in 2025, a 57-spot one-year jump.
Strengths
- 57-spot year-over-year jump from tier 8 (#65) to tier 1 (#8) as a 220th overall 6th-round pick puts him in the rarest outlier-positive class.
- Boston College ACC pedigree plus five years of Packers system experience gives him real developmental foundation.
Concerns
- Single tier 1 finish in an otherwise tier 8 STTM history puts the 2025 production on a small sample with significant downside risk.
- Green Bay's broader defensive identity around Jeff Hafley's first-year scheme puts continued McDuffie ceiling partly scheme-dependent.
What to watch: Whether McDuffie holds tier 3 or better across the full 2026 season, the threshold for confirming the 2025 breakout was structural rather than situational.
