What happened: PFF set a 20-snap minimum; Harold Perkins Jr. ranked second at 81.7 and Jack Kelly third at 81.4. Josiah Trotter (80.5) and Tahj Chambers (80.4) completed the top five.
Why it matters: The ranking provides an early performance marker as clubs set regular-season linebacker rotations. Limited preseason samples leave those roles open to change as snap counts rise.
By the numbers: Reese finished 6.5 points ahead of Perkins, 6.8 ahead of Kelly, 7.7 ahead of Trotter and 7.8 ahead of Chambers. Perkins and Kelly were separated by 0.3 points; Trotter and Chambers by 0.1.
What to watch: Regular-season snap shares will show whether the five rookies convert their preseason marks into sustained roles.
