Pocic’s return to the Pacific Northwest should not be a surprise, however. Excellent value aside, he has a profile that stands out from the shiny, glossier, centers that were also available in free agency. I’m specifically talking about arm length. At the 2017 combine, Pocic measured in with 33 1/8-inch arms.
That 33-inch mark seems to be rather important for Seattle. Since Mike Solari became line coach in 2018, the Seahawks have never taken an interior offensive lineman with arms shorter than 33 inches. In 2020, Damien Lewis' arms measured at 33 inches and in 2019, guard Phil Haynes measured in at 33 1/2 inches.
A sample size of two men, guards at that, isn’t enough proof. Instead, consider that previous long-term centers in Seattle had arms near that 33-inch mark. Justin Britt was 33 1/2 inches. Max Unger was 32 1/2 inches. Both of these players earned their role before Solari’s arrival. Solari’s history suggests length from his snapper is even more important.

By the way the arm length I found for Kyle Fuller is 32 7/8 inch. Arm length found for Brad Lundblade is 31 3/4 inch.
