The Pittsburgh Steelers played their best game offensively of the season in Week 3 against the Los Angeles Chargers, and two rookie offensive linemen helped make an impact, keeping the pocket clean for Justin Fields in his best game of the season. OG Mason McCormick, who replaced Spencer Anderson and also came in on some tackle-eligible plays led all rookie offensive linemen with a 0% pressure rate, not allowing a single pressure on 13 pass-block snaps. Meanwhile, rookie C Zach Frazier had another impressive outing, finishing third among rookie linemen with a 2.9% pressure rate, allowing just one pressure in 35 pass-block snaps.
