Zach Frazier, the Pittsburgh Steelers center, has gained significant recognition as one of the NFL's top rookies early in the season. Ranked sixth overall by Pro Football Focus after Week 3, he boasts an impressive 76.8 grade, primarily due to his exceptional run-blocking skills.

Despite needing improvement in pass protection, with a 57.7 grade, Frazier's 78.5 run-blocking grade places him seventh among centers. Initially not expected to start due to an injury to Nate Herbig, Frazier has stepped up remarkably, solidifying his role on the team.
