The Big Ten conference, once known for its ground-and-pound style, has evolved into a pass-happy league, but it still produces top-tier interior offensive linemen. In the latest installment of Dane Brugler's 2027 NFL Draft Summer Scouting series, the focus shifts to guards and centers, with the Big Ten heavily represented among the top prospects.
While no player is considered a lock for the first round, several have the potential to become immediate NFL starters. The rankings include both draft-eligible underclassmen and seniors, with heights and weights provided by league sources.
Top Prospect: Kade Pieper, Iowa
Kade Pieper, a 6-foot-4, 298-pound Iowa product, ranks first among centers. Known for his run-game athleticism and relentless intensity, Pieper consistently displays fluid movement and a competitive edge. He excels at reaching the second level and finishing blocks, though his lack of ideal NFL size can be exposed against powerful defenders. Pieper moved from guard to center during spring practices, following in the footsteps of former Hawkeyes Tyler Linderbaum and Logan Jones. He earned All-Big Ten honors last season and is projected as a top-60 pick.
Second-Ranked: Greg Johnson, Minnesota
Minnesota's Greg Johnson (6-7, 327 pounds) stands out for his quick processing and strong anchor in pass protection. Despite his height, he uses leverage and balance effectively to maintain his base. Johnson has experience at all five offensive line positions, starting at center in 2024 and left guard in 2025. With verified size and 33-inch arms, he possesses the physical traits NFL teams covet. If he improves his hand placement consistency, Johnson could be one of the first interior linemen drafted.
Third-Ranked: Anthonie Knapp, Notre Dame
Notre Dame's Anthonie Knapp (6-4, 300 pounds) is praised for his nasty blocking demeanor and heavy hands. The Georgia native, who was an unheralded recruit, earned the starting left tackle job as a freshman in 2024. After 27 starts at tackle, he is expected to move to guard for the 2026 season, a transition that should benefit his game. Knapp's core strength and competitive toughness make him a candidate for the 2027 draft.
Other Notable Prospects
Ohio State's Austin Siereveld (6-5, 325 pounds) ranks fourth, lauded for his finishing mentality and versatility. He started at left tackle in 2025 but is better suited for guard, where he could become an All-American. Indiana's Carter Smith (6-5, 307 pounds) rounds out the top five, known for his balance and savvy. Despite average arm length, he projects well as an interior lineman and could compete for early NFL playing time.
The rankings also include a top 20 list of senior interior offensive line prospects, featuring Luke Montgomery (Ohio State), Alani Noa (USC), and Cayden Green (Missouri), among others. The top 10 draft-eligible underclassmen list includes Pieper, Knapp, Siereveld, and Evan Tengesdahl (Cincinnati).
