College football’s 20 best offensive linemen of 2025

Lee Corso calls them the big uglies because they use their huge frames to maul defenders at the point of attack.

Although their hard work doesn’t show up on stat sheets, they make a tremendous impact on games. Communication is key for offensive linemen. However, false starts and bad snaps are unacceptable. Everything starts up front, and these 20 players will be valuable assets for their respective teams this upcoming season.

20. PJ Williams, Tackle, SMU: The former four-star prospect started all 14 games for the Mustangs last season, and helped them clinch a spot in the ACC Championship Game, and the Playoffs. Williams is a monster on the edge, standing six-foot-five, and weighing 317 pounds. He did a great job protecting quarterback Kevin Jennings’ blind side from his right tackle position. SMU finished fourth in the ACC, and 24th nationally in sacks allowed. Not to mention the Mustangs ranked 27th in the FBS in total offense. Williams capped off 2024 with third-team, All-ACC honors. The Texas native has experience too, with four starts at left tackle in 2023. Williams played for Texas A&M in 2022.

19. Earnest Greene, Tackle, Georgia: The Los Angeles native appeared in 11 games, and made nine starts for the SEC Champs last season. Greene also started all 14 games at left tackle in 2023. He knows how to maul defenders off the edge, and is an animal to deal with for would-be blitzers and defensive ends. With Dylan Fairchild and Tate Ratledge off to the NFL, Greene will be anchoring the big boys up front for Georgia. He’ll be facing some elite rushers across the conference this fall, but if Greene can play up to his potential, the 21-year old will have an All-SEC caliber campaign. Greene is currently wearing a club on his hand, after suffering a dislocated finger a week ago in practice.

18. Logan Parr, Guard, SMU: The Texas native is the Mustangs’ most-experienced offensive lineman. Parr started 13 games, which were mostly at left guard in 2024. He earned third-team, All-ACC honors for his heroics in the trenches. Parr started 13 games at left guard in 2023, and finished with first-team, All-AAC honors. Not to mention Parr spent three seasons at Texas, where he appeared in 16 games during that span. The former four-star prospect also takes care of business in the classroom, earning Academic All-AAC and All-ACC over the past two seasons. With Parr lined up alongside Williams again, SMU should have one of the best offensive lines in the ACC this fall.

17. Brian Parker, Tackle, Duke: The 21-year old started all 13 games for the Blue Devils last season. Parker protected Maalik Murphy’s blind side, as he passed for 26 touchdowns, which ranked fourth in the ACC. Not to mention Parker is a versatile lineman, who excels at left and right tackle. Parker helped Duke finish second in the league, and eighth in the FBS in sacks allowed. The Cincinnati native also ended 2024 with second-team, All-ACC honors. Parker is very experienced, and even started seven games in 2023. The former three-star prospect does stellar work in the classroom too, and is a two-time Academic All-ACC performer. He’ll anchor the Blue Devils’ offensive line.

16. Walker Parks, Tackle, Clemson: The former four-star prospect has four seasons worth of starting experience with the Tigers, and is a two-time, ACC Champion. Parks has been at Clemson since 2020, and is an animal in the trenches. He started all 14 games for the ACC Champs in 2024, protected Cade Klubnik’s blind side, as he passed for 36 touchdowns. Parks also started 13 games in 2021, 13 in 2022, and two in 2023. The Kentucky native ended last year with third-team, All-ACC honors. Parks is also very intelligent, considering he’s a three-time, Academic All-ACC performer. Having Parks and Blake Miller on both sides of the edge again, means pancakes are coming on the gridiron.

15. Sam Hecht, Center, Kansas State: Although he had no stars behind his name out of high school, the Kansas native has blossomed into an elite offensive lineman. Hecht had a breakout season in 2024, in which he filled Cooper Bebee’s shoes, started all 13 games at center, and played a team-high, 840 offensive snaps. He helped the Wildcats finish second in the Big 12, and 10th nationally in sacks allowed. Kansas State also led the conference, and ranked 11th in the FBS in rushing offense. Hecht earned second-team, All-Big 12 honors for his heroics, and academics. The six-foot-four, 287-pounder even helped Avery Johnson break the school’s single-season record for touchdown passes.

14. J.C. Davis, Tackle, Illinois: The Californian started all 13 games at left tackle for the Fighting Illini last season, and protected Luke Altmyer’s blind side. Davis is a six-foot-five, 320-pound monster, who ended his campaign with third-team, All-Big Ten honors. He is also very experienced in the trenches, with 12 starts at New Mexico in 2022, and another 12 in 2023. Davis’ protection is helping Altmyer blossom into one of the best returning quarterbacks in the Big Ten. The former two-star prospect has come a long way in his journey, and it appears the best is yet to come. Davis will be anchoring the big boys up front again this fall, so opposing defenders need to get ready to face a huge brick wall.

13. Omar Aigbedion, Guard, Baylor: The former two-star prospect started all 13 games at right guard for the Bears last season. Aigbedion helped the Bears finish seventh in the Big 12, and 36th nationally in sacks allowed. In return quarterback Sawyer Robertson was able to pass for 28 touchdowns, which tied for 14th in the FBS. Baylor also averaged 178.7 rushing yards per game. Aigbedion even capped off 2024 with second-team, All-Big 12 honors. He made a lot of noise at the FCS level too. The Texas native started 26 games over a two-year period at Montana State, and earned second-team, All-Big Sky honors in 2023. His experience, production and leadership will go a long way.

12. DJ Campbell, Guard Texas: The former five-star prospect has played in 37 games with the Longhorns, and started 30 over the past two seasons. Campbell started all 16 games at right guard in 2024, and helped Texas’ offensive line become finalists for the Joe Moore Award. He started all 14 games in 2023, and was a Big 12 champion. Last year he helped Texas running back Tre Wisner eclipse 1,000-yards on the ground. Campbell transitioned fine to the physical style of play in the SEC, and his experience will be vital for the big boys up front protecting Arch Manning this fall. The 21-year old will likely have a bigger role along the interior with Outland Trophy winner Kelvin Banks off to the NFL.

11. Gennings Dunker, Tackle, Iowa: The Illinois native started 11 games at right tackle for the Hawkeyes last year. Dunker was a big reason why Iowa’s offensive line were semifinalists for the Joe Moore Award. He even capped off his campaign with second-team, All-Big Ten honors. After all, he helped Kaleb Johnson rush for 1,537 yards, and a school single-season record, 21 touchdowns. Dunker started 13 games in 2023, and earned Honorable Mention All-Big Ten, and won the Team Hustle Award. The former three-star prospect also takes care of business in the classroom, and is an Academic All-Big Ten performer. Dunker playing alongside Logan Jones again will wreak havoc on opposing defenses. 

10. Olaivavega Ioane, Guard, Penn State: The former three-star prospect started all 16 games at left guard for Penn State last season. Ioane helped the Nittany Lions finish first in the Big Ten, and 17th in the FBS in rushing offense. Not to mention he paved the way for Penn State to produce two 1,000-yard rushers in the same season. Ioane dominated in the trenches from the interior, and earned second-team, All-Big Ten honors. The six-foot-four, 334-pounder also started five games in 2023. He’ll anchor the big boys up front again, and there’s no reason why the Nittany Lions can’t lead the conference in rushing again, and make another deep Playoff run with Ioane on the line.

9. Keylan Rutledge, Guard, Georgia Tech: The Georgia native is coming off an impressive campaign with the Yellow Jackets, and ended it with first-team, All-ACC honors. Rutledge gave great protection from the interior, and helped Georgia Tech finish first in the ACC, and third in the FBS in sacks allowed. He also paved the way for the Yellow Jackets to average 187 rush yards per game, which ranked 32nd nationally. The six-foot-four, 310-pounder paved the way for Georgia Tech to have a balanced attack, and it finished 35th in the FBS in total offense. Rutledge has a boatload of experience too, after starting 17 games over a two-year period at Middle Tennessee State from 2022-23.

8. Emmanuel Pregnon, Guard, Oregon: The former two-star prospect began his career at Wyoming, where he started 11 games at left guard in 2022. Pregnon transferred to USC the following season, where he started 12 games in 2023. Last year he started all 13 games for the Trojans, and didn’t allow a sack on a jaw-dropping, 882 snaps. Not to mention Pregnon capped off his last season at USC with second-team, All-Big Ten honors. The Denver native brings valuable experience and leadership to the reigning Big Ten champs. With Ajani Cornelius, and All-Big Ten performer Josh Conerly off to the NFL, look for Pregnon to make an immediate impact up front for Oregon this fall.

7. Bryce Foster, Center, Kansas: The former four-star prospect is one of the most-experienced offensive linemen in the country. Foster began his career in the Almighty SEC at Texas A&M, where he started 12 games in 2021. The following year Foster started four games before he suffered a season-ending injury. He bounced back tremendously, and started 12 games at center for the Aggies in 2023. Foster transferred to Kansas, and made an instant impact. So much so, that the Texas native started all 12 games, and helped the Jayhawks finish 13th nationally in rushing offense. Foster also contributed to Kansas leading the conference in sacks allowed, and earned second-team All-Big 12 honors.

6. Kadyn Proctor, Tackle, Alabama: The former five-star prospect missed the first two games of 2024 with a shoulder injury, but started the final 10 of the regular season for the Crimson Tide. Proctor is an immovable mountain, standing six-foot-seven, and weighting 360 pounds. He has great hand placement, and low center of gravity for a player his size. Proctor even capped off last season with second-team, All-SEC honors. The Iowa native started 13 games at left tackle for Alabama in 2023. Now he’s a veteran, and will anchor the unit up front. Proctor is currently sidelined with an injury in spring practice, but once he returns to the lineup, he’ll be a force to be reckoned with.

5. Blake Miller, Tackle, Clemson: The 21-year old is as mean as they come, and started all 14 games for the ACC Champs last season. Miller played a jaw-dropping, 944 snaps from scrimmage, which ranked second on the Tigers. He protected Cade Klubnik’s blind side, and the quarterback threw for 36 touchdowns. The former four-star prospect even capped off the year with first-team, All-ACC honors. Miller made 13 starts, played 960 offensive snaps, and earned third-team, All-ACC in 2023. The two-time, ACC Champion also started 14 games in 2022 as a true freshman, which included 989 offensive snaps. Miller is consistent, tough, durable, and always sets the tone up front for Clemson.

4. Logan Jones, Center, Iowa: The 23-year old started 12 games at center in 2024, and helped the Hawkeyes finish second in the Big Ten, and 24th nationally in rushing offense. Jones is versatile, a bonafide leader, and has a ton of experience. He even played some defensive end early in his career. Jones also earned first-team, All-Big Ten honors for his heroics up front last season. The Council Bluffs native started 13 games in 2023, and ended that year with third-team, All-Big Ten honors. Not to mention Jones made 13 starts in 2022. He’s a natural at opening up gaping holes, always plays with intensity, and brings credibility to Iowa’s offense. Now Jones is due for an All-American campaign.

3. Paolo Gennarelli, Guard, Army: The former three-star prospect had a breakout campaign, and led the way for the nation’s top rushing attack last season. Army averaged a jaw-dropping, 300.5 rushing yards per game, and Gennarelli was a man among boys in the trenches. He started 10 games at right guard, and one at right tackle in 2024, which displayed his versatility on the edge and along the interior. Although the Knights didn’t throw the ball often, Gennarelli helped protect the quarterback on passes, and the team finished second in the FBS in sacks allowed. The Illinois native made such an impact that he capped off the year with third-team, AP All-America honors.

2. Spencer Fano, Tackle, Utah: The former four-star prospect has been a force up front for the Utes over the past two seasons. Fano has been a starter ever since he stepped on campus, and shined on both sides of the edge. He started at right tackle in all 12 games in 2024, and finished the year with first-team, All-Big 12 honors. Fano also earned Academic All-Big 12, and second-team, AP All-America honors. The Utah native had an impressive freshman campaign in 2023, and made a start in all 13 games, including 11 at left tackle. Not to mention he was one of two freshmen to start at the beginning of that season for the Utes. Fano will be an immovable object in the Big 12 again, and maul defenders.

1. Jake Slaughter, Center, Florida: The 22-year old led the Gators offensive line with 800 snaps last season. Not only was Slaughter a team captain, but he also finished the year with first-team, AP All-SEC, and All-America honors. The former three-star prospect started eight games at center for Florida in 2023. Although Slaughter showcased his skills on the gridiron, he also handled his business in the classroom and made the SEC Academic Honor Roll three times. The Gators appear to be trending up on offense with DJ Lagway at quarterback. Slaughter will be responsible for keeping him upright. Regardless, the Florida native’s skills are unique, and makes him a terror to deal with up front.
