Top 10 interior offensive linemen in the final 2025 On300 rankings

With February National Signing Day set for this Wednesday, the 2025 recruiting cycle is officially coming to a close. On3 has updated its player rankings for the final time.

Looking at the interior offensive linemen group, 31 prospects finish the cycle as a blue-chipper. Those trench monsters signed with 23 different college programs.

LSU and Texas A&M each signed three blue-chip interior O-linemen, while Alabama, Georgia, Georgia Tech and Oregon each inked a pair.

Below are the top 10 interior offensive linemen in the 2025 On300:

1. Michael Carroll — Alabama

School: Bradenton (Fla.) IMG Academy
On300 Ranking: No. 11 NATL.

Scouting Summary: “Large-framed offensive line prospect with dynamic run blocking ability and a physical edge to his game. Measured in at 6-foot-6, 315 pounds with 33-inch arms and massive 11-inch hands prior to his senior season. Emerged as the top interior offensive line prospect in the cycle as a junior and cemented that status as a senior. Has added good size and has a well-proportioned build. Lines up as an offensive guard and defensive lineman for his original high school, prior to transferring to IMG Academy as a senior. A high level functional mover. Highly dangerous as a puller when working to the second level. Blows up linebackers on contact. Uses his large hands and grip strength to manipulate defenders at the point of attack. Plays with a level of nastiness and seeks out contact. Works to finish blocks.

…Has a strong base, allowing for the ability to anchor in pass pro. Flashes his athleticism and plays with a high effort level on defense, tracking plays down from the back side. Shows his competitive nature in the camp setting and does not back down from matchups with top prospects. Plays in a run heavy offense and will need to continue developing as a pass blocker, but has the traits to improve there with more work. Has athletic pedigree with both parents – father played football at Penn State and mother played basketball at Michigan State – being former Division 1 athletes. Likely projects along the interior long-term but has the potential to feasibly line up at multiple spots on the college level. Size, athleticism, and competitiveness point to a high ceiling at the position.”

2. Carius Curne — LSU

School: Marion (Ark.)
On300 Ranking: No. 28 NATL.

Scouting Summary: “Freakish athlete along the offensive line. Measured in at 6-foot-4, 320 pounds with 33.5-inch arms and 9.5-inch hands prior to his senior season. Carries his weight well, looking like a much lighter player to the eye. Registers as an elite athlete in the combine setting, running a 4.8 second 40-yard dash and posting an eye-popping 4.3 second short shuttle at college camps prior to his junior season. Lines up as a two-way standout at his high school, playing left tackle and along the defensive line. Shows rare movement skills with twitch that immediately stands out. Moves at a different speed than most top offensive linemen. Excellent when working to the second level. Able to reach all the way to cornerbacks in blocking perimeter passes. Outstanding when asked to pull. Good at the point of attack. Keeps his feet moving once engaged and creates a big-time push.

…Projects as a high-end and potentially elite run blocker. Also flashes his elite athleticism as a defensive lineman. Would be a blue-chip prospect on that side of the ball, as well. Runs down plays from sideline to sideline. Older for the cycle, turning 19 years-old in December of his senior year. Will need to add polish as a pass protector, but has the lateral agility to develop well in that regard. Needs a runway to get a push at times, rather than simply generating pop off of the snap. Has the positional flexibility to potentially play all five spots on the offensive line. Possesses high-end potential in college football and beyond due to his phenomenal athleticism.”

3. Jaylen Gilchrist — Maryland

School: Virginia Beach (Va.) Salem
On300 Ranking: No. 79 NATL.

About Gilchrist: On3’s No. 1 player in Virginia this cycle. Committed to Maryland on Aug. 3, choosing Mike Locksley and the Terrapins over the likes of South Carolina and Georgia. The highest-ranked signee in Maryland’s 2025 class, per the On300. Headlines the Terps’ class alongside four-star quarterback Malik Washington. Was a part of a Salem High program that finished with a 10-2 record in 2024. One of the highest-ranked prospects to ever come out of the school.

4. Devin Harper — Ole Miss

School: Shreveport (La.) Calvary Baptist Academy
On300 Ranking: No. 85 NATL.

Scout’s Take: “For starters, Devin Harper is extremely physical and playing at a high level as a senior. When you watch his film you see a violent, explosive run blocker. He has plus length, particularly for a guard. Arms over 34″ and a ton of pop in contact. Strong film as a second level blocker, strong in gap scheme and a weapon in the run game. When you look at what he brings to the table physically, his mentality and play standpoint, there’s a lot to like. One of the better prospects in this cycle. His move up was certainly merited. I would project him as a multi-year starter. The type of lineman you want in the trenches in the SEC.”

5. Solomon Thomas — LSU

School: Jacksonville Raines
On300 Ranking: No. 127 NATL.

Scouting Summary: “Big-bodied, physical offensive lineman with versatility and one of the higher floors in what is a loaded cycle at the position. Measured in at around 6-foot-3.5, 315 pounds prior to his senior season. Touts elite length with 35.75-inch arms. Has a barrel-chested build with solid weight distribution. Lines up at tackle for his high school but likely has the highest upside as a guard long-term. Very stout at the point of attack. Plays with a strong base and has pop in his hands on contact. Detonates defensive linemen and linebackers with his punch. Plays with a physical edge and works to finish blocks. Has good technical ability in pass protection. Held up well in a 1-on-1 matchup against 2024 five-star defensive lineman LJ McCray as a junior. A solid, not overwhelming athlete. Can continue to improve his lateral agility and reactive quickness. Has the skill level to potentially get on the field early in his college career given his strength and battle tested resume.”

6. Nelson McGuire — Texas A&M

School: Midlothian (Texas)
On300 Ranking: No. 138 NATL.

About McGuire: Committed to Mike Elko and Texas A&M on Oct. 7, choosing them over the likes of Auburn, Clemson and Vanderbilt. Checks in at 6-foot-4.5 and 320 pounds. One of a whopping six offensive linemen signees in A&M’s 2025 class. The second highest-ranked of the bunch, behind just five-star offensive tackle Lamont Rogers. Won 10 games as a senior on Midlothian High. Also a top-25 player in the state of Texas, per the On300.

7. Juan Gaston — Georgia

School: Atlanta Westlake
On300 Ranking: No. 149 NATL,.

Scout’s Take: “Juan Gaston was one of the more pleasant surprises among 2025 prospects at the Under Armour All-America Game. At 6-foot-8 and over 380 pounds, Gaston is an absolute behemoth. He used his massive frame to swallow up defenders at the point of attack. In addition to the eye-popping size, Gaston flashed encouraging short-area quickness and quality bend for such a large player. He was a standout in 1-on-1’s throughout the week. Gaston will certainly need to trim down once he arrives in Athens and the lack of ideal arm length showed up some when he was lined up at tackle during the game itself. With that said, it was a positive showing for the Georgia signee, who provides an instant infusion of size and some positional versatility to the Bulldogs’ offensive line group.”

8. Isaac Sowells Jr. — NC State

School: Louisville Male
On300 Ranking: No. 162 NATL.

Scout’s Take: “Isaac Sowells Jr. was the definition of rock solid on the interior of the offensive line at the Navy All-American Bowl. The NC State pledge worked at center for the East team. We can’t recall seeing him lose a rep all week in San Antonio. Sowells continually stoned defensive linemen at the point of attack, highlighted by great showings in 1-on-1’s during practice. While he’s just around 6-foot-2, Sowells has compensatory length with very long arms and big hands. He is a functional mover with great ankle flexion and has impressive core and grip strength. The On300 prospect looks to be a steal for NC State. We wouldn’t be surprised to see him get on the field sooner rather than later in Raleigh.”

9. Danilo Guberinich — Texas Tech

School: Detroit Catholic Central
On300 Ranking: No. 188 NATL.

About Guberinich: One of the biggest risers in the final 2025 On300 rankings update. One of two Texas Tech signees in the final On300, alongside wide receiver Michael Dever. Committed to the Red Raiders on Nov. 21 while also holding offers from Vanderbilt and numerous mid-major programs. Checking in at 6-foot-5 and 285 pounds. One of six offensive lineman signees in Joey McGuire’s 2025 class. A key member of Detroit Catholic Central’s 2024 team that finished 12-1, ranking as the No. 2 team in the state, per the On3 Composite.

10. Josh Petty — Georgia Tech

School: Roswell (Ga.) Fellowship Christian
On300 Ranking: No. 192 NATL.

Scouting Summary: “Athletic, physical offensive lineman with positional versatility. Measured in at 6-foot-4, 255 pounds with 33-inch arms prior to his senior season. Two-way standout working at offensive tackle and defensive end for his high school. Shows high-end movement skills. Easily works to the second level. Light on his feet and moves with fluidity. Operates with a high level of conditioning playing on both sides of the ball. Good enough of an athlete to play on defense in college, though his upside is highest on the offensive line. Plays with a high effort level and physicality. Works to finish blocks with authority, driving defensive linemen to the sideline at times. Shows strong flexibility and core strength, coming off the ball low and firing through his hips. More advanced as a run blocker than pass protector at this time, but has the athletic ability to pass block at a high level with further development. A strong wrestler, finishing as a state champion and state runner-up in back-to-back years. Also threw the shot put with a personal best of 40-8.5 feet as a sophomore. Faces a lower classification of competition at the high school level.”
