Which centers and guards populate the list of the top interior offensive line (iOL) prospects in the 2024 NFL Draft cycle on our position rankings? Established veterans, versatile glue pieces, and ascending young players dot our early rankings, but two projected tackle-to-guard converts also have a strong case for the top spot.
Ranking the Top iOL in the 2024 NFL Draft
It’ll be a few years before we truly get a read on how good the 2023 NFL Draft’s interior offensive line class was. There were few guarantees across the class, but many tackle-to-guard converts, positionally flexible prospects, and players with notable transitions still to come.
Position switches are a constant caveat in the iOL discussion every draft cycle, but the 2024 class may have more prospects who are settled into guard or center designations. And with that clarity should come a heightened degree of security — at least for most of the group.
Here’s a look at how the 2024 NFL Draft iOL group looks right now and which prospects are in play for potential Round 1 capital.
10) Christian Mahogany, G, Boston College
On a broad scope, NFL teams love resilience. And Christian Mahogany’s story defines such a quality. Mahogany tore his ACL ahead of the 2022 season and missed his entire redshirt junior campaign but returned to be a first-team All-ACC performer in 2023.
At 6’3″ and 322 pounds, Mahogany is a verified road-grader in the run game with uncommon competitive toughness and tenacity. He’s as physical as they come as a finisher, and he has enough athleticism to work in space and accelerate into second-level defenders.
9) Isaiah Adams, G, Illinois
The Illinois Fighting Illini are slowly becoming reliable producers of NFL Draft talent on both the offensive and defensive sides of the ball. Illinois’ offensive line was one of the best composite units in college football in 2022.
Players like Julian Pearl, Alex Pihlstrom, and Alex Palczewski heavily contributed to that reputation, and so did left guard Isaiah Adams.
Both Adams and Pearl returned in 2023. Adams, in particular, might have the most exciting upside of the previously mentioned group when projecting to the NFL.
At 6’5″ and 315 pounds, the former JUCO transfer has a powerful frame and can generate immense force at contact. He routinely stays square in pass protection but also has the athleticism to match and block in space.
8) Tanor Bortolini, C/G, Wisconsin
After sending Joe Tippmann to the New York Jets in Round 2 of the 2023 NFL Draft, the Wisconsin Badgers have another center who could crack the early rounds in Tanor Bortolini.
The 6’4″, 314-pound Bortolini started 10 games for the Badgers in 2022, including six at left guard, two at right guard, and one at center. In 2023, he shifted to center full-time, providing stability at the fulcrum of the line.
Bortolini’s already-proven versatility is appealing, but even more so is his explosive athleticism, mauler mentality, and low-cut frame that makes him a legitimate power plant when driving and displacing defenders.
7) Christian Haynes, G, UConn
The UConn Huskies might make a triumphant return to the 2024 NFL Draft stage this coming cycle, and Christian Haynes is bound to lead that movement. The 6’2″, 313-pound guard started 37 straight games for the Huskies from 2019 to 2022 and returned as a central force for the unit in 2023.
In the trenches, the combination of strong natural leverage and proportional length is always a winning mix, and it’s something Haynes has. He can get under his opponents easily and has the combined explosive athleticism and frame density to generate eye-catching amounts of displacement energy.
6) Cooper Beebe, G, Kansas State
Had he declared for the 2023 NFL Draft, Cooper Beebe would have graded higher than Bills starter O’Cyrus Torrence on my board. He was a standout tackle in 2021, then moved to guard in 2022, where his traits translated seamlessly.
Beebe ultimately won Big 12 Offensive Lineman of the Year and returned to impose his will in 2023.
At 6’4″ and 332 pounds, Beebe has tremendous size, width, and mass as an interior blocker. He’s not an elite athlete, but Beebe’s mobile enough to get out in space as a pulling blocker, maximizing his opportunities with stellar angle awareness and football IQ. At contact, he has the strength, power, and length to torque his opponents into submission.
5) Sedrick Van Pran, C, Georgia
Sedrick Van Pran was the starting center for all 30 games of the Georgia Bulldogs’ back-to-back championship seasons. After redshirting in 2020, he took the starting role and ran with it. He entered 2023 as one of the best center prospects in the nation, and he still is.
Van Pran might’ve challenged Tippmann and John Michael Schmitz in the 2023 cycle. He doesn’t quite have the power Tippmann boasts, and Schmitz is a bit stronger and more refined.
Nevertheless, Van Pran has excellent natural leverage at 6’4″ and 310 pounds, and he’s one of the most explosive athletes you’ll see at the center spot. He moves off the line at a different pace, bringing a finishing brand of physicality through reps.
4) Zach Frazier, C, West Virginia
West Virginia’s Zach Frazier isn’t quite our top pure center prospect in the 2024 NFL Draft, but he’s still an NFL starter in waiting. The 6’3″, 310-pound Frazier was a four-time heavyweight wrestling champion in high school and similarly dominant in college.
At his size, Frazier has a well-built, low-cut frame with exceptional upper body mass and strength. He’s a nimble, flexible mover who can maintain discipline and leverage in space while plowing through and sealing off defenders, and his football IQ ties his game together.
3) Jackson Powers-Johnson, C, Oregon
The 2024 NFL Draft center class didn’t need Jackson Powers-Johnson to declare with Barton, Frazier, and Van Pran at the top. But you won’t see NFL teams complaining about the soon-to-be 21-year-old Rimington Award winner hitting the circuit. He’s already as good as they come.

At 6’3″ and 320 pounds, Powers-Johnson has stellar athleticism in space, combined with exceptional blocking leverage and power drive, steely physicality at contact, and awareness in both phases. He has the potential to lock down one NFL team’s center spot for a decade-plus while being a staple on the ground.
2) Troy Fautanu, G, Washington
The Washington Huskies had two respectable guards in the 2023 cycle: Henry Bainivalu and Jaxson Kirkland. But the team’s best interior offensive line prospect (by far) is still on the way.
Though Troy Fautanu played tackle in 2023, his NFL projection could be particularly fruitful on the interior. That’s where many evaluators see him as a potential impact starter at the professional level.
At 6’4″, 317 pounds, Fautanu has an incredibly compact frame with great mass, and he also brings crisp footwork (aided by his tackle experience), spry recovery athleticism, fast and forceful hands, power drive, and a physical finishing mentality.
He started at left guard against Stanford in 2022, providing a glimpse of his upside from inside alignments. And his ability to be a sledgehammer as a help blocker also tells of that upside.
Who Is the Best iOL in the 2024 NFL Draft?
The 2024 NFL Draft iOL class is incredibly strong and diverse on the surface — but the top prospect on our board at PFN is a tackle who projects especially well on the interior.
This isn’t to say that Duke’s Graham Barton can’t stick at tackle. He certainly could — but his upside inside is incredibly exciting.
1) Graham Barton, G/C, Duke
As mentioned above, Barton is a tackle for the Duke Blue Devils. Here, however, he’s listed as a guard/center hybrid — which may end up being his best projection at the NFL level.
Arm length is a part of the discussion here. Despite standing at 6’5″ and 314 pounds, Barton doesn’t have great proportional length, and that’s often a source of interior talk. Of course, the next question is whether or not he has the technique, active hand usage, and athleticism to counteract that.
Rashawn Slater and Peter Skoronski are two recent prospects who could boast the necessary counteractive measures to stay at tackle, and Barton also has those traits. He’s a violent, intentional hand fighter with twitchy corrective mobility and the flexibility to maintain leverage.
For Barton, the projected move to guard is about something other than necessity. It’s about possibilities.
Barton’s ceiling is high wherever he lines up, and he has pre-existing center experience. But at guard and center, he’s especially enthralling.
Not only is Barton an extremely combative and precise hand fighter, but he’s also a road-grader in the run game, with a unique level of urgent leg drive and explosive athleticism that can dominate against space defenders.
Blocking at the NFL level is about protecting on passing downs and displacing on running downs. Barton’s dual-sided ability to both work in space and create space at contact could make him a game-changer as a guard, both on pulling looks and zone runs.
It’s why he’s a viable first-round candidate for the position and a candidate to be the top iOL prospect.
