In case you miss any of the positional big boards, they will be listed below:

Quarterback

Running Back

Wide Receiver

Tackle

1. Armand Memebou / 6’4 332 / Missouri

Membou is the best tackle in the class, even as a right tackle prospect. He has all the physical traits to become a franchise blocker in the NFL. PFF graded him as the fifth-best tackle in college last season with a 90.6 overall offense grade. Athleticism isn’t an issue with the former Missouri Tiger star. He’s one of the best overall athletes for the position group. His football IQ and hand usage are impressive as well. Membou is a first-round lock after the offseason process that began in Mobile. It’s a question of whether he is a top ten selection. His athletic and stylistic comparison resembles Jedrick Wills, Jr.

PFF Score: 90.6

Round Projection: Top Ten

Player Comparison: Jedrick Wills, Jr

RAS: 9.90

2. Kelvin Banks / 6’5 315 / Texas

Banks has been a consistently top-rated tackle prospect during the 2024 season, and he’s a surefire first-round selection. He aligned at left tackle for the entirety of his collegiate career. PFF gave him a sky-high grade of 86.2 for the 2024 season; his play reflected that. He missed the game against Texas A&M, missing a prime opportunity against Shemar Stewart, but returned against Georgia in the SEC title game. The Texas tackle has all the physical tools teams look for in a left tackle. His football IQ is another positive trait. Footwork and hands in pass protection are another. His athletic and stylistic comparison profiles towards D.J. Humphries.

PFF Score: 86.2

Round Projection: First Round

Player Comparison: D.J. Humphries

RAS: 8.29

3. Will Campbell / 6’5 319 / LSU

Campbell is being debated as the top offensive tackle on the board, but doesn’t quite have the length to stay there. He settled the argument with a monstrous Combine performance. The former LSU star has been a surefire top ten selection for months. His physical characteristics profile is similar to that of another tweener and first-round selection, Ezra Cleveland. Campbell’s RAS is sky high, resulting in an almost perfect ten on the scale. Could he be a top ten guard at the next level? Most likely. Can he be a top-15 tackle? To be determined but the physical traits and intangibles are there.

PFF Score: 72.2

Round Projection: Top Ten

Player Comparison: Ezra Cleveland

RAS: 9.91

4. Airetonae Ersery / 6’6 331 / Minnesota

Ersery was a standout tackle prospect for the Golden Gophers and offers tackle versatility like many of his classmates. He has the physical tools to stick at left tackle, like the length and weight. The RAS is a good indicator of his athletic ability. PFF graded him impressively with an overall score of 77.5. While he wasn’t outstanding like many of his line peers in Mobile, he more than held his own. The Minnesota man receives significant buzz as a first-round prospect but will settle into Day 2. Power and IQ are the defining traits of his game. He compares stylistically and athletically to former SDSU star Terry Poole.

PFF Score: 77.5

Round Projection: First to Second

Player Comparison: Terry Poole

RAS: 9.42

5. Josh Conerly, Jr / 6’4 311 / Oregon

The Oregon left tackle was generally solid at the Senior Bowl, locking in a likely first-round selection. He had some frustrating moments, including one viral moment against Mike Green. Conerly is a former five-star recruit who lived up to the billing in Eugene and became a top-tier pass blocker. He’s an athletic tackle with good length to remain on the left side. While he has some growing to do, he’s a great pass protector with great football IQ and spatial awareness. The physical traits are there to be one of the best tackles in the league in short order. Can he do it? PFF ranked him very high with an 78.3 overall score. Athletically, he’s similar to Oregon standout Jake Fisher, but stylistically, he’s identical to Tyler Guyton of the Cowboys.

PFF Score: 78.3

Round Projection: First to Second

Player Comparison: Jake Fisher / Tyler Guyton

RAS: 8.85

6. Wyatt Milum / 6’6 313 / West Virginia

Milum had a great 2024 season, as evidenced by the ridicuously high PFF score. He offers immense value as a versatile lineman with reps at tackle and guard in his career. Although he didn’t have the best Senior Bowl performance, the tape doesn’t lie. The former Mountaineer lineman is a technically sound tackle prospect with length issues that will force him inside at the next level. Toughness and technique are the biggest pluses in his game. Teams will likely stick him at tackle before ultimately making the switch inside. His profile compares favorably to Will Fries and should be a Day 2 selection. He missed the top five tackle rankings on this offensive line big board.

PFF Score: 91.0

Round Projection: Second

Player Comparison: Will Fries

RAS: 8.03

7. Jalen Rivers / 6’5 319 / Miami

The former Hurricanes offensive tackle stood out in Mobile as one of the better prospects. He split time between tackle and guard during the week and did not show any dropoff in form. As the RAS indicates, he’s a middling athlete but is an effective one. His position versatility will entice teams to draft him late on Day 2 or early on Day 3. Rivers’ length will allow him to stay at tackle, but the team that drafts him could move him inside to mold an incredibly gifted guard with power as a mainstay in his game. How teams view his medical file will be interesting. His stylistic and athletic comparison is Dalton Risner.

PFF Score: 70.7

Round Projection: Third to Fourth

Player Comparison: Dalton Risner

RAS: 6.61

8. Jonah Savaiinea / 6’4 324 / Arizona

Savaiinea offers great positional versatility as he has experience at both tackle spots and guard. The Arizona lineman stood out at the Senior Bowl, and the remainder of the offseason has been positive for him. He has the athleticism and temperament to play left tackle, but could be an excellent right tackle. Teams will love his versatility and attitude. The RAS is impressive, and he has the length to stick at tackle if need be. Given his physical traits, he can be a good starting guard at worst. His physical and athletic profile resembles the former first-round selection, Ikem Ekonwu. Savaiinea should be a tackle-versatile early Day 3 selection.

PFF Score: 75.9

Round Projection: Fourth to Fifth

Player Comparison: Ikem Ekonwu

RAS: 9.19

9. Ozzy Trapilo / 6’8 316 / Boston College

The BC legacy recruit is a versatile prospect with reps at both tackle spots. His offseason process has been kind to his stock, as he elevated his stock in Mobile and the Combine. He’s all of 6’8 316 and looks the part of an imposing blocker. Trapilo is a better athlete than given credit for as well. The former Boston College star has a strong base and is a technician. Smaller and quicker defenders occasionally take advantage of the leverage against him. The basement of his stock should be the fourth round with the potential to go higher. His play style and athletic comparison are those of former Stanford standout Walker Little.

PFF Score: 76.8

Round Projection: Fourth

Player Comparison: Walker Little

RAS: 8.87

10. Anthony Belton / 6’6 336 / NC State

Belton had a terrific Senior Bowl process that led to him elevating his stock after a great season. He’s every bit of 6’6 336 but moves well for a guy his size. The former NC State lineman is an intriguing prospect for a team looking for a mid-round tackle to supplement their line with a swing tackle. He could fit better on the right side, but is capable on the left. Belton is a true road grader and won’t let anyone forget it. His stock should settle in the early to middle stages of Day 3. The athletic and stylistic comparison for him is that of former Notre Dame star offensive tackle Sam Young.

PFF Score: 73.6

Round Projection: Fifth

Player Comparison: Sam Young

RAS: 8.16

11. Marcus Mbow / 6’4 303 / Purdue

Mbow didn’t get a chance to strut his stuff at the Senior Bowl after missing the last two days of practice due to an illness. He’s a solid prospect on tape with his athleticism and strength. However, the size could be an issue at tackle, but the overall package profiles are better at guard. PFF gave him an overall offense grade of 74.0. He’s a better fit inside due to length and frame. The former Purdue tackle compares favorably to Wes Schweitzer and should be a middle Day 3 selection.

PFF Score: 74.0

Round Projection: Fifth to Sixth

Player Comparison: Wes Schweitzer

12. Carson Vinson / 6’7 314 / Alabama A&M

Vinson proved that the step up in competition wasn’t too big for the big guy at the Senior Bowl. He dominated the proceedings and rarely lost a rep in Mobile. His incredible run of form continued into the Combine, where the former Alabama A&M product starred once more. He has all the physical tools to succeed at either left or right tackle, but should be a long-term starter on the left side. PFF rated him highly, giving him a 75.2 overall offense score. The small school prospect can be selected early on Day 3. His athletic and stylistic profile is similar to Chiefs tackle Wanya Morris.

PFF Score: 75.2

Round Projection: Sixth

Player Comparison: Wanya Morris

RAS: 8.06

13. Cameron Williams / 6’5 317 / Texas

Williams is a right tackle exclusive prospect who started 16 games in his Longhorns career, so he’s still growing into the role. His game features more power than athleticism at this point in his career. Interestingly, Texas went out with a freshman at left tackle rather than Williams when teammate Kelvin Banks was injured. The inconsistency in his career has been maddening to project long-term. If teams can believe in his power-based traits, he should be a Day 3 selection. His athletic and stylistic profile resembles a former Miami Hurricanes lineman turned ACC Network analyst, Orlando Franklin.

PFF Score: 67.4

Round Projection: Sixth to Seventh

Player Comparison: Orlando Franklin

Guard

1. Tyler Booker / 6’4 321 / Alabama

There’s a lot of power in Booker’s game. He’s a physical blocker who doesn’t hesitate to let the defender know it when he makes an impact block. While he isn’t the greatest athlete to ever play the position, he does have some foot speed. The RAS is an off-putting 3.68, which should concern teams about his speed and athleticism at the next level. Booker also offers guard versatility, having experience at both spots, but he’s a left guard by trade. A punishing blocker that demoralizes the defender with his style of play. The former five-star recruit delivered on his hype and should be a first-round selection. Stylistically and athletically, he compares to John Simpson. He’s one of the top overall linemen on the offensive line big board.

PFF Score: 66.5

Round Projection: First

Player Comparison: John Simpson

RAS: 3.68

2. Grey Zabel / 6’5 312 / North Dakota State

Zabel entered Senior Bowl week with the most intrigue and exited with a first-round grade locked in. He was dominant during the week, excelling no matter where he was placed. Teams will love his versatility and consistency, earning an imposing 90.4 grade from PFF. He’s played tackle, center, and guard in college, but the interior is his long-term home in the league. His arm length is perfect for guard and troublesome for tackle, but he projects as a versatile swing piece. Zabel is one of the best offensive line prospects in the class. The former NDSU star lineman compares physically and stylistically to another FCS standout, Ben Bartch.

PFF Score: 90.4

Round Projection: First Round

Player Comparison: Ben Bartch

3. Donovan Jackson / 6’3 315 / Ohio State

Jackson is a former five-star recruit who made good on his collegiate career’s immense promise. He took off as a starter as a sophomore and never let go of his spot. The national champion left tackle moved over to the position due to injury to Josh Simmons. The injury left the Buckeyes scrambling for several games as they got used to the changes. His RAS is among the best for the guard group in the class, with an impressive 8.97 after the Combine. Jackson offers positional versatility for teams that need it. He has the size, power, and athleticism to be a long-term starter at either guard spot, but has played left guard for most of his career. He should be a Day 2 selection and compares stylistically to Phil Haynes.

PFF Score: 71.8

Round Projection: Second to Third

Player Comparison: Phil Haynes

RAS: 8.97

4. Tate Ratledge / 6’6 308 / Georgia

The former Bulldogs lineman is an accomplished prospect who has started multiple games for the powerhouse program. He’s a functional athlete but not outstanding compared to his peers. Teams will ask qbout his medical history as he missed several games due to an ankle issue in 2024. Ratledge is a fundamentally sound lineman, like most Georgia blockers. He earned an overall score of 74.4 from PFF and should be a Day 2 selection. The Bulldogs’ blocker compares stylistically to former Wake Forest star Zach Tom.

PFF Score: 74.4

Round Projection: Second

Player Comparison: Zach Tom

5. Jackson Slater / 6’3 311 | Sacramento State

The FCS lineman had an outstanding Senior Bowl process, excelling at guard and center, showing off versatility to teams. He’s a great athlete with exceptional footwork and proved he could hang with the more prominent names in Mobile. Slater possesses a good size and strength profile for the next level at both spots. He projects better at guard, but could be an ideal swing interior lineman. It’s been a couple of seasons since FCS sent a dominant offensive lineman to the next level, and Slater could be the next star. PFF gave him an overall grade of 76.4. He projects as an early Day 3 selection on the offensive line big board. His stylistic comparison is of the recently retired legend Ali Marpet.

PFF Score: 76.4

Round Projection: Fourth to Fifth

Player Comparison: Ali Marpet

6. Willie Lampkin / 5’10 279 / North Carolina

Lampkin is one of the most intriguing prospects in the class, regardless of position, due to his unique size. His monster Senior Bowl performance got him on the radar further in the process. The former Tar Heels star transferred from Coastal Carolina before the 2023 season. The size is concerning, but he is a talented player, nonetheless. There is some talk that he could transition to fullback, similar to that of Patrick Ricard. Lampkin played guard in college, but his size could limit him to center. He’s a good athlete with good footwork and mobility. Given his size limitations, teams will likely project him as a middle Day 3 selection on the offensive line big board. As a center, he compares to former Oregon pivot man Hroniss Grasu.

PFF Score: 85.6

Round Projection: Sixth

Player Comparison: Hroniss Grasu

7. Luke Kandra / 6’4 319 / Cincinnati

Kandra transferred to Cincinnati before the 2023 season from Louisville. He tested very well at the Bearcats’ Pro Day, and thus the 9.34 RAS. His athleticism on tape isn’t the best, but he steadily improved from year to year. The former Cincinnati man has been one of the lesser-known guard prospects in the class but has risen through the process. He earned a 76.7 overall offense score from PFF in 2024. Kandra has the size and functional athleticism to become an effective starter with some development. He’s projected for the middle of Day 3 on this offensive line big board. Stylistically and athletically, he resembles Braden Smith.

PFF Score: 76.7

Round Projection: Fifth to Sixth

Player Comparison: Braden Smith

RAS: 9.34

8. Miles Frazier / 6’4 317 / LSU

After transferring from FIU, Frazier is a three-year starter at LSU, where he played for two seasons. He’s a versatile athlete with experience at both guard spots and right tackle. Frazier did have a good week in Mobile, which offset some athleticism concerns. He possesses the frame and the road grader mentality to play well in a power-based scheme. The offseason process has benefited him as he posted a 9.30 RAS, further elevating his stock. Teams will slot him in as a guard due to insufficient length for a tackle. He’s projected to be a late-round draft selection on this offensive line big board. His stylistic comparison is Joe Dahl, who played collegiately at Washington State.

PFF Score: 70.4

Round Projection: Sixth to Seventh

Player Comparison: Joe Dahl

RAS: 9.30

Center

1. Jake Majors / 6’3 306 / Texas

Majors is among the best interior linemen prospects in the class, but his length will hamper him against quicker and stronger defenders. The star center anchored the playoff Longhorns for all of 2024, earning a 72.7 overall score from PFF. He started three consecutive seasons for Texas and was nominated for the Joe Moore Award and Campbell Trophy (Academic Heisman). However, he’s a limited athlete who gets by with tremendous positional IQ and experience. The senior center will be a coveted prospect after a good Combine performance. He should be a Day 2 selection, but could slip to early Day 3 as it is on this offensive line big board. His athletic and stylistic profile resembles the outstanding Rodney Hudson.

PFF Score: 72.7

Round Projection: Third to Fourth

Player Comparison: Rodney Hudson

2. Jared Wilson / 6’3 310 / Georgia

Wilson needed a good Combine performance after opting out of the Senior Bowl, and he delivered. He’s one of the best center prospects in the class and could have the most upside. The RAS is tremendous, as the Bulldog ran a blistering 4.84 in the 40 in Indianapolis. He earned a 79.6 overall score from PFF, one of the highest among interior linemen. The former Bulldogs anchor has only one season of starting experience, so the prospect still has some growing left. Wilson is a great athlete who can accelerate quickly to the second level and stay in base longer. Georgia’s starting center should go on Day 3, but there is an outside chance that Wilson moves into Day 2. Athletically, he profiles like Quinn Meinerz, but his play style indicates Matt Hennessy.

PFF Score: 79.6

Round Projection: Fourth

Player Comparison: Quinn Meinerz / Matt Hennessy

RAS: 9.85

3. Jonah Monheim / 6’4 302 / USC

Monheim is a versatile lineman with center, guard, and tackle reps throughout his career. He carried over his good Senior Bowl performance into the Combine. He displays significant functional athleticism, refined footwork, and an excellent football IQ. The former Trojan is a technician who combats defenders with a great base and hand usage. Teams will love his versatility, but he’s a center at the next level. He is likely selected during the middle of Day 3. His stylistic comparison resembles former Texas lineman Kasey Studdard.

PFF Score: 70.9

Round Projection: Fifth to Sixth

Player Comparison: Kasey Studdard

4. Seth McLaughlin / 6’4 304 / Ohio State

The Rimington Trophy winner is a talented center with great football IQ that translates to the next level. He’s a good athlete who diagnoses the defensive scheme quickly and acts upon it. However, he’ll need a redshirt season to recover from an Achilles tear he suffered in late 2024. He has enough athleticism to pull and accelerate to the second level when healthy. Length is a concern for him as well. Due to injury, teams will likely downgrade him into the late stages of Day 3. His stylistic comparison is that of former University of Washington center Luke Wattenberg. The national champion prospect transferred to Ohio State after a dramatic exit from Alabama before 2024.

PFF Score: 70.7

Round Projection: Sixth

Player Comparison: Luke Wattenberg
