Owain Jones: Top 10 iOL Prospects In The NFL Draft - Will Campbell, Tyler Booker & More

By Owain Jones

The 2025 NFL Draft’s interior offensive line class presents an intriguing yet somewhat murky picture. As many college tackles are expected to make the transition to guard or center at the next level due to size and skill limitations, the line between tackle and interior lineman becomes increasingly blurred. Let’s take a look at who projects best as an IOL prospect in the 2025 NFL Draft.

TOP 10 IOL 2025 NFL Draft Rankings

10: Tate Ratledge, Georgia

Tate Ratledge is a robust and tenacious interior lineman with an impressive motor. A key part of Georgia’s dominant offensive line over the last three seasons, the Bulldogs’ guard uses his strength to generate movement in the running game, consistently paving the way for running backs.

9: Emery Jones Jr., LSU

Emery Jones Jr is a powerful offensive lineman who played right tackle for the LSU Tigers. However, he projects best on the interior in the NFL. 

With the ability to move defenders off the ball, Jones has the raw strength to excel as a run blocker. He often efficiently drives defenders backward. However, his ability to keep defenders at bay in pass protection is inconsistent. While he possesses the physical traits needed to succeed, his technique will require refinement, particularly against faster NFL defenders.

8: Anthony Belton, NC State

Anthony Belton is a technically sound offensive lineman with a natural feel for the game. With the ability to play tackle or guard at the next level, the NC State OT consistently displayed his ability to anchor in pass protection and clear running lanes in the ground game.

Belton’s quick hands and sharp footwork allow him to counter and adjust to defensive linemen, while his ability to play with leverage makes him a tough challenge in the trenches. A lack of ideal length should see him slide inside at the next level, where he would excel as an NFL guard.

7: Marcus Mbow, Purdue

A college tackle, Marcus Mbow is another player who projects best inside at the next level. With the versatility to play guard or center, the Purdue prospect has snappy hands and exceptional quickness off the snap and can often get into position early.

Mbow has shown the ability to dominate in space, often getting to the second level and making blocks on linebackers. However, his lack of ideal size and strength means he will play inside in the NFL, with a projection at center looking promising for the Boilermaker.

6: Wyatt Milum, West Virginia

Wyatt Milum brings a unique blend of strength and agility. While he has only ever played at tackle, his lack of arm length and quickness project better inside. With sub 33” arm length, it is difficult to envision a team putting him on an island in the NFL. However, the West Virginia OT is a composed pass protector and has the physicality to absorb contact, meaning he has a high ceiling as a mauler and protector, making him a promising interior player at the next level.

5: Grey Zabel, North Dakota State

Grey Zabel is a massive, physical interior lineman with a relentless style of play who can play all five spots on the offensive line. However, with 32 ¼ inch arm length, the NDSU OL will slot inside at the next level. 

At 6’5” and 316 pounds, Zabel was one of the top players at the 2025 Senior Bowl and possesses impressive movement skills. Given his lanky frame, he plays low, but his strength and ability to drive defenders off the ball make him an imposing figure in the run game. At the same time, his awareness of pass protection allows him to maintain solid pocket integrity.

4: Jonah Savaiinaea, Arizona

Jonah Savaiinaea has the physical traits of a tackle but is likely to transition to guard in the NFL due to his length concerns. While his height and wingspan are impressive for a tackle, his inability to consistently bend and handle speed rushers on the edge makes him a better fit as a guard. 

At Arizona, Savaiinaea showed immense potential as a mauler in the running game, clearing massive holes and overpowering defenders. His ability to thrive in tight spaces and on the interior could make him a powerful addition to an NFL offensive line, where his technique and ability to develop his lateral movement will be key.

3: Donovan Jackson, Ohio State

Donovan Jackson is an athletic and versatile interior lineman who combines strength and agility to dominate at the point of attack. The Buckeyes’ guard took over from Josh Simmons at left tackle midway through the 2024 season and didn’t look out of place. While that may lead some analysts to evaluate Jackson as a tackle, he projects best as a guard who has the versatility to play outside when needed. 

A consistent and dependable pass protector, Jackson is especially effective at sealing the pocket and keeping his quarterback clean. His ability to quickly adjust to defenders’ movements in space and use his powerful hands to counter their moves makes him a top offensive line prospect in the 2025 NFL Draft.

2: Tyler Booker, Alabama

A complete guard prospect, Tyler Booker is clean, refined, technical, and NFL-ready. The Alabama Crimson Tide interior player has been playing at an NFL level for two seasons, and his ability to play low and create leverage with his lower body strength is some of the best in this class.

With a nasty demeanor, Booker is a physical player who can quickly drive defenders backward. He is quick to the second level and has the power to finish blocks with authority.

1: Will Campbell, LSU

Will Campbell is a nimble, technically sound lineman whose athleticism shines in both the running and passing games. For what it is worth, he is the top offensive lineman overall in this class.  However, although his frame is suited for tackle, his sub-34” arms and lack of bend raise concerns about his transition to tackle at the next level. His struggles with length and leverage often lead to an upright stance and missed reps. 

As a result, Campbell projects better as an interior player at the next level. With his strength, technical skill, and mobility, Campbell has the potential to thrive as a guard and could develop into a Pro Bowl-caliber player, making him the top interior offensive line prospect in this class.
