CLEVELAND, Ohio — A simple measurement can tell the difference between which offensive line position a player could play in the NFL.
LSU’s Will Campbell came into the draft process as unquestionably the best offensive lineman available. He had 31 career starts at left tackle for the Tigers.
But one key reason he is listed here as an interior offensive lineman is that he has shorter arms. His arms measured at 32-5/8 inches long at the NFL Combine in February. The magic number for [offensive tackle arm length in the eyes of NFL personnel is usually 34 inches](https://go.skimresources.com?id=126006X1587346&xs=1&url=https%3A%2F%2Fwww.espn.com%2Fnfl%2Fstory%2F_%2Fid%2F44067176%2Flsu-ot-campbell-arm-length-scrutinized-nfl-combine).
That’s not to say Campbell can’t be a tackle at the NFL level. He is a very athletic and smart offensive line prospect.
However, when going up against elite pass rushers, teams may typically want a certain prototype for a tackle. Campbell’s limited length could give him an issue against those elite pass rushers.
But there’s no question about his talent and that he can be a Pro Bowler in the NFL. It may come on the inside. However, elite offensive linemen are always in demand regardless of where they line up.
**Where this position ranks in the 2025 NFL Draft?**

**What the Browns need at interior offensive line**
---------------------------------------------------
Joel Bitonio is back for the 2025 season. But he doesn’t have many more years left as a player, and Wyatt Teller is in the final year of his contract.
The Browns did sign Teven Jenkins this offseason and drafted Michigan guard Zak Zinter in 2024. Zinter was a player I thought needed as close to a redshirt year as possible to gain strength off his broken fibula and tibia. So 2025 will be important for him.
That said, you can never have too many offensive linemen, so it won’t be a shock if the Browns draft another interior player for depth and competition.
**Meet the top five interior offensive linemen**
------------------------------------------------
### **1\. Will Campbell, LSU**
**Height, weight**: 6-6, 319 pounds.
**Projected slot**: Top 10
**More about Campbell**: The limited arm length that Campbell has is probably the only knock on his scouting report.
He is a high-end athlete and was a start in college, earning consensus first team All-American honors in 2024. Moving him inside should help him maximize his strengths once he adjusts to the position.
If he is indeed a guard in the pros, this could be the first time since 2018 (Quentin Nelson) that the first interior offensive lineman is drafted before the first offensive tackle.
### **2\. Tyler Booker, Alabama**
**Height, weight**: 6-5, 325 pounds.
**Projected slot**: Late first round.
**More about Booker**: While there is a question about what position Campbell could play in the NFL, there is no doubt that Booker is a guard through and through.
Booker is a powerful offensive lineman who also displays a good football IQ. However, he isn’t a very quick player, especially with his feet.
His best fit in the NFL will likely come from being in a downhill blocking scheme.
### **3\. Donovan Jackson, Ohio State**
**Height, weight**: 6-4, 315 pounds.
**Projected slot**: Late first to early second round.
**More about Jackson**: Jackson came to Ohio State as a five-star offensive line prospect from Texas and he lived up to the status. But what really boosted his draft stock in his final season was how he played filling in for the injured Josh Simmons at left tackle.
Jackson’s play at left tackle was a key to the Buckeyes winning a national championship. Whether he does stay at tackle or goes back to guard, Jackson should be able to be a quality starter in the NFL.
What will help him is his strong upper body and his athleticism, although he has to work on his feet.
### **4\. Grey Zabel, North Dakota State**
**Height, weight**: 6-6, 312 pounds.
**Projected slot**: Late first to second round.
**More about Zabel**: Zabel was one of the stars of Senior Bowl week, and he has kept that momentum going well enough to put himself into first-round discussion.
He played tackle at NDSU but could kick inside to guard like Campbell because of shorter arms.
Zabel has a lot of experience with 38 career starts and the versatility to play multiple positions. He also moves very well, but he will need to get stronger in addition to making the bigger leap in competition compared to his FBS counterparts.
### **5\. Jonah Savaiinaea, Arizona**
**Height, weight**: 6-4, 324 pounds.
**Projected slot**: Late second to third round.
**More about Savaiinaea**: A three-year starter on the offensive line, Savaiinaea has experience played both at tackle and at guard. But his build may have him marked in as a guard in the NFL.
He looks the part of an NFL guard because of his fide frame and the power he plays with.
However, Savaiinaea isn’t a high-end athlete and he needs to continue to work on his feet to succeed at the next level.
