Taking a closer look at the offensive lineman who performed well at the 2025 NFL Combine.
Day 4 of on-field drills featured the offensive line, bringing the 2025 NFL Combine to a close. The Detroit Lions ‘ offensive line is a massive part of their identity, and they smartly invest in the group each year to keep them near the top of the NFL.
While their starting offensive tackles feature All-Pro Penei Sewell and a Pro Bowler Taylor Decker, they could still be in the market for depth. On the interior, Kevin Zeitler is a pending unrestricted free agent and Graham Glasgow is nearing 33 years old, so the Lions could be in the market for an immediate starter or future starter on the interior offensive line to pair with Christian Mahogany at guard.
Here are the position groups we’ve covered so far at this year’s NFL Combine :
- Interior defensive lineman
- Edge rushers
- Off-the-ball linebackers
- Cornerbacks
- Safeties
- Tight ends
- Running backs
- Wide receivers
We previously explored some of the prospects we kept close eyes on during Day 4, and if you missed it, be sure to check out these articles for more information: Previewing the offensive tackles and interior offensive linemen ahead of the 2025 Combine .
And with that, let’s look at the offensive linemen who stood out on Day 4 of on-field drills.
Plug-and-play tackles with guard range
Will Campbell (LSU ) and Armand Membou (Missouri) entered the Combine as potential top-half of the first round prospects and both were tremendous in testing and on-field drills. While both have tackle and guard range, they seem destined to be selected ahead of the Lions’ projected range. However, there were two other prospects with tackle and guard range that could be potentially within striking range of Detroit.
Kelvin Banks Jr, T/G, Texas (6-foot-5, 315) has the frame of an offensive tackle but showed terrific movement—especially on pulls and screens—that point to guard potential. He’s a load when he gets moving, showing good balance and comfortable movements in tight spaces. His pass pro was smooth and fluid, and he was quick to get set.
Josh Conerly Jr., T/G, Oregon (6-foot-4 1⁄2, 311) is a very good athlete—his 1.71 second 10-yard split was the fastest of the offensive line groups—and it showed in on-field drills. He found great balance when setting up low, was quick when moving laterally, and smooth when pulling. An all-around easy mover, Conerly’s change of direction was terrific, as was his ability to cover space quickly. He looks like a natural left guard in the Lions’ blocking scheme, but there will be teams looking for a tackle who will also consider him in the first round.
Plug-and-play guards
Tyler Booker, LG, Alabama (6-foot-4 1⁄2, 321) may have caused some pause with his 1.96 second 10-yard split, but his on-field workout illustrated why he could be the first interior offensive lineman off the board. His lateral movement was outstanding, as was his ability to pull and get out on screens. His balance was off-the-charts both when on the move and in pass protection. In the run game he was fluid moving in both directions, but in pass sets, he was significantly more natural moving left as opposed to right.
Grey Zabel, IOL, North Dakota State (6-foot-6, 312) didn’t run, as he was dealing with a minor injury, but it didn’t hamper him in the slightest during on-field drills. A very fast glider, Zabel slid laterally and mirrored as well as any linemen at the Combine. His easy movements also showed up in pulling drills, where he was able to remain balanced and under control despite his speed. As much technical finesse as there is to his game, his power showed up when the chest plates came out, as his aggression seemed to ramp up another level. Many view him as the best center prospect in the draft, but he should be able to play all three interior spots—and maybe more.
Donovan Jackson, LG, Ohio State (6-foot-3 1⁄2, 315) didn’t run but opened on-field drills with low lateral movement and balance. He showed power in his movements and balance when pulling. However, he appeared to injure himself in a pass pro drill and received a thigh wrap from trainers and returned to action. Jackson toughed it out the rest of the way but you could see he was hurting. You have to like the toughness and hope he’ll be able to continue his offseason training.
Tate Ratledge, RG, Georgia (6-foot-6 1⁄2, 318) ran a 1.72 second 10-yard split and proved to be more athletic than his game film showed. Known for being a mauler—which did show up in drills—Ratledge has great feet in lateral movement drills, kept square and balanced, and transitioned with great acceleration in pulling drills. He was an easy mover in pass pro, showing more range than expected.
Should challenge for starting role as rookie
Jonah Savaiinaea, G, Arizona (6-foot-4, 324) ran a 1.72 second 10-yard split, showed tremendous balance in all drills, getting and staying low and under control at all times. His stout frame was balanced when on the move, while he looked long in pass pro situations. His ability to stay low while maintaining speed was the best I saw at the Combine.
Marcus Mbow, G, Purdue (6-foot-4, 303) didn’t run but showed off his athleticism during drills. His movement was fluid all day, firmly setting up in pass pro, and quickly pulling to his marks. His ability to adjust quickly showed up on the screen drill when a coach on the field was late in giving him a direction and Mbow managed to not plow him over.
Wyatt Milum, G/T, West Virginia (6-foot-6 1⁄2, 313) is a bit of a difficult evaluation and probably why I left him off my watchlist. His size screams tackle—and he could probably play there in some schemes—but he moves more like a guard. He’s fast to transition, gets moving quickly, and stays square and balanced on pulls. In pass pro he looked totally relaxed, which is no surprise considering his experience is at tackle. I think he has long-term starting range at right tackle, but could also fit in at guard.
Joshua Gray, LG, Oregon State (6-foot-5, 299) is a fun evaluation. A four-year starter at left tackle, he pushed inside to guard as a super senior to maximize his NFL appeal—and it worked, because he certainly looks like an NFL guard. Gray has solid lateral movement, is better as a puller, but moves easily in most situations. He covers a lot of ground when on the move, steps with power, and easily matched his mirror. I think he has the range to stay at guard and experiment at center as well.
Draft and develop
Jalen Rivers, G/T, Miami (6-foot-6, 319) looks more like a tackle than guard, but he was a smooth puller in drills and transitioned with balance throughout the afternoon. He’s a tick slow when shifting but showed a ton of patience in pass pro. There are developmental skills if he slides in the draft.
Miles Frazier, RG, LSU (6-foot-5 1⁄2, 317) showed very good speed in pulling drills, was calm when moving laterally, and was able to react/recover on the fly. He had good technique in pass pro and was able to drop deep into sets without any struggles.
Miles Hinton, T/G, Michigan (6-foot-6 3⁄4, 323) played nearly 2,000 snaps at tackle in his college career but just one at right guard. Still, he may benefit from a switch inside in the NFL. Despite his large frame, he reminds me a bit of Halapoulivaati Vaitai with his smooth lateral movements and pulling power. He covers ground quickly, showing nice length and balance when on the run. It’s also worth noting that Hinton was recruited to Stanford (before transferring to Michigan) by Lions passing game coordinator David Shaw.
Drew Kendall, C, Boston College (6-foot-4, 308) is a natural center who could have the range to split out to either guard spot, as he showed great movement in both directions in drills. His quick lateral movement translated to smooth pulling after the snap, and terrific acceleration on screens.
John Williams, T, Cincinnati (6-foot-4, 322) was not on my radar coming into the Combine but he caught my eye with his aggressive movements and quick get off. Laterally, Williams is very fast, showed great movement on screens, transitioned well on pulls, and stayed square and balanced in pass pro. Despite his experience all coming at tackle, he looks like he has the range to play guard in the NFL as well.
