2015 NFL Draft rankings: Top 10 interior linemen

Ranking the top 10 interior linemen in this year's NFL Draft.

Kim Klement-USA TODAY Sports
1. Brandon Scherff (Iowa) | 6-foot-5, 319 pounds

I consider Scherff to be a top-10 talent. He spent most of his college career at left tackle for the Hawkeyes, but it’s likely that he’ll either move to the right side or play guard in the NFL. His combination of size, strength and athleticism makes him the most pro-ready offensive lineman in the NFL Draft.

Projection: Top-10 pick (CBS Sports)
Grade: 6.4 (

2. Cameron Erving (Florida State) | 6-foot-5, 313 pounds

As an offensive tackle prospect, Erving struggled badly with keeping his balance in pass protection and securing the edge. After making the switch to play center, nearly all of his problems diminished. Not many can make the move that he did, but he looks like a natural. He’s a great athlete with great feet and nice length, and he has all the tools you want in an interior lineman.

Projection: Late 1st round (CBS Sports)
Grade: 5.7 (

3. A.J. Cann (South Carolina) | 6-foot-3, 313 pounds

There’s a pretty big gap in talent between my top two guys and the rest of this list if you ask me. Still, Cann is a powerful guard prospect who will thrive in a power running scheme. He has decent foot quickness, but he appears to be more comfortable when operating in a phone booth rather than in open space.

Projection: 2nd round (CBS Sports)
Grade: 5.8 (

4. Jeremiah Poutasi (Utah) | 6-foot-5, 335 pounds

Poutasi started his last two years at left tackle for Utah, but appears to be a candidate to move inside. He was consistently beaten by speed rushers as a tackle, and moving inside should mitigate some of his struggles. He’s a big body who can wipe defenders out in the run game, and I believe a lot of draftniks are sleeping on him as a guard prospect.

Projection: 5th-6th round (CBS Sports)
Grade: 5.4 (

5. Laken Tomlinson (Duke) | 6-foot-3, 323 pounds

Tomlinson is a prime example of why you should always accept an invitation to the Senior Bowl and/or Shrine Game. He went from a projected fourth- or fifth-round pick to a near lock for the second round after an impressive week of practices at the Senior Bowl. Tomlinson models his game after Larry Warford and will be a solid pick on the second day of the draft.

Projection: 2nd round (CBS Sports)
Grade: 5.6 (

Apparently, Laken Tomlinson is actually Wonder Woman.

6. Tre' Jackson (Florida State) | 6-foot-4, 330 pounds

Florida State really knows how to produce some solid O-line talent. The Seminoles could have three guys on this list if one didn't test historically bad – I’m looking at you, Josue Matias – during the combine. Jackson packs a powerful punch and is a monster in the run game. He tends to struggle a bit more in pass protection and will often set his anchor late, but overall there’s plenty to like about him.

Projection: 2nd-3rd round (CBS Sports)
Grade: 5.8 (

7. Quinton Spain (West Virginia) | 6-foot-4, 332 pounds

Spain is being criminally undervalued if you ask me. He’s a converted tackle with great short-area quickness and generates plenty of push at the point of attack. He reportedly ran a 4.97 40-yard dash at his pro day, which is incredible for an O-lineman. My biggest concern with Spain is the consistency with his hand placement, but he has a ton of traits that coaches will love to work with.

Projection: UDFA (CBS Sports)
Grade: 5.2 (

8. Ali Marpet (Hobart) | 6-foot-4, 307 pounds

I hate to put Marpet on this list only because it’s virtually impossible to find any tape on him unless you have a direct connection to his agent or any NFL scouts. However, his combine numbers simply cannot be ignored, and there are too many respectable draft pundits out there praising him as a Day 2 pick.

Projection: 2nd-3rd round (CBS Sports)
Grade: 5.5 (

9. Hroniss Grasu (Oregon) | 6-foot-3, 297 pounds

Grasu is my No. 2 center in a generally weak class. He has nice athleticism and does well at getting out to the second level and carrying out blocks. He’ll need to add some strength to compete at the next level, but he has the frame to do it.

Projection: 2nd round (CBS Sports)
Grade: 5.6 (

10. Mark Glowinski (West Virginia) | 6-foot-4, 307 pounds

Glowinski is another WVU guard who has flown under the radar. Like Spain, he’s a converted tackle with great upper-body strength and superb athleticism. Glowinski looks strong as hell on tape, and if he’s able to find some consistency with gaining leverage at the point of attack, then he’s going to be a really nice find for someone in the later rounds.

Projection: 7th-UDFA (CBS Sports)
Grade: 5.4 (
