The NFL draft begins Thursday in Chicago, with all 32 teams looking for the next great pro talent to emerge from the SEC.

We’ve taken a position-by-position look at the SEC’s draft prospects in the days leading up to the event. We started with running backs, receivers, defensive tackles, defensive ends, safeties, quarterbacks, tight ends, cornerbacks, offensive tackles and linebackers. We continue today with guards and centers.

Interior offensive linemen never are sexy, and usually don’t get drafted in the first round. But every NFL team needs them, and the SEC is as good of a league as any at producing them.

Versatility and technique often are the most valued ingredients here, and there are several SEC players in the 2015 class who possess both.

Let’s take a look at some of the news, projections and buzz at the position entering this year’s draft.

BIGGEST STAR: A.J. Cann, South Carolina

At 6-foot-3, Cann isn’t the tallest high-round offensive lineman. But he started 51 games at South Carolina, and he makes up for that with good, not great, athleticism (32.5-inch vertical at his pro day, 30 bench press reps).

He’s neither the most athletic player in the world nor the biggest and most powerful. He’s better blocking for the run and needs to work on technique in pass protection, but everything about him is solid.

He’ll likely play left guard in the NFL and could start for a team immediately.

“Nothing about him gets you really excited and nothing about him gets you really down. He’s just a steady player and will probably be a 9 or 10 year starter. I’ll take that,” an NFL offensive line coach told NFL.com.

RISING: Mitch Morse, Missouri

Draft projections and talk make it seem more and more likely that Morse could get drafted on the second day (Round 2 and 3).

He’s not the most physically gifted offensive lineman, and probably will have to move from tackle at Missouri back to guard or even to center in the NFL. (He started 18 games at right tackle, 14 games at left tackle and eight at center for Missouri.) His arms are relatively short and he isn’t fluid with his lower body.

But Morse put up 36 repetitions in the bench press at the NFL Combine, one of the best marks regardless of position, unleashed a solid 31-inch vertical leap and shows a lot of grit in his game film.

“This guy is one tough sucker. You talk about toughness and tenacity. You grade him and he just blocks his guy,” a scout told the Milwaukee Journal-Sentinel.

If a team thinks his smarts and toughness can overcome his lack of natural size, we could see him off the board before Saturday.

FALLING: Jarvis Harrison, Texas A&M

The 6-foot-4, 330-pound Harrison is talented enough to go in the first two or three rounds, physically speaking. But NFL teams must weigh his on-field potential with a number of character concerns.

“I believe he has Pro Bowl caliber talent, but his work ethic is a major concern for me. I know he loves basketball, but not sure if he feels the same about football,” an AFC scouting director told NFL.com.

Said another scout to the Milwaukee Journal-Sentinel: “The trainer will tell the offensive linemen when they come into the locker room to cut the tape off their shoes and put it in a specific pile. Everybody follows that to the letter, but he’ll do something completely opposite. Not very highly regarded at the school. He’s smart enough to know to stay out of the police blotter type of thing. Just a pain in the (expletive).”

Harrison may have the talent to be a standout left guard or even left tackle, being described as a “dancing bear” who eliminates defenders from the play once he latches onto a block. But there’s nothing NFL teams hate worse than “lazy knuckleheads.”

Harrison likely is a third-day pick, but could have huge upside.

THREE BIGGEST QUESTIONS

  1. Will Rimington Trophy winner and Auburn center Reese Dismukes get drafted on the second or third day?
  2. Can South Carolina’s A.J. Cann hold off Missouri’s Mitch Morse as the SEC’s first interior offensive lineman off the board?
  3. Will Georgia center David Andrews get drafted?

THREE TO WATCH FOR 2016

  1. Mike Matthews, Texas A&M
  2. Vadal Alexander, LSU
  3. Ryan Kelly, Alabama

RECENT BUZZ

  • The Bleacher Report’s Matt Miller is reporting that Alabama G Arie Koundjio has failed multiple team physicals due to chronic knee problems. If that’s the case, the projected mid-round pick could fall to the bottom of the draft or out of it altogether. He lacks functional athleticism and is limited to blocks that are right in front of him, which is another strike against him.
  • Despite all the accolades at Auburn, Reese Dismukes is a limited player in the NFL in that he’s unlikely to play anything but center. He’s got small arms and even smaller hands, and he’s a marginal player as a blocker who is much better when he gets out in space. He’s not a Top 5 center in this class, but he’ll get selected on the third day of the draft.
  • At 6-foot-8 and 5/8, 353 pounds, former Florida lineman Trenton Brown spent the pre-draft process trying to convince teams that he’s more than just a big body. He ran well for a guy his size (5.29 in the 40-yard dash). His 35 1/2-inch arms are an asset, and he reportedly had a good pro day in Gainesville, which may be enough to get him drafted Saturday.
  • Max Garcia, another Florida lineman, possesses good functional strength and a strong punch. He’s relatively new to center, but that probably is his best position in the NFL as he’s not good running out in space to block at the second level. His best asset is his natural upper-body power and it could get him drafted late Saturday.
  • Georgia’s David Andrews, Mississippi State’s Ben Beckwith, Mississippi State’s Dillon Day and Auburn’s Chad Slade are among those who could be looking to make a roster as an undrafted free agent.
