Leonard Fournette. Nick Chubb. Derrick Henry. Jonathan Williams. Alex Collins. Russell Hansbrough. Jalen Hurd. The list continues.

The SEC’s cadre of talented running backs will not reach their potential in 2015 without some human bulldozers clearing space out in front. Some of the conference’s best running offenses must replace some premier offensive line talent in 2015.

Which schools will have an easy time slotting another talented body into position, and which ones still will be searching for answers once the season starts?

AUBURN C REESE DISMUKES

Hey, look on the bright side: whomever replaces Dismukes at center likely will have bigger hands.

OK, jokes aside, Dismukes won the Rimington Trophy as the nation’s best center in 2014. The Tigers now have lost Dismukes, left tackle Greg Robinson and H-back Jay Prosch in the last two seasons. That’s a big talent drain for a team that runs so much read option.

Fortunately, Auburn is well-positioned at center in ’15.

Austin Golson, 6-foot-5 and 310 pounds, played 12 games for Ole Miss as a true freshman in ’13, mostly at guard. The Rebels listed him at right tackle entering spring practice last year before he transferred. Forced to sit out last season due to NCAA rules, Golson practiced at center, so he’s had plenty of time to adjust to the new position.

Golson is splitting reps this spring with Xavier Dampeer, who spent last season as Dismukes’ backup. Dampeer played in five games, handling some snaps with the starting offense against opponents like FCS member Samford. The junior college transfer also got to Auburn in ’14, and at 6-foot-2 and 296 pounds, has one more year to make an impact.

The Tigers probably have two capable players at the position, so expect whomever wins the job to be prepared.

LSU LT LA’EL COLLINS

The Tigers got great news when both Vadal Alexander and Jerald Hawkins decided to return for their senior seasons.

Like many offensive linemen in the SEC this year, both players are slated to start at new positions this fall. Alexander, now 6-foot-6 and 320, has slimmed a bit since he arrived in Baton Rouge in 2012. He’ll shift from left guard to right tackle.

Hawkins, at 6-foot-6 and 309 pounds, played right tackle in ’14, but is a more natural fit at left tackle. While Collins is one of the best left tackles in the SEC in years at driving defensive linemen off the ball in the running game, Hawkins is more athlete than brute force. He’ll face more speed rushers on the left side, but has worked to build strength for run-blocking.

“I feel like I’ve gotten stronger in my core and my legs,” Hawkins said, according to NOLA.com. “That’s a big difference and it’s very important as an offensive lineman. I need to bring up my run blocking and a strong core helps you come off the ball faster.”

LSU probably won’t be as good at left tackle in ’15, but with some young, developing players on the interior of the line and a reliable pair of bookends, the overall unit could be as good or better.

MISSISSIPPI STATE RG BEN BECKWITH AND C DILLON DAY

Mississippi State’s losses on the offensive line are a microcosm of what’s happened with the entire team. The Bulldogs are one of three SEC teams (Florida, Alabama) returning fewer than three starters on the offensive line.

If Beckwith, a first-team All-SEC guard, was the most skilled offensive lineman on last year’s team, Day set the tone with a nasty streak that helped the Bulldogs match up with the biggest, baddest defensive lines in the conference. Replacing them is one of the biggest priorities of this offseason.

If the Bulldogs regress in the running game this fall, it will be more due to inexperience along the offensive line than having to replace Josh Robinson in the backfield, though the running back was fun to watch.

But Beckwith and Day weren’t the first physical, mean offensive linemen State has produced, and there are likely to be more. Jamaal Clayborn (center) and Devon Desper (right guard) have started spring practice as the replacements, according to The Clarion-Ledger. Center is the big question mark, and we’ll know more after Mississippi State’s spring game.

TEXAS A&M OT CEDRIC OGBUEHI

The Aggies churn out potential first-round picks at left tackle every year. Right tackle has become an incubator for the position, and this year could follow that pattern.

Ifedi missed two games due to a knee injury in November and at times struggled against the bull rush at right tackle last season. He’s got an NFL future, but it remains to be seen if it’s at left tackle, right tackle or as a reserve swing tackle. I digress — A&M could do worse than Ifedi at left tackle if that’s what the team decides.

Gennesy, a touted JUCO transfer who redshirted last season, will push him hard for the starting spot this spring. If the 6-foot-5, 310-pound junior wins the job, it won’t be difficult for Ifedi to transition back to the right side.

Overall, the A&M offense needs to play better as a unit, especially against hefty, powerful defensive lines like Arkansas and Alabama. But the team’s talent at the tackle positions should approximate what Aggies fans are used to seeing.

FLORIDA LT D.J. HUMPHRIES AND C MAX GARCIA

The Gators are in crisis mode at offensive line this spring.

Five-star offensive tackle Martez Ivey will try to do his best Cam Robinson impression as a true freshman, holding down the quarterback’s blind side throughout the SEC schedule.

The greater concern — although there’s plenty to go around — is at center. Florida hoped fifth-year senior Trip Thurman would start at the position, but he’ll miss all of spring practice with a chronic shoulder injury.

Right now the Gators are just trying to keep the seven scholarship offensive linemen healthy so the team can stage some semblance of a spring game after the remaining practices. If the team can get healthy by fall practice, along with ’15 class reinforcements, the team will be in position to sprint toward the season opener, figuring out the offensive line just in time.

GEORGIA C DAVID ANDREWS

Andrews earned All-SEC status last season, but more than that, got a heap of credit for turning the Bulldogs into one of the most effective run-blocking groups in the country. The team had — and has — talent, but played even better as a unit than the individual skill sets would indicate.

The Bulldogs return every other starter and a loaded backfield, but must find someone who can replace Andrews. The Ledger-Enquirer recently listed four different players at the position on Georgia’s projected depth chart, highlighted by the word “unknown.” Athlon Sports said Isaiah Wynn and Hunter Long will compete for the job.

Whomever starts at center must do more than handle the position physically, though some of the other experienced players — Kolton Houston, perhaps? — can shoulder some of the leadership responsibilities. Overall, UGA again is in great shape along the offensive line.

SOUTH CAROLINA LT COREY ROBINSON AND LG AJ CANN

The Gamecocks must rebuild the left side of the offensive line.

Right now, the position is a Rubik’s Cube that position coach Shawn Elliott is trying to twist and massage into place.

Rising junior Cody Waldrop, healthy after fighting through multiple injuries last season, is working at left guard and could stick at the position.

Left tackle is more complicated. The 6-foot-9 Mason Zandi started spring practice at the position. Rising senior Brandon Shell, currently penciled into the depth chart at right tackle, is missing spring practice due to a shoulder injury. He could flip to left tackle once he’s healthy.

D.J. Park and Mike Matulis also are competing at tackle, according to The Post and Courier.

The good news is that South Carolina’s offensive line features several versatile players, so Elliott should be able to mix and match as necessary, and the Gamecocks are well-positioned should injuries occur in the fall.
