With an 85-scholarship limit, it only takes one or two injuries or transfers at a single position to create some major deficits.

There are several such positions scattered throughout the SEC this year, and we found eight that are particularly thin. Florida even made the list twice.

Keep in mind “thin” doesn’t equal talentless. Some of these position groups, if they avoid further attrition, could be among the best in the SEC. But position coaches and coordinators at these schools should get pretty nervous any time players in these roster spots head to the training room with a limp.

TENNESSEE RUNNING BACKS

The Vols may have one of the best one-two backfields in the SEC East this year (three, if you count QB Joshua Dobbs). But Tennessee better hope super sophomore Jalen Hurd and JUCO standout Alvin Kamara stay healthy, because there’s very little behind those guys.

Tennessee’s roster includes a pair of walk-ons listed at 5-foot-7, 161 pounds and 5-foot-8, 177 pounds, respectively. Then there’s Joe Young, whom the Vols flipped late from Charlotte when it became clear the team needed backfield depth.

Young is a true freshman and a consensus two-star prospect who apparently will “blueshirt,”or walk on with a good chance to earn a scholarship in the future.

FLORIDA OFFENSIVE LINE

At this point Florida’s offensive line may be a touch underrated, but the Gators did go through the end of spring practice with just six scholarship players at the position.

If Trip Thurman can stay healthy, at least Florida will start a veteran on the interior, likely at center. Sophomore David Sharpe still must develop, but the 6-foot-6, 350-pound mammoth has potential to be very good at left tackle. Five-star true freshman Martez Ivey will be counted on immediately at right tackle, but he’s a rare talent.

The unit is loaded with freshmen who will arrive this fall, but very, very short on experience. Any significant injury could devastate this group.

ALABAMA RUNNING BACKS

The Tide backfield exited spring arguably as the single-most talented position group and team in the SEC with three five-star players and two four-star players.

Bo Scarbrough tore his ACL, though, and should miss at least the majority of the season. And DeSherrius Flowers, taking third-team reps for much of the spring, was ruled academically ineligible. That’s not to mention Tyren Jones, dismissed from the team due to continuous off-field issues, or Altee Tenpenny, who transferred this offseason.

Derrick Henry will have to shoulder a huge load, and the Tide is in deep water if he gets hurt. Kenyan Drake is more of a dynamic pass-catching threat, and is returning from a broken leg. Damien Harris is a true freshman who has yet to practice with the team. The Tide recently added a walk-on running back who very well could play in ’15.

LSU LINEBACKERS

The Tigers could enter the fall with as little as six scholarship linebackers, as Kwon Alexander entered the NFL draft after three years and former five-star signee Clifton Garrett decided to transfer.

Former safety Devin Voorhies likely will remain at his new position, and defensive end M.J. Patterson could switch as well.

At least middle linebacker Kendell Beckwith looks like the team’s next superstar at the position. Outside ‘backer Deion Jones is solid, as is Lamar Louis. But injuries are a major concern, as the two-deep isn’t promising.

KENTUCKY QUARTERBACKS

Reese Phillips tore his Achilles this spring. Though he never was officially ruled out for 2015, a return this season seems very unlikely. Considering former starter Maxwell Smith graduated in January and transferred to San Diego State, the Wildcats are very thin at quarterback.

Luckily, the team has two promising players in junior Patrick Towles, last year’s starter, and Drew Barker, a pesky redshirt freshman. If one of those players gets hurt, UK essentially will play ’15 without a true backup quarterback.

ARKANSAS LINEBACKERS

The Razorbacks were thin at linebacker after the departure of NFL draft pick Martrell Spaight. Then the team dismissed Randy Ramsey, who was expected to be an important contributor in 2015.

Coach Bret Bielema has touted Brooks Ellis, now playing weakside linebacker, as a potential All-SEC candidate, and Khalia Hackett is a decent young talent at middle linebacker. Outside of that, the team must rely on Josh Williams, who wasn’t even rated by recruiting services out of high school, and Josh Harris, a 5-foot-10 walk-on.

OLE MISS TIGHT ENDS

The Rebels exited spring rivaling Arkansas for the best tight ends in the SEC. That was before coach Hugh Freeze dismissed promising backup Sammie Epps, a redshirt freshman.

Ole Miss still features potential All-American Evan Engram, but the team already was thin at the position before losing Epps.

Hours after that announcement, the Rebels added Dillon Barrett, a 6-foot-5, 235-pound graduate transfer from Lamar. The team also features Willie Hibbler, a three-star member of the 2015 class who did not arrive in Oxford until after spring practice.

The roster includes several walk-on players at the position, but beyond Engram and two newcomers, there’s not much there.

FLORIDA LINEBACKERS

Despite low numbers, the Gators have a chance to be very good here if Antonio Morrison and Jarrad Davis recover from significant knee injuries. It’s not a given that they’ll both be 100 percent to start the season.

Juniors Alex Anzalone and Daniel McMillan played well this spring, and there are some strong pieces along the defensive line and in the secondary. Jeremi Powell, Matt Rolin and Rayshad Jackson also are on the roster at linebacker, but aren’t expected to contribute much in ’15.

Again, if Morrison or Davis is hurt, this position starts to look dicey.
