There are always a couple of players on each football team that you just can't replace. Most of the time they are quarterbacks, but every so often someone else emerges as that indispensable player teams just can't live without.
Today, we're looking at those players. It's easy to talk quarterbacks being the most important people on a team, so we decided to look at the most indispensable players on each SEC school who aren't lining up under center.
Here's our list for the 2013 season:
C.J. Mosley, LB, Sr.
Nothing about C.J. Mosley's game fits the typical Alabama mold. He's rarely the biggest or the strongest player on the field. Next to Courtney Upshaw and Dont'a Hightower, he looked like a safety. But Mosley's sideline-to-sideline speed is outstanding, and in a league that continues to feature mobile quarterbacks that trait is invaluable. Last season Mosley became the first Alabama defender to break the 100-tackle mark since Rolando McClain, and he did it while splitting time. Now that the job is all his, it's up to Mosley to do even more in terms of production and leadership. -- Alex Scarborough, TideNation
Travis Swanson, C, Sr.
The 6-foot-5, 314-pound Swanson has started all 38 games of his career and was a second-team All-SEC selection last year. He has blocked for three 3,000-yard passers and will be an integral part of the Razorbacks this year as well, as they move to a more run-oriented attack under new coach Bret Bielema. The new head coach has been quoted as saying Swanson is the "best center in college football." That's high praise from a coach who has seen plenty of talented offensive linemen over the years. -- Sam Khan, GigEmNation
Reese Dismukes, C, Jr.
All eyes will be on first-year starting quarterback Nick Marshall, and although Auburn has plenty of skill players for him to utilize, the most important player will be the one who is snapping him the football. In his first two seasons on The Plains, Dismukes has started all but two games at center. He’s become a mainstay on the offensive line and was a constant even through all of the turmoil a year ago. He’ll be counted on again this year to serve as the rock for Marshall and the entire offense. -- Greg Ostendorf, TideNation
Matt Jones, RB, So.
This is bad news for the Gators because they may very well be without Jones for the season opener against Toledo -- and possibly beyond -- because he has not yet been cleared to return to the field (viral infection). The 6-foot-2, 226-pound Jones is a bruising runner who was a perfect fit for the Gators’ between-the-tackles running game. He is UF’s best offensive player and his top backup is Mack Brown, who has just 40 carries in three seasons. -- Mike DiRocco, GatorNation
Damian Swann, CB, Jr.
The first name that comes to mind is Todd Gurley, who will surely rank among the nation’s top tailbacks. But Georgia’s ship probably wouldn’t sink if it relied on Keith Marshall to carry the running game. Perhaps Georgia’s most indispensable player is on defense. Cornerback Damian Swann -- who led the team with four interceptions last year -- is the only returning starter in the secondary and is one of the young defense’s clear leaders. -- David Ching, DawgNation
Alivn "Bud" Dupree, DE, Jr.
It will be interesting to see how Dupree transitions from linebacker to end this fall, but regardless of position, he’s the best player on this UK defense. And there’s no doubt it will be a defense that new head coach Mark Stoops will count on to keep them in games. As a sophomore, Dupree emerged as one of the SEC’s top pass-rushers, finishing with 91 tackles and seven sacks. This fall, he’ll also serve as a mentor to newcomers Za'Darius Smith, a junior college transfer, and Jason Hatcher. -- Greg Ostendorf, TideNation
Anthony Johnson, DT, Jr.
With a rebuilt defensive line, Johnson has become arguably the Tigers' most important player outside of quarterback Zach Mettenberger. He's strong, big, athletic, fast and ready to live up to his full potential as "The Freak." He'll anchor LSU's defensive line. Without him, the Tigers have a gaping hole in their relatively younger defense. Johnson is the team's best run stopper, but also has the ability to rush the passer and make plays outside of the box. -- Edward Aschoff
Gabe Jackson, OG, Sr.
The Bulldogs have a lot to replace in the receiving game, but if the offensive line doesn't come together, the offense will be in trouble. Jackson is the heart and soul of Mississippi State's offensive line and without him, the Bulldogs could have big problems up front this fall. He's an NFL prospect and is great pushing the run and protecting the pass. Losing him would greatly set this unit back. -- Edward Aschoff
Evan Boehm, C, So.
The 6-foot-3, 315-pound Boehm is the Tigers’ best offensive lineman despite being only a sophomore. He moved from guard in the spring and struggled a bit with the transition, but is settling into the position. Boehm was the only lineman who didn’t miss a game last season and those injuries played havoc with the offense. Missouri has the offensive weapons to score points, but the line has to be better and stay healthy. That begins with Boehm. -- Mike DiRocco, GatorNation
Donte Moncrief, WR, Jr.
The Rebels have some depth at receiver, even with Vince Sanders going down this preseason with a broken collarbone. But they don’t have anybody quite like Moncrief, who caught 10 touchdown passes last season and opens up the field for everybody else. He takes plays that should go for minimal gains and turns them into touchdowns, and he wins one-on-one battles with cornerbacks even when the ball isn’t thrown perfectly. Defenses have to play the Rebels differently when Moncrief’s on the field. -- Chris Low
Jadeveon Clowney, DE, Jr.
Clowney is easily the best defensive player in the country and he might be the nation's best overall player, regardless of position. He has incredible measurables, elite speed and athleticism, and is stronger than an ox. Without him, South Carolina's new-look defense would take a major hit in 2013. He's the motor that makes that defense run and is the main reason why the Gamecocks have the SEC's best defensive line. His mere presence on the field makes teams change their game plans. -- Edward Aschoff
Antonio Richardson, OT, Jr.
Call him "Tiny" at your own peril. Tennessee's Antonio Richardson is anything but small. The 6-foot-6, 327-pound offensive tackle is a mountain of a man, and the Vols will need every bit of protection they can get when they find their quarterback of the future. If Richardson can help relieve the pressure on the passing game and help open up holes in the running game it would go a long way in helping an offense in transition under new coach Butch Jones. -- Alex Scarborough, TideNation
Jake Matthews, OT, Sr.
When looking at non-quarterbacks, the guy who protects the quarterback's blind side is of utmost importance. Last season, Luke Joeckel had a stellar season in that role while Matthews was anchoring the right side of the line. This year, Matthews, son of NFL Hall of Famer Bruce Matthews, slides to left tackle. There's no reason to believe Matthews will miss a beat and he has the look of a high first-round pick in the 2014 NFL draft. Kevin Sumlin calls Matthews a classic "low maintenance, great player." -- Sam Khan, GigEmNation
Jordan Matthews, WR, Sr.
Coming off the best season by a Vanderbilt receiver (94 catches, 1,323 yards, 8 TDs), Jordan Matthews is the clear pick. Chris Boyd will also produce big numbers, but it’s unusual for a Commodore to claim the SEC’s career lead in a top statistical category. Matthews can do that in receptions (he has 150, needs 86 to tie Vandy’s Earl Bennett’s record) and receiving yards (has 2,290, needs 803 to tie Georgia’s Terrence Edwards) if he duplicates last season’s numbers. -- David Ching, DawgNation
