NCF Nation: Shane McCardell

Today we look at the big uglies that cause all the mayhem in the trenches. The SEC consistently spits out nasty defensive linemen and this year has more of an athletic feel.

Here's how the teams stacked up:

1. South Carolina: The Gamecocks return a defensive line that would make any offensive line shutter. Plus, incoming freshman Jadeveon Clowney comes in as the top high school player in the country and could be one of the best ends in the league this fall. Devin Taylor leads the group at end and was second on the team with 7.5 sacks as a sophomore. Helping on the outside is Melvin Ingram, who plays inside on passing downs, and led South Carolina with nine sacks a year ago. Senior Travian Robertson, who came off injury to get four sacks last year, is solid in the middle as well.

2. Arkansas: The Razorbacks might have the best pass-rushing group Arkansas has seen in a while. Things revolve around defensive end Jake Bequette, who was one of the more unheralded players in the league last year, despite having seven sacks. On the other side of the line is Tenarius Wright, who will make up the second part of a formidable outside duo in Fayetteville with his speed and athleticism. In the middle, there are plenty of options. Byran Jones and DeQuinta Jones missed spring due to injury, but will be back this fall and there’s a wealth of depth behind them. Junior college transfer Robert Thomas might be the best and most athletic option in the middle is primed to break out.

3. LSU: There are some questions about the experience the Tigers bring back, but no one will question the talent and athleticism in Baton Rouge. Sam Montgomery is back at defensive end, after suffering a serious knee injury. He hasn’t played much, but the coaches believe he’s got what it takes to be a top end in this league. Kendrick Adams started 11 games last year at end, while Lavar Edwards filled in for Montgomery. Ego Ferguson redshirted last year, but should get a ton of playing time in the middle this fall. He is already one of the most athletic tackles in the SEC. Don’t forget about five-star early enrollee Anthony Johnson, who made very strong impressions on his coaches this spring and will be in the rotation inside.

4. Florida: This unit was criticized for lacking toughness last season, but will be full of that and even more athleticism in 2011. Jaye Howard is returning from spring ankle surgery and is already considered a top defensive tackle prospect in next year’s NFL draft. Alongside him are youngsters Sharrif Floyd and Dominique Easley. Floyd was the most consistent of the much-ballyhooed freshman class last fall, while Easley struggled with attitude problems. Easley has rebounded and both excelled this spring. Omar Hunter is finally healthy and will share time with Floyd at noseguard and senior William Green will occupy an end spot. This group is even better when Ronald Powell lines up at end in the 4-3.

5. Alabama: On paper, there are a few questions with this group, but it’s hard to drop Alabama very far on this list. The 3-4 scheme will have senior Josh Chapman at noseguard. Chapman started 12 games in the middle last fall, totaling 31 tackles, including 3.5 for loss. Damion Square will compete for time on the outside, and since returning from his ACL injury, he’s gained a lot more playing confidence and could be a budding star in the league. Junior college transfers Quinton Dial and Jesse Williams will compete for time on the line as well, while sophomore Ed Stinson will stay at end after starting last season at Jack linebacker.

6. Mississippi State: The Bulldogs have arguably the top returning tackle tandem in the SEC. Fletcher Cox and Josh Boyd are the behemoths in the middle who combined for 53 tackles, 13 for loss and five sacks last year. Finding any sort of inside running game against Mississippi State will be extremely tough. Developing a pass-rusher is the next step for the Bulldogs’ staff. Sean Ferguson occupies one side, but the other is still up for grabs. Trevor Stigers and Shane McCardell battled for the spot this spring, but neither has really pushed ahead.

7. Georgia: There is a lot of talent in Athens, but there could be a lot of movement on the line. JUCO transfer John Jenkins is the big -- and we mean big -- name up front and he’s yet to play a down in the SEC. He arrives with a ton of hype, but is perfect at noseguard in Todd Grantham’s 3-4. DeAngelo Tyson moves to his natural position outside after playing noseguard last year. Kwame Geathers played in the middle this spring, but could be usurped for Jenkins this fall and move outside. Abry Jones is still maturing after moving to end and recording 34 tackles including 3.5 for loss last season and had a 16-tackle performance against Georgia Tech.

8. Auburn: The Tigers must replace three starters this season. Inside, Auburn is talented but inexperienced with Kenneth Carter and Jeffrey Whitaker having 13 combined tackles from a year ago. There’s less concern on the outside with lone returning starter Nosa Eguae on one side and sophomore Corey Lemonier on the other. Eguae might have more experience with 11 starts, but Lemonier appears to be more athletic and should be near the top of the defensive end pool this year. After that, the Tigers are young across the board.

9. Tennessee: The Volunteers’ line will grow with senior Malik Jackson running things in the middle. He had 48 tackles and five sacks a year ago and some think he’ll be even better this fall. A lot will also be expected from incoming JUCO transfer Maurice Couch. He’s pretty athletic at 6-foot-4, 327 pounds and he’ll be greatly needed, considering the dismissal of Montori Hughes. Jacques Smith has All-SEC potential and will hold one of the end spots. After that, Tennessee has some young, but encouragingly talented bodies at each position.

10. Ole Miss: Some of the best news of the spring coming out of Oxford was the return of Kentrell Lockett at defensive end. Lockett was granted an extra year of eligibility by the NCAA and will not only be the Rebels’ top lineman but possibly their best defensive player. After that, the questions roll in with four tackles gone and youth coming in. Tackle Justin Smith has yet to really emerge as the All-SEC talent he was expected to be and Ole Miss is smaller up front. JUCO transfer Gilbert Pena could add some size in the middle. Gerald Rivers returns to get time at end, but has played in just 15 career games in two years.

11. Vanderbilt: This was supposed to be a strength for the Commodores last year until injuries hit. Still, Vanderbilt returns three starters. Experience is there, but this unit has to continue to improve, especially in the pass-rushing department where the Commodores had just 20 sacks in 2010. Rob Lohr led Vanderbilt with four sacks a year ago and had 35 tackles. T.J. Greenstone is coming off of injury and will line up inside. Tim Fugger was one of the Commodores' most consistent players at end, playing in every game and registering three sacks and four forced fumbles.

12. Kentucky: End Collins Ukwu and tackle Luke McDermott return with the most experience on Kentucky’s line. Ukwu improved not only on the field but in the weight room this spring and is expected to be a more consistent pass-rusher. McDermott is a walk-on currently ahead of Donte Rumph, who has the talent to be one of Kentucky’s top defenders, but has yet to fully buy in to the program. The coaches are also waiting for tackle Mister Cobble to finally break out of his funk and be a regular contributor. The rest of Kentucky’s linemen have some developing to do and are inexperienced.
