David Helman writes : The home stretch for the NFL draft begins in earnest Thursday for LSU alums, as the Tigers prepare for their annual pro day.

We move to linebackers today in our postseason position rankings.

Defensive lines are very important in this league, but there are other guys in the box who have to be pretty reliable as well in this league. This league has done a pretty solid job of producing some top talent at this position as well.

You can see what are preseason linebacker rankings looked like here.

And here are our postseason rankings:

1. Alabama: This unit was at the top of our preseason rankings and didn't budge throughout the season. When you have two All-Americans in Courtney Upshaw, who was the defensive MVP in the Allstate BCS National Championship Game, and Dont'a Hightower it's pretty understandable to see why. Those two combined for 136 tackles, including 29 for loss. Nico Johnson was fourth on the team in tackles, while C.J. Mosley added 37 of his own. Alabama's defense was first nationally in total defense and first in rushing defense, allowing 74.2 yards per game.

2. Georgia: Linebackers are essential to any 3-4 defense, and the Bulldogs' group did quite well in 2011. Georgia ended up with one of the nation's best linebackers in Jarvis Jones, who led the SEC with 19 tackles for loss and 13.5 sacks. He also had 49 quarterback hurries. Michael Gilliard was third on the team behind Jones with 65 tackles. While Alec Ogletree missed part of the first half of the season, the speedster still finished with 52 tackles, including 7.5 for loss. Cornelius Washington, Amarlo Herrera Christian Robinson combined to add 101 more tackles, as Georgia's defense ranked fifth nationally.

3. Arkansas: Arkansas' defense had a lot of bend in it last season, but the linebackers found ways to make plays. Newcomer Alonzo Highsmith was third on the team with 80 tackles, led with 12.5 tackles for loss and had 4.5 sacks. The star continued to be Jerry Franklin, who led the team in tackles (101) for the fourth straight year. Then there was Jerico Nelson, who was all over the field as that hybrid linebacker/safety. He came away with 70 tackles, two sacks and two interceptions. Ross Rasner, who played outside with Nelson, added 53 more tackles and two sacks.

4. Florida: The Gators' defense ranked eighth nationally in part because of the aggressive play of its front seven. Jon Bostic commanded the middle, leading the team with 94 tackles, including 10 for loss. Jelani Jenkins seemed to come more into his own outside, finishing third on the team in tackles. The big surprise was Lerentee McCray, who played both Sam linebacker and the hybrid Buck. He was one of Florida's most active linebackers and grabbed 7.5 tackles for loss. Ronald Powell started at the Buck, but saw most of his production from defensive end.

5. Vanderbilt: The Commodores entered the season needing to replace three starting linebackers and ended the year with a very impressive linebacking corps. It was led by vet Chris Marve, who was 10th in the league in tackles. Archibald Barnes had a solid year at the Will, ranking fourth on the team in tackles and grabbing two interceptions. Chase Garnham and Al Owens manned the Sam position and combined for 72 tackles and 7.5 tackles for loss. Against conference foes, Vandy's rush defense ranked fourth in the league.

6. LSU: The Tigers were in search of that dominant middle linebacker all season and might have found a budding star in Kevin Minter, really grew into the position by the end of the season and was fifth on the team in tackles. He started 11 games, but shared time with Karnell Hatcher, who finished with 24 tackles. Ryan Baker was LSU's best linebacker, was an outstanding leader and was fourth on the team with 64 tackles. Stefoin Francois was the starter at Sam, but he accumulated just 11 tackles, while backup Tahj Jones registered 27. Still, LSU owned the No. 2 national defense.

7. South Carolina: The Gamecocks saw improvement from this group as the season went on. While the defensive line got a ton of credit, the linebackers did their part in securing the defense's No. 3 national ranking. Antonio Allen spent some time in the box at the Spur position and led South Carolina with 88 tackles and had 9.5 for loss. Rodney Paulk and Shaq Wilson, who returned from injury, rotated at the Mike and combined for 109 tackles. Will linebacker Reginald Bowens added 44 tackles.

8. Kentucky: The Wildcats owned the SEC's top tackler in Danny Trevathan (143), who should have received more national attention. Trevathan was one of the most active defenders around at the Will. Winston Guy played the hybrid linebacker/safety and was third in the SEC with 120 tackles. Ronnie Sneed added 71 more tackles. Kentucky's defense was much more aggressive under new defensive coordinator Rick Minter and got more exotic looks from its linebackers.

9. Mississippi State: Cameron Lawrence was a beast for the Bulldogs in 2011. He was second in the SEC with 123 tackles, and had 49 solo. Senior Brandon Wilson added 94 more tackles. Brandon Maye, who transferred from Clemson, was expected to make a bigger impact for the Bulldogs, but played behind Wilson and was 11th on the team in tackles. Sophomore Deontae Skinner added 69 tackles and Mississippi State ranked in the bottom half of the SEC in total defense.

10. Tennessee: The Vols' top three tacklers were linebackers. The leader was senior Austin Johnson, who finished the season with 81 tackles, including 41 solo. Next were two true freshmen on the outside in A.J. Johnson (80) and Curt Maggitt (56). Both freshmen experienced up-and-down seasons, but were SEC All-Freshman selections. Herman Lathers, who was a projected started, missed 2011 with a fractured ankle, and after the big three, the Vols didn't get a ton out of their linebackers, as Dontavis Sapp was their next most productive linebacker with 20 tackles.

11. Auburn: The Tigers' defense really struggled in 2011 and gave up more than 200 rushing yards a contest. Auburn had to basically start over at linebacker, but lone returning starter Daren Bates had a heck of a year, ranking fourth in the league with 104 tackles. He really tried to make sure he played all over the field last fall. After that, the play was up-and-down. Senior Eltoro Freeman took over in the middle halfway into the year and finished with 58 tackles, while Jake Holland and Jonathan Evans combined for 83 tackles.


12. Ole Miss: The Rebels' defense had all sorts of problems defensively, including allowing 256.5 yards per game and 21 rushing touchdowns. The linebackers took a major hit with the absence of D.T. Shackelford, who missed the season with a knee injury. Mike Marry stepped up at the Mike and led Ole Miss with 81 tackles and five for loss. Freshman Serderius Bryant and junior Joel Kight combined for 122 tackles. Damien Jackson played the Spur and added 64 tackles, but Ole Miss' defense ranked dead last in the SEC.

The Tigers enter the 2011 season with some of the best defensive talent in the country:

Biggest reason for hope: Talented defense and The Hat

LSU's defense might be a bit young, but it could be the most athletic in the country. Cornerbacks Morris Claiborne and Tyrann Mathieu showed that they each have the ability to make big plays in the secondary now that Patrick Peterson is gone. Senior safety Brandon Taylor should be a force in the defensive backfield as well. Linebackers Ryan Baker and Stefoin Francois look like they'll be be even better this fall. On the defensive line, Sam Montgomery is coming back from injury at defensive end and if he's totally healthy, he'll be chore for opposing tackles to handle. Newcomer Anthony Johnson had a really solid spring at defensive tackle and should contribute this fall. But more than anything, Les Miles has Lady Luck on his side. Toss in some mighty tasty grass, and Miles is in hog Heaven (or Tiger Heaven). The way he defied logic to win games last season amazed everyone and I'm not sure his luck has run out.

Biggest reason for concern: Quarterback and middle linebacker

Jordan Jefferson might have directed the offense more smoothly and improved his passing mechanics, but we need to see how he does against players not wearing purple and gold. Jefferson was one of the worst statistical passers in the SEC a season ago, but somehow managed 11 wins. This season, a slip up by Jefferson will leave Miles contemplating benching his senior for transfer Zach Mettenberger, who is probably the best pure passing option the Tigers have. However, Mettenberger doesn't have the experience Jefferson does. The Tigers also have a gaping hole at middle linebacker now that Kelvin Sheppard is gone. Safety Karnell Hatcher and Kevin Minter, who was Sheppard's backup last year, got reps at middle linebacker this spring, but the spot has yet to be solidified, which has LSU's coaching staff a little worried heading into summer.
