We all know that defense wins championships and the SEC is very much a testament to that. Alabama possessed the nation's No. 1 defense last season and now possesses another national championship. Runner-up LSU ranked second nationally.
Alabama ran away with the crown as the nation's and the SEC's best defense, but that title is for the taking in 2012. Alabama is down key players from last year's squad, like linebackers Courtney Upshaw and Dont'a Hightower, defensive tackle Josh Chapman, and defensive backs Mark Barron, Dre Kirkpatrick, and DeQuan Menzie.
Alabama's defense isn't as green as the 2010 group, but it's still drawing some comparisons to it. That's exactly what the Tide wants to hear. Nico Johnson seems primed to be a true leader at linebacker, while Adrian Hubbard could be a budding star at Upshaw's old position. Defensive backs Robert Lester and Dee Milliner are back and will be joined by a couple of JUCO standouts and talented sophomores Vinnie Sunseri and Ha'Sean Clinton-Dix. Jesse Williams could be a real force at defensive tackle along with end Damion Square.
Then you have LSU. The Tigers lost All-World cornerback Morris Claiborne to the NFL draft and two starting linebackers. Michael Brockers is gone at defensive tackle as well. But LSU is still loaded. The Tigers return Heisman finalist Tyrann Mathieu and Tharold Simon, who should be fine with an expanded role at cornerback. Junior Kevin Minter really stepped up at linebacker last year and should pick up right where he left off. Even without Brockers, the line is solid with future first-rounder Sam Montgomery at one end position and the underrated Barkevious Mingo at the other. The two combined for 17 sacks last season.
Georgia and South Carolina both finished the 2011 season ranked in the top five nationally in total defense. South Carolina was third, while Georgia was fifth, respectively. The Gamecocks lost first-round defensive end Melvin Ingram, but return freshman standout Jadeveon Clowney and Devin Taylor, who many thought would be better than Ingram last season. Kelcy Quarles is back at defensive tackle and the coaches think he'll be even better in his second year.
Shaq Wilson and Reginald Bowens, who combined for 96 tackles last year, will grab time at linebacker again, while the very athletic DeVonte Holloman returns to the Spur for his senior year. There are questions in the secondary, but seniors D.J. Swearinger (safety) and Akeem Auguste (cornerback) return.
Georgia returns nine defensive starters. Brandon Boykin is gone at corner, and the Bulldogs will enter the fall with a lot questions in the secondary, especially with starters Branden Smith, Sanders Commings and Bacarri Rambo suspended to start the season. Star freshman receiver Malcolm Mitchell moved to corner this spring and fits right in, but there are depth issues at the position.
Other than that, the Bulldogs are still pretty stacked. Inside linebacker Alec Ogletree will serve a suspension to start the year, but Georgia will fill his spot by committee. Mike Gilliard, Cornelius Washington, Christian Robinson, Amarlo Herrera and Ramik Wilson provide Georgia with a very solid linebacking unit alongside star Jarvis Jones, who racked up 19.5 tackles for loss and 13.5 sacks. Georgia's defensive line should also be pretty stout with the massive John Jenkins and Kwame Geathers battling in the middle. Abry Jones really progressed at end as well this spring.
Or maybe someone else will step up and take the crown ...
