With so much quarterback talent leaving the SEC after the 2013 season, it seems nearly impossible for the league's offenses to maintain their production from a year ago. There is simply too much to replace at the game's most important position to predict that SEC offenses won't experience at least a temporary efficiency gap.
Last fall featured a collection of some of the most productive SEC players who ever lined up under center -- led by 2012 Heisman Trophy winner Johnny Manziel, 2013 Heisman runner-up AJ McCarron and the league's all-time leading passer Aaron Murray. Throw in South Carolina's Connor Shaw, LSU's Zach Mettenberger, Missouri's James Franklin and Vanderbilt's Austyn Carta-Samuels, and you have veterans who posted eye-popping numbers or who helped their teams ascend to rarely-seen heights in their respective programs' histories.
They're all gone now, leaving offensive coordinators at some of the league's most prominent programs to start over with new quarterbacks -- and in some cases, quarterbacks who haven't started a single game.
That has to help the league's defensive coaching staffs feel a bit more confident despite the thrashings their units absorbed over the last year or two, but I've got some bad news for them. Their problems are far from solved.
The last couple of seasons only continued a trend toward more explosive offense and away from the suffocating defense that was the SEC's trademark for many years. Just a few seasons ago, nearly every SEC defense ranked among the nation's top half in terms of yards allowed. That's no longer the case, as about half of the league's defenses trended toward the bottom in 2013 -- with Arkansas (76th), Missouri (81st), Tennessee (83rd), Auburn (86th), Kentucky (91st) and Texas A&M (109th) all ranking 75th or worse nationally in total defense.
Getting rid of some great quarterbacks will certainly help improve those numbers, but this is no longer the smashmouth, pound-the-run league that it once was. It's not as simple to defend what today's offenses throw at you as it was during the I-formation days of yore, and several SEC defenses have a long way to go before anyone would consider them competent at containing such attacks.
You have Gus Malzahn's ground-based spread at Auburn, which led the nation with 328.3 rushing yards per game and nearly carried the Tigers to a BCS crown. There's Missouri's version that featured one of the league's top rushing attacks and some dangerous (and huge) weapons at wideout. Kevin Sumlin's spread at Texas A&M obviously benefited from having Manziel as the triggerman, but the Aggies are still going to post big numbers even without Johnny Football.
And you've still got versatile offensive schemes such as those at Ole Miss, South Carolina and Georgia -- all of which will start senior quarterbacks -- that will almost certainly continue to produce on the ground and through the air. Wild cards LSU, Florida and Mississippi State also have the potential to be impressive on offense depending on how their quarterbacks and young skill players develop.
Add it all up and it still looks like 2014 will still be a promising year for SEC offenses, even if it might not match the production from a period that featured some of the league's best quarterback talent in at least a generation.
That said, the league will still have its share of defensive stalwarts, and that group might even grow a bit larger this fall.
Alabama's defense is always one of the best, and a talented Florida team should take a step forward after injuries crippled it a season ago. South Carolina, LSU and Mississippi State all look to be impressive, while Georgia returns most of its starters and scored points in convincing Jeremy Pruitt to defect from Florida State to become its new defensive coordinator.
Those groups should be fine. If the league is to recover some of its defensive reputation, however, it will be a matter of the league's worst defenses suddenly getting their acts together -- and that will be a tall order since some of them were truly awful last season.
So to answer the original question, will SEC defenses improve this season? Sure, but don't expect a defensive renaissance to occur anytime soon. As long as the league features this many innovative offensive minds and explosive playmakers, the days where most SEC teams dominated the national defensive rankings are not coming back.
