Editor's note: This is Part IV in a weeklong series looking at the five most pressing concerns Alabama faces this offseason.

TUSCALOOSA, Ala. -- The body of evidence is compelling. Alabama, after years of defensive dominance, has a problem with the hurry-up, no-huddle offense.

Nick Saban can't avoid it any longer. After an offseason spent agonizing over offenses like Texas A&M's, he and defensive coordinator Kirby Smart came up empty. Alabama gave up the most yards in school history to Texas A&M this past season and followed that up with a poor performance against Auburn in the Iron Bowl and a disastrous showing against Oklahoma in the Allstate Sugar Bowl.

It's time to change. Or at least make significant tweaks.

Alabama's defense won't be the same next season. Three-quarters of the secondary will be gone and more than half of the front seven will be out the door as well. Greg Brown won't be coaching the secondary and Chris Rumph won't be coaching the defensive line any longer. That kind of large-scale turnover can be viewed as a negative or a positive. The silver lining for Saban is that he has a chance to start fresh.

"If you continue to do what you have been doing, you will continue to get the same results," Saban told the audience at the annual American Football Coaches Association conference in Indianapolis this week.

Continuing to get outflanked by the spread, outmatched by mobile quarterbacks and outwitted by uptempo offenses can't be the answer. Saban's defense has a strong track record, but adjustments must be made for success in the long term. There's simply too much football knowledge among Alabama's coaches to not adapt and overcome.

"All you're trying to do is get lined up [on defense]," Saban said of facing uptempo offenses in late September. "You can't play specialty third-down stuff. You can't hardly scheme anything. The most important thing is to get the call so the guys can get lined up, and it's got to be a simple call. The offense kind of knows what you're doing."

Corralling new-age offenses is a big task, one that no coach in college football has really mastered. But for Alabama's dynasty to be revived in 2014, tackling those kinds of scheme must happen. Teams like Texas A&M and Auburn aren't going away. Nick Marshall will be back under center for the Tigers next season, Ole Miss will continue to push the tempo under coach Hugh Freeze and even Mississippi State will look to beat the Tide with a spread offense and an athletic quarterback in Dak Prescott. West Virginia has run the spread for years, Tennessee's Butch Jones runs a version of it and even Florida coach Will Muschamp says the Gators are going that way too.

While the spread, uptempo offenses were a unique challenge a few years ago, next season they'll be more of the norm with at least seven of Alabama's 12 scheduled opponents featuring some form of the increasingly popular scheme.

Getting more athletic up front on defense seems to be a significant part of the answer for Alabama. With true freshmen like A'Shawn Robinson and Jonathan Allen emerging as dangerous pass-rushers, that's a good place to start. The return of D.J. Pettway should help, as should the eventual arrival of five-star commitment Da'Shawn Hand.

Matching athleticism with athleticism will go a long way, but the staff will have to do more to confront its most glaring weakness. Trey DePriest will have to take on a more influential leadership role with C.J. Molsey gone, and the back end of the defense will need to improve as well.

One offseason wasn't enough to solve the hurry-up no-huddle conundrum. The hope for Alabama fans is that with one more offseason to prepare, a few more staff changes and some better personnel, the problem won't be so pronounced.
