Alabama Crimson Tide

Alabama might have fallen to No. 2 in ESPN colleague Mark Schlabach's Way-Too-Early Preseason Top 25, but I'd like to think that most of the college football world still considers the Crimson Tide to be the favorites to win the national championship again.

Alabama lost nine draft picks, including three first-rounders, but Nick Saban has a host of talent returning on both sides of the ball, and the Tide's schedule isn't too daunting after the first two games.

But there are teams that will test the Tide's road to a national championship trifecta in 2013. Colleague Travis Haney picked five teams from around the country that could challenge Alabama's title hopes this fall. Ohio State topped his list, while Texas A&M made it from the SEC.

No surprise there with the Aggies. Heisman Trophy winner Johnny Manziel returns with a bundle of riches to accompany him in the Aggies' backfield.

Johnny Football might not have Luke Joeckel protecting him, but Jake Matthews provides quite the safety net with his move to left tackle, and there is still talent and experience up front. Mike Evans leads a young but talented group of pass-catchers.

The defense is a concern, with five members of last season's front seven gone, but the Aggies will still be equipped to win most shootouts.

A&M benefits from getting Alabama at home early in the season, but has to play Arkansas, Ole Miss, LSU and Missouri on the road. Even beating Alabama early doesn't guarantee the Aggies will make it to Atlanta over the Tide.

Here are four other SEC teams that could wreck Alabama's title train this fall:

Florida

The Gators will yet again be elite on defense. First-round draft picks Sharrif Floyd and Matt Elam might be gone, but Dominique Easley moves back to his more natural position at defensive tackle and could one of the best at his position this fall. Marcus Roberson and Loucheiz Purifoy could be the top cornerback duo in the SEC, while inside linebacker Antonio Morrison has the makings of being a budding star.

The offense is still a concern, especially with the lack of proven receiving talent, but quarterback Jeff Driskel has found a lot more confidence in his second year under offensive coordinator Brent Pease, and he'll have a much tougher offensive line and another loaded backfield to work with.

Georgia

Sure, the defense is younger and less experienced, but people in Athens are excited about the younger guys taking over. They were very receptive to coaching and showed continued improvement this spring. Linebacker Jordan Jenkins has playmaker written all over him, while freshman Tray Matthews could be the next big thing at safety. Having Damian Swann back at cornerback is huge.

Offensively, Georgia will be able to score on just about everyone. Aaron Murray is looking to be the first SEC quarterback to throw for 3,000 yards in four seasons, and should leave with a handful of SEC/Georgia records. He has five offensive linemen returning, the best one-two running back punch (Todd Gurley and Keith Marshall) and plenty of receivers to throw to, including Malcolm Mitchell, who has moved back to offense full-time.

LSU

Yes, the Tigers lost a ton of talent on the defensive side of the ball, but Les Miles seemed pretty happy with where his defense was -- especially his defensive line -- at the end of spring. Jermauria Rasco could be a big-time player at defensive end for LSU, while linebacker Lamin Barrow has the talent to be an All-SEC performer. The return of cornerbacks Jalen Collins and Jalen Mills should continue the Tigers' trend of having an elite secondary.

The offense should be better, too. Zach Mettenberger is way more comfortable in the offense and has developed better chemistry with his receiving targets, which all return from last season. He'll have a solid offensive line in front of him and a loaded backfield. Although, it will be important to see what happens to the suspended Jeremy Hill, who could be the Tigers' top offensive weapon.

South Carolina

Jadeveon Clowney hasn't left, and the Gamecocks should once again be stacked along their defensive line. South Carolina does have to replace its two-deep at linebacker and has a couple of holes in its secondary, but we all know that a good defensive line can mask weaknesses behind it.

And the offense should be pretty balanced this fall. South Carolina possesses two solid quarterbacks and a talented running back stable led by rising sophomore Mike Davis. Bruce Ellington is back at receiver, and it sounds like the very talented Shaq Roland is finally starting to come around and should be a valuable receiving target this fall. This team has the personnel to make it back to Atlanta.
