ESPN College Football

Schedule: Texas A&M opens spring practice on Saturday and will play its Maroon & White spring game on April 28 at 2 p.m. ET. The Aggies will give fans a couple of chance to see open scrimmages prior to the spring game. Fans are invited to the April 14 scrimmage at 11 a.m. and the April 20 scrimmage at 8 p.m.

What’s new: Really, just about everything. The Aggies will begin play in the SEC in 2012, and Kevin Sumlin takes over as head coach after spending the last four seasons as Houston’s head coach. Sumlin worked under R.C. Slocum at Texas A&M in 2001 and 2002 and called the Aggies’ plays for most of the 2002 season. Sumlin’s offensive coordinator and quarterbacks coach will be Kliff Kingsbury, a record-setting quarterback during his time at Texas Tech. Clarence McKinney will coach the running backs and serve as recruiting coordinator, and B.J. Anderson will coach the offensive line. Kingsbury, McKinney and Anderson were all with Sumlin last season at Houston. David Beaty will coach receivers after serving as Kansas’ co-offensive coordinator last season. Brian Polian, who was previously at Stanford, will coach tight ends and oversee special teams. Former Marshall head coach Mark Snyder will be the Aggies’ defensive coordinator. Snyder was the defensive coordinator at South Florida the past two seasons and also served under Jim Tressel at Ohio State. Marcel Yates will be the co-defensive coordinator and secondary coach after spending the last nine seasons coaching defensive backs at Boise State. Former Texas A&M player Terry Price will coach the defensive line. He was previously on the Ole Miss staff. Matt Wallerstedt will coach the Texas A&M linebackers after serving as associate head coach, defensive coordinator and linebackers coach at Air Force the past two seasons.

On the mend: Senior running back Christine Michael, who tore his left ACL toward the end of last season, is ahead of schedule in his recovery, but the Aggies won’t chance it with any contact this spring.

On the move: Junior Damontre Moore, who had 17.5 tackles for loss as the “joker” linebacker in the Aggies’ 3-4 scheme last season, is moving to defensive end in their new 4-3 defense. Also, the Aggies may not have running back Brandon Williams, who transferred from Oklahoma. Williams is a former five-star recruit, but his appeal to the NCAA to be eligible in 2012 was reportedly denied, and he’ll have to sit out the season. Texas A&M officials said Friday, however, that they have yet to send anything to the NCAA on Williams' behalf and are in the process of putting something together.

Key battle: With Ryan Tannehill taking his talents to the NFL, the Aggies hope to settle on a new quarterback this spring. It could take longer, as nobody has any real experience. Third-year sophomore Jameill Showers played in four games last season and threw all of five passes in mop-up duty. He’s the “veteran” of the group. Redshirt freshman Johnny Manziel might be the most dynamic athlete of the bunch, and Kingsbury also likes the way midterm enrollee Matt Davis can move around and make plays. Sophomore Matt Joeckel is more of a pocket passer. Kingsbury said all four have their strengths and do different things well, which should make for a close race.

New faces: Being on campus early and going through spring practice will give Davis a legitimate chance to win the starting quarterback job as a freshman. Defensive back Kenneth Marshall of South Houston, Texas, also graduated high school early and will go through the spring. Derel Walker of Trinity Valley Community College was rated among the top junior-college receivers nationally. Cornerback Tremaine Jacobs is another junior-college newcomer who’s enrolled and will go through the spring. Jacobs is from Mississippi Gulf Coast Community College.

Breaking out: Even with Moore moving to defensive end, the Aggies have a chance to make a big splash at linebacker. There’s already a buzz surrounding senior Jonathan Stewart and his move to middle linebacker. He led the Aggies with 98 total tackles last season, including 55 solo stops. He’s had a terrific offseason, and by all accounts, is poised for a big senior season. It only helps that he’ll have fellow senior Sean Porter playing alongside him at outside linebacker. Porter led the Aggies with 9.5 sacks last season and racked up 17 tackles for loss.

Don’t forget about: One of Sumlin’s biggest coups this offseason was convincing star receiver Ryan Swope to return for his senior season. Sumlin got a big assist from Kingsbury, who painted an enticing picture of what Swope’s role would be in this new offense. Swope was third in the Big 12 last season in both receptions (89) and receiving yards (1,207). He also caught 11 touchdown passes and will be key player in keeping opposing defenses from loading up against the Aggies’ running game.

All eyes on: What will the offense look like? Chances are that it won’t be quite as much of an “Air Raid” attack it was in Houston. Sumlin is always going to utilize the passing game, but the strength of this team will be the offensive line. Tackles Luke Joeckel and Jake Matthews are future pros, and senior Patrick Lewis also proved to be a devastating blocker at center after moving over from right guard. The Aggies will lean heavily on their offensive line, which has a chance to be one of the top units in the SEC.

It's Moving Day No. 2 on the blog network today, and the Aggies are following Missouri out the door into the SEC blog. We introduced the Aggies to the SEC earlier, but now it's time to debate.

The Aggies' move to the SEC was more about having the program grow in new soil, whereas Missouri's move was more about conference stability.

Will the Aggies thrive? SEC blogger Chris Low and Big 12 blogger David Ubben go head-to-head to find out.

Chris Low: OK, David, let's not tiptoe around. The SEC is a big-boy conference with big-boy stakes. I know everything is supposedly bigger in Texas, but do the Aggies really know what they're getting themselves into? For one, they tend to play all four quarters in the SEC. Judging by what I saw from the Aggies last season, somebody might want to remind them that there is a second half. Come to think of it, that's not very hospitable of me. I take that back. But, honestly, how do you think the Aggies will handle the grind of this league?

David Ubben: Now, now, Chris, that's not very nice. The Aggies are ...

As one final tribute to Texas A&M, I elected to forfeit the second half of that sentence.

In the early running, Texas A&M will have a lot of issues. Losing the volume and quality of talent it did in 2011 will hurt, especially on offense, as the program moves into a league -- and, particularly, a division -- known for defense. Ryan Tannehill wasn't great last year, but his experience helped, and Jeff Fuller and Cyrus Gray are a pair of NFL players who don't roll around every year.

I like the talent on campus at A&M a lot, though. They're just going to be young for now. With what they have now, they'll get better and better, as long as Kevin Sumlin does well. Based on what we've seen from his career, I think he will.

Beyond these first three to four years, how well they progress will depend on recruiting. The Aggies think the SEC will be a big draw for Texas recruits who want to play in the best conference in college football. Being able to offer that could help them surpass Texas on the recruiting trail and on the field.

Are you buying that? I lean strongly toward no, but I could see it happening. What do you think? Is playing in the SEC going to be a draw for Texas kids? Why or why not?

CL: I absolutely think the SEC will be a draw for some Texas recruits who see it as a chance to stay in the state, still play their college football and be able to do it against SEC competition. That's a pretty sweet proposition: Stay close to home in the football-crazed state of Texas and compete in the football-crazed SEC, which has a standing order with the sculptor who designs that crystal trophy every year for the BCS national champion.

There's also another side to this story. The boys in the SEC think their chances of going deep into the heart of Texas and landing elite prospects are better than ever with Texas A&M joining the league. Rival coaches can tell mamas and daddies (that's the way the Bear used to say it) that they'll be able to keep up with their sons just as they were in the Big 12 with the Aggies now part of the SEC family, although the recruiting atmosphere in this league isn't very family-oriented. Just ask Urban Meyer. He got so tired of the recruiting shenanigans in the SEC that he's now pulling his own in the Big Ten, according to some of his new brethren there.

That leads me to my next question: Has anybody informed the Aggies that the rules are a little different in the SEC? Unlike the Big 12, it's not the first team to 40 points that wins.

DU: For the record, the league changed those rules for Baylor-Washington in the Alamo Bowl. First to 60 points wins now, but that's irrelevant news for the Aggies.

A&M's front seven has been really good these past two years, but this season, it was the secondary that let the team down. The Aggies led the nation with 51 sacks, but the team wasn't happy that it took a lot of risky blitzes to get those sacks. The defensive line wasn't the unit applying the pressure most often -- it was linebackers and defensive backs. That meant a lot of big plays in the passing game; the Aggies ranked 109th nationally in pass defense, giving up more than 275 yards a game. Now, they won't see the same caliber of quarterbacks in the SEC, but we will see if the front seven can handle the power of teams in the SEC West, which, to their credit, do have a handful of quarterbacks with a lot of potential. Tyler Wilson's great now. AJ McCarron and Kiehl Frazier could be elite soon.

We'll see what new defensive coordinator Mark Snyder can fix.

On the flip side of the recruiting debate, how much do you think SEC teams will try and slide into Texas? Could we see some collateral damage in the Big 12? Will the SEC someday take over the world? I heard Nicolas Sarkozy already has a special security detail in place in case Mike Slive comes after him.

CL: I'm not sure about taking over the world. It's just college football that the SEC someday would like to own. Some might suggest it already does.

Arkansas and LSU probably will be helped the most in terms of going into Texas and getting players. Other schools in the SEC might be more apt to target players in the state of Texas and make a push for those select players, but I don't think you're going to suddenly see a mass of teams in the SEC setting up camp in Texas on the recruiting trail. There's no need to when you look at how bountiful the states of Florida, Georgia, Alabama, Louisiana and South Carolina are in most years.

You mention some of the quarterbacks in the Western Division. It's fair to say that this wasn't a quarterback's league this season, and I also realize that the Big 12 has produced some quarterbacks over the last few years who've put up Xbox-type numbers.

But my question for you: Is Texas A&M capable of playing the kind of defense it takes to win big in the SEC?

DU: I think so, eventually. The Aggies know they have to, which is huge. They've seen how teams succeed in the SEC, and it's with defense.

If you invest in something, especially with the resources A&M has, good things will happen. Don't forget, the Aggies' defense was really, really good last year. The athletes are there. For A&M, it's about putting it together.

CL: With all due respect, "really, really good" on defense in the Big 12 is entirely different than being "really, really good" in the SEC on defense. The more I watch this conference, the more it's ingrained in me that you're never going to win at a high level unless you can run the ball, stop the run and consistently win the turnover battle. Everything else is window dressing. I understand that's not exactly rocket science, but being able to run the ball creates a mindset that positively impacts your entire team. The same goes for playing good run defense.

So if I were offering any advice to the Aggies as they make the big jump, it would be to fortify their offensive backfield and recruit like crazy in the offensive and defensive lines. There's no such thing as too much depth in the SEC.

Having a little Texas flavor in the SEC is exciting. I know you're on record as saying the Aggies might struggle next season. But over time, I think they have what it takes to be an upper-echelon team in the SEC. Of course, that's the beauty of the SEC. So does everybody else in the league.

DU: Oh, there's no respect due when we're talking Big 12 defenses. The best in the SEC are on another stratosphere from the best in the Big 12.

Your game plan sounds like what I'd recommend, but it's easier said than done. Like Mizzou, A&M will have to start mining some of those junior colleges down South like the rest of the SEC West.

Generally, I'd agree with you on A&M's long-term prospects. The Aggies will win less than they did in the Big 12 ... which is to say not much. But they could put it together and have a huge year every now and then. I don't see them surpassing Texas as a program, but they're on their own now.

For some Aggies, that's enough. Next year, the Aggies will struggle, but watching them grow and try to build a new program will be fascinating.
