The Aggies' season will hinge on quarterback Johnny Manziel's eligibility.
Biggest games in 2013: vs. Alabama (Sept. 14), at Ole Miss (Oct. 12), vs. Vanderbilt (Oct. 26), at LSU (Nov. 23)
Biggest question mark heading into 2013: As of Monday, it is the status of quarterback Johnny Manziel. News broke Sunday of an NCAA investigation of Manziel, the reigning Heisman Trophy winner, about whether he accepted payment for signing autographs. There's concern whether his eligibility for the upcoming season will be affected. If it is, the Aggies would have to turn to either junior Matt Joeckel or redshirt freshman Matt Davis at quarterback. If no wrongdoing is found, the expectations will be high for the Aggies.
Forecast: If Manziel is cleared of any wrongdoing in the NCAA investigation, then the Aggies are legitimate SEC West, SEC Championship and perhaps BCS Championship contenders. They'll likely be favored in every game except their home matchup against Alabama on Sept. 14 and perhaps a road game at LSU on Nov. 23, one of the two teams they lost to a year ago.
Aside from Manziel, the biggest on-field questions for the Aggies are on defense. Three of their most productive players from 2012 -- defensive end Damontre Moore and linebackers Sean Porter and Jonathan Stewart -- are now in the NFL. The Aggies are young and inexperienced in the front seven and the status of two starting defensive backs (cornerback Deshazor Everett and safety Floyd Raven) must be determined after offseason arrests.
Still, with the return of Manziel, leading receiver Mike Evans and three offensive linemen, the Aggies have the offensive personnel to compete with any team in the country. They proved as much in their upset of eventual national champion Alabama in Tuscaloosa, Ala., last season. If the defense can make the kind of strides it did a season ago, when the Aggies had depth questions across the defense and concern about size up front in a line-of-scrimmage league, then Texas A&M can seriously contend.
If Manziel's eligibility is affected as a result of the NCAA investigation, the Aggies have no quarterback on the roster who has started a college game. Joeckel and Davis will battle it out in training camp. While the Aggies can be a good team without Manziel, dreams of reaching the highest heights will be severely damaged if Manziel is forced to miss more than two games.
