Strong and weak: Texas A&M

It’s time to check out Texas A&M's strongest position and weakest position heading into the 2013 season.

Strongest position: Running back

Texas A&M coach Kevin Sumlin is pumped about his depth at running back. But even more so, he's excited about all the different things the Aggies should be able to do with their backs. Christine Michael departed, but dependable Ben Malena returns after leading all running backs on the team with 808 rushing yards last season and averaging 5.9 yards per carry. Oklahoma transfer Brandon Williams showed in the spring just how electrifying he can be and brings an element of speed and explosion that will go hand-in-hand with quarterback Johnny Manziel's ability to break down defenses. Don't forget about sophomore Trey Williams. He was a big-time recruit coming out of high school, and Oregon transfer Tra Carson will also be eligible. Carson is pushing 230 pounds and will be the brute of the bunch. "They can all play anywhere, and that changes what we do," Sumlin said of his four backs.

Weakest position: Linebackers

There will be considerable change at the linebacker position for the Aggies in 2013. Gone are senior starters Sean Porter and Jonathan Stewart, and the only returning starter -- senior Steven Jenkins -- was limited this spring after tearing his labrum. What's more, the guy coaching the Texas A&M linebackers will be new. Mark Hagen is in his first season on the Aggies' staff after coming over from Indiana. Junior Donnie Baggs was a backup last season, but he's the likely starter in the middle. The unnerving part for the Aggies is that they will have to rely on a lot of newcomers at linebacker, but several of those guys showed real promise this spring. Junior college transfer Tommy Sanders can fly and looks like a natural for the strong side linebacker spot. True freshman Reggie Chevis enrolled early and also went through the spring. He's already 250 pounds and a real thumper in the middle. Brett Wade was another true freshman who went through the spring and got a lot of work on the weak side. With so many new faces, there could be some growing pains early at linebacker.
