Auburn didn't only add a surefire starter in Wilson Bell, the graduate transfer offensive guard is a behemoth.

Bell, who was listed at 6-foot-5 and 320 pounds at Florida State, is listed at a team-high 355 pounds at Auburn, where he is expected to start at right guard. That's more than 50 pounds heavier than right tackle Braden Smith (303).

"Wilson Bell is our mountain of a man," Auburn coach Gus Malzahn said. "He's big. We recruited him really hard when we first got here in 2013. So to have him added to what we've got, that's a big help."

Bell started five games at right guard at Florida State last season and every game in 2015.

With Smith moving from guard to tackle, Bell is in line to take over at right guard and has been taking reps there during offseason work since arriving on campus earlier this summer.

"He's been getting some guards reps mainly, primarily, because that's where he played at Florida State," Smith said. "We kind of have to see how it all goes in (fall camp) and once we put on pads, but he's been picking up the offense really well, learning, going through all the drills (and) getting up to pace with us."

With the addition of fellow graduate transfer Casey Dunn, Auburn's offensive line could see a dramatic change from even the end of spring practice.

Dunn, an All-American at Jacksonville State, has been working at center this summer along with Austin Golson, so it'll remain to be seen if one of them moves to left guard before the season or if Mike Horton remains at the top of the depth chart there.

Malzahn feels the depth on Auburn's offensive line is "as good as it's been" in a long time.

Smith concurred.

"The depth, that's really a key factor in our success going forward, knowing we got guys that can be plugged in and just play," Smith said. "We don't have guys that can play just one spot; they can play right guard, right tackle, center, left guard, left tackle."
