By this point, just three days before the season opener, Kirby Smart has seen plenty of tape on Appalachian State. And the Georgia football coach noticed one particular thing when he watched the Mountaineers’ defensive highlights: tremendous speed.

“They play with incredible speed, toughness, tenacity,” Smart said Wednesday during the first SEC teleconference of the season. “They recruit to a certain type player, and that player is fast.”

The Bulldogs have a young, inexperienced offensive line this season, and those players will have an interesting challenge ahead of them in the opener. Appalachian State doesn’t have especially large players on the defensive line, but rather linemen who use finesse and quickness while attempting to get to opposing teams’ quarterbacks.

“You’ve got to be careful about putting them in 1-on-1 situations, those guys use quickness,” Smart said. “Those guys do a tremendous job, and it creates a little bit of a disadvantage sometimes for your offensive line. … They slash, they tackle for a loss, they’re very disruptive in what they do.”

Georgia and Appalachian State open the season at Sanford Stadium Saturday at 6:15 p.m. ET on ESPN.
