That ended a streak of 13 quarters without allowing an opponent to cross the goal line. However, Gibbs said there was plenty of good to come out of Saturday's homecoming victory over Western Kentucky.
Defensive end Marquies Gunn gets one of Auburn's three sacks on the day.
"You are never satisfied, but I think we are making improvements," Gibbs said. "You would like to keep these guys out of the end zone, but this is football and that is hard to do because everybody is on scholarship and there are good teams and good coaches all over the country on every level.
"We have to find a way to keep people out of the end zone. What matters now is to find a way to keep South Carolina out of the end zone next week.
"Overall, I thought our starters did a decent job," Gibbs added. "Then, I thought our young guys went in there and screwed around a little bit on defense. I was pleased with the first half and then we got sloppy in the second half. Obviously, I am disappointed with that, but at least we got some guys some playing time."
One of the guys who got some playing time, walk-on cornerback Zach Gilbert, a fourth stringer, took advantage of the chance to play with an interception in the end zone in the fourth quarter.
"He made a nice play and I thought he was going to run it back for a touchdown for a second, but it looked like he ran out of gas there," said Gibbs, who doubles as secondary coach.
