The 35 points allowed to Auburn added almost three points to the scoring defense average for Ole Miss.
The Rebels still lead the nation, but the gap is much less wide.
Ole Miss is giving up 13.2 points a game.
Three of the top four scoring defense teams are in the SEC, and the Rebels are followed by Alabama (14.0 ppg), Wisconsin (14.1 ppg) and LSU (15.9 ppg).
The top 10 is rounded out by Houston, Stanford, Marshall, Louisville, Penn State and Clemson.
The Rebels have given up 517 rushing yards in losses to LSU and Auburn over the last two weeks.
Defensive coordinator Dave Wommack believes his unit will play better in the games ahead, though getting up after such an emotional home loss to Auburn will not be easy, he concedes.
“That will be the challenge, absolutely. We’ve had a difficult stretch. I think defensively we’ve especially played pretty well until tonight,” he said following the game. “I think our guys have a lot of pride, and they’ll bounce back. We’ll have to. We still have a lot of things to play for, and as good as this league is you never know what’s going to happen.”
