"We've got a bad taste in our mouths," he said. "We've got to get back to work tomorrow, watch film and get better. We'll go back tomorrow and watch film and make changes and get back on track."
Fannin had three carries for eight yards and caught three passes for 56 yards and a touchdown against the Commodores. He said Vanderbilt's defense played well, but admitted Auburn made many mistakes in the second half.
"We beat ourselves," he said. "We let up after the first half. We started out good, but we had a wrinkle and they came out and got their confidence back in them. We've got to work on that, coming out and getting after it. They put more in the box.
"Hopefully, we can make some changes," Fannin said. "It's small things really. That's what basically hurt us tonight is the small things."
Auburn's offense racked up 126 yards in the first quarter, but faltered after Vandy's defense made some adjustments later in the game. The Tigers made just three first downs in the second half. Fannin said Vanderbilt started putting more men in the box and bringing the safeties up.
"They are a great team," he said. "They played good defense. We‘ve got to make changes and get back on track. We didn't play that well on offense in the second half. We made some errors as far as blocking and some things of that nature so we've got to make some changes and get back on track."
Auburn's offense started the game rushing almost every down with success. When quarterback Chris Todd tried to pass, things didn't work out so well. Fannin said he didn't know why Auburn stopped running the ball.
"Actually, I really don't," he said. "I don't have an answer for that."
He was also surprised that Vanderbilt won. Despite Auburn's offensive struggles this season, Fannin said he never dreamed Auburn would fall to the Commodores.
"I really am (surprised), but Vanderbilt played great," he said. "They made some plays, and we didn't come out in the second half and make plays ourselves so they came out on top."
Fannin said the offensive players didn't get down when the game seemed to be slipping away from them, but they were trying to pull together and make something--anything--positive happen.
"We were trying to find some kind of inspiration to get us back up," he said. "We weren't down. We tried to pick our intensity back up. The defense did a great job of making some stops. The offense tried to make some things happen. Unfortunately we couldn't."
Fannin said he has never experienced anything like this before as an Auburn player, but is confident Auburn will correct its offensive woes.
"We'll get it fixed," he said. "We'll get it fixed. We've just got to get the small things done. We'll start with film and break down the film and see what we did wrong. It can get frustrating, but you've got to blow it off and keep playing the game. Anything can happen. You just have to play ball."
