"Most of the mistakes we made against Georgia Tech were mental errors," he says.
The Tigers saw their 15-game winning streak ended as the Yellow Jackets took a 23-14 victory on Saturday night at Jordan-Hare Stadium. That loss isn't going to ruin the season, Obomanu says, but it is one that particularly irritates the older Tigers.
"It always hurts to lose a game," he says. "A lot of us have been through times when we lost before, but some of the younger guys have never lost a game here and it is new to them. It hurts the older guys a lot, especially losing to Georgia Tech again like we did in 2003."
On Saturday, the Tigers entertain Mississippi State at 11:30 a.m. for the SEC opener. Obomanu says his Tigers have plenty of work to do before then.
"The thing we have got to get ourselves prepared to do is to become a disciplined team," he says. "That means staying on side, making the right reads, making the right blocks and running the right routes. It's on everybody. It's the whole team collectively."
Obomanu scored one of Auburn's two touchdowns in the opener.
The fact that Saturday's contest is a conference game makes it even bigger, the senior wide receiver says. "It gives you an added incentive knowing it is an SEC game. Every SEC team's ultimate goal is to make it to the SEC Championship Game and win there and our goal is to repeat. We had a taste of what it feels like to get to Atlanta and win."
Obomanu says the loss to Tech hurts, but adds, "At the same time it lets us know that we have to work even harder to prepare for the next game. I think we will bounce back. In the first game you are always going to have good and bad, but at the same time we realize we all have things to work on. Nobody is where they want to be."
