Practice, he said, has taken on a different feel since the Nebraska game.
"We know we have to pick up the intensity and the conditioning to be honest with you," he said after practice today.
"The Nebraska game showed us that in these last few practices we have to pick up the tempo and the intensity, so that is what we are doing.
"During the game I don't feel like we were mentally focused which led to busted coverages. Our main thing is that when we are tired we have to stay mentally in the game. We lost that Saturday."
Confidence, he says, is something the Eagles have maintained into practice this week.
"We know we are a good secondary," he said. "The game, when we got tired, our technique faltered and that is our main focus, getting that back."
Walters said he was not pleased with his individual performance.
"The whole week we were gearing up to stop the run and really focused on the option game," he said. "We just didn't expect them to come out and throw the ball the way they did. I don't think anyone did.
"It was my first time playing in a big game and on that kind of a stage," he added. "I was nervous and really ramped up. My biggest thing is that I wasn't relaxing and I got caught up in the moment.
"After the game I knew I did not play well. The good news is that I am more relaxed and I know what to expect. It is going to be a great thing in the long run, it will make me a better player."
Walters said the mood of the team is very upbeat. There are leaders on this team that will not allow them to dwell on a loss.
"We have a full season in front of us, everyone is working toward the goal of winning a conference championship," he said. "We are very positive, and are focused on working harder than ever."
Walters named a few keys for the secondary going forward.
"We have to tackle better," he said. "Conditioning is a key and playing hard through the 4th quarter is what we'll need to do to finish. We've learned a lot that first game, and we are ready to be a better team because of it."
