The former walk-on from Carrollton, Ga., is the grandson of former Tiger standout Jimmy Morrow, who played on Auburn's 1957 national champions.
Asked if he was nervous, Harris said, "We practice situations like that all of the time and we had been asked that early in the week what would happen if it came down to a kick to win the national championship. We knew we would be ready.
"I couldn't think of a better way for the game to end with us to have the game on our hands and come through with the winning field goal," Harris said.
Caudle, a fifth-year senior, agreed with Harris and said, "I wasn't nervous at all on the last play. That is what we have worked on all year. We wanted the pressure to win the game and were ready for it."
Harris said it was truly a thrill to be able to play in the BCS National Championship Game. "It is an incredible stage," he said. "To come out on top in a game like this means the world to our team."
The deep snapper said it certainly means a lot to him because when he arrived he wasn't sure he would even get to play for the Tigers. "Three or four years ago I never dreamed I would be in this spot," Harris said. "Knowing that I now get to call myself a national champion and I was part of the winning play for that national championship is unbelievable.
"It is really, really special to me that I was able to do something my grandfather did," Harris added. "He was on the 1957 team. You can't write it any better than that. I know he is proud of me."
