Brian Kelly admitted he was an engineer of the "Crazy Train" that pulled into Notre Dame Stadium on Saturday. The Ozzie Osbourne song was played repeatedly when USC faced a third down, which was a radical departure from the typical game-day experience. 

On Wednesday, the Notre Dame coach said there's more changes he would like to make.

"We want to get better at it," Kelly said. "We felt it was a good start for us in terms of atmosphere but eventually we want a big JumboTron in there. That's going to be something that adds to the atmosphere, too." 

Kelly seemed to be half kidding. But he has never made a secret of wanting to replace the natural grass with artificial turf.

"It won't be my decision to make," he said. "I can only give you my thoughts and I've sprinkled that in in the conversation. I don't think it's a mystery. We would like that but it's not going to be my call. They know how I feel."
