Notre Dame defensive end Kapron Lewis-Moore put it best when the difference between home and road victories was brought up to the senior.

"That's the No. 1 question this week," Lewis-Moore said.

With every game ending in a win, it is not a major concern for the No. 4 Irish (8-0) as they prepare to play host to Pittsburgh (4-4) on Saturday, but there has been a stark difference to the final scores inside and outside of Notre Dame Stadium.

The Irish have won each home game by an average margin of 5 with no win being more than 7 points.

But away from Notre Dame Stadium, the Irish are winning games by an average margin of 28 points with no win coming by less than 17 points.

"I don't know," Lewis-Moore said of why the margin of victory is so much larger away from home. "I don't think we are playing different or anything like that. You could say a lot of things. I don't if it's the music, if it's the whole 'us vs. the world' mentality, we just play every week. I guess being mentally and physically tough in the fourth quarter goes a long way and being mature and handling the crowd noise on the road and everything."

Coach Brian Kelly offered a theory for why the Irish home games have been so close, and that is because opponents get revved up to play in Notre Dame Stadium and are at their best on the Irish's home field.

Lewis-Moore agreed with Kelly's theory to a point, but he believes no matter the venue, the Irish are always going to get another team's best.

"I think every team is going to come out 100 percent because we are Notre Dame, and you know, everybody wants to beat Notre Dame. You hate Notre Dame. You love Notre Dame. The whole whatever … I think every week, you are going to get everybody's best game," Lewis-Moore said.
