Theo Riddick ran 18 times for 104 yard and caught six passes for 67 more for the Irish, who are 10-0 for the first time since 1993.
That was the year BC's David Gordon kicked a 41-yard field goal as time expired in the final game to beat No. 1 Notre Dame and end its hopes for a perfect season. In 2002, the Irish were unbeaten and No. 4 in the country when unranked Boston College won 14-7 in South Bend to again spoil Notre Dame's chances at a national championship.
"It's Notre Dame. Everyone knows them when you're growing up," Rettig said. "Everyone says play each game the same, but that doesn't stand true when you're playing Notre Dame. It's an exciting game to get ready for, especially when playing at home. The stadium is packed. They don't think it's a rivalry, but we still have that sense."
But there was no upset this year in the matchup between the only two Catholic schools in the FBS, a game that drew the first sellout crowd of the season on a frigid night in Chestnut Hill.
In fact, it wasn't even as close as Notre Dame's victory over Pitt, or the four other games the Irish have won by a touchdown or less, keeping them near the top of The Associated Press rankings with an outside chance at a spot in the BCS title game.
"We're going to worry about winning," Notre Dame coach Brian Kelly said. "If people don't like us winning, there's nothing we can do."
Notre Dame entered the day trailing Alabama, Oregon and Kansas State in the AP Top 25; the Irish would probably need either Oregon or Kansas State to fall from the unbeaten in order to squeeze into the top two in the BCS rankings.
