The Fighting Irish, now 12-0, beat USC 22-13 Saturday night to earn a berth in the title game.
After the game they boarded a flight and returned to campus around 6 this morning. But the early hours didn't stop their fans from welcoming the team home. As the team buses pulled onto campus dozens of fans started cheering at the top of their lungs.
Notre Dame Student Maria McGuire was one of those cheering.
"It's just so exciting that we're number one and we're going to the National Championship game," said McGuire.
