Lincoln Riley has a mess on his hands.

The Trojans were out-played, out-coached, out-muscled, and undone Saturday night in South Bend. In a 48-20 loss to Notre Dame, Lincoln Riley suffered the worst loss of his head coaching career and saw his offense have the single worst day a Riley-led unit has had since 2015.

USC suffered its first loss of the season, yes. The conference record is still 4-0, yes. But the Trojans have looked flawed for weeks and those shortcomings on offense were laid bare for all to see by an Irish defense that just took it to USC.

Quarterback Caleb Williams threw three interceptions, completed just 62% of his passes, and totaled only 191 yards of offense. He pressed and made mistakes.

USC fumbled it away on its last two possessions to finish with more turnovers against Notre Dame (five) than it had in the previous six games (four).

After the game, Riley was lit up on social media.

Here’s some of the reaction:
