Lincoln Riley's Trojans suffered another defensive collapse

Despite a heroic effort from Heisman Trophy winner Caleb Williams, the USC Trojans suffered yet another stunning defensive collapse in a 46-45 loss to Tulane in the Cotton Bowl on Monday.

Williams threw for 462 yards and five touchdowns, but USC's defense couldn't hold a 45-30 lead, allowing two Tulane touchdowns in the final 4:07 of the game. The game-winning touchdown came on a six-yard touchdown pass from Michael Pratt to Alex Bauman with 9 seconds to play.

No. 10 USC (11-3) finishes its first season under Lincoln Riley with back-to-back losses, while No. 16 Tulane (12-2) ends on a high note.
