USC's defense had a disappointing 2025 season, with the defensive line, linebackers, and cornerbacks all underperforming. The safeties were the bright spot, led by Consensus All-American Bishop Fitzgerald. With several key players departing, new defensive coordinator Gary Patterson will have his work cut out for him as he looks to improve the Trojans' defense in 2026.

Why it matters

USC's defense was a major factor in the team's struggles in 2025, as they were unable to make key stops in critical moments against opponents like Illinois, Oregon, and TCU. The performance of the defense will be crucial in determining the trajectory of the Lincoln Riley era at USC, as the Trojans look to bounce back and contend for a Big Ten title in 2026.

The details

The defensive line received a 'B' grade, with Eric Henderson's unit failing to dominate the line of scrimmage against top opponents. The linebackers, led by Rob Ryan, earned a 'C-' as the unit struggled with missed tackles. The cornerbacks were the weakest link, earning a 'D+' due to injuries and poor performance. The safeties, anchored by Consensus All-American Bishop Fitzgerald, were the bright spot with a 'B+' grade.
