USC May Finally Have The Defense Lincoln Riley Has Needed

Lincoln Riley's new defensive game plan, bolstered by the addition of Hall of Fame coach Gary Patterson, aims to transform USC into a top contender this season.

Lincoln Riley thinks USC is in a different place defensively now, and he didn’t try to soften the point.

After years of watching elite offense get dragged down by breakdowns on the other side of the ball, Riley said the Trojans finally have more to work with across the roster. He pointed to the mix of returning starters, freshmen and transfer additions as the reason for his confidence heading into the season.

“I do feel differently this year in terms of the quality of players, returning starters, the freshmen, some of the transfers that we've added,” said Riley during Big Ten Media Days. “There's just a ton of competition.

We have a lot of guys on both sides of the line of scrimmage that we feel like we can win with and dominate with. We just do.”

That belief is tied directly to the arrival of Gary Patterson, who stepped in as defensive coordinator in January after being inducted into the College Football Hall of Fame. Riley made it clear Patterson has already changed the tone around the program.

“it's tougher to move the ball in practice,” said Riley at Big Ten Media Day of the difference Patterson is already making. “Coach Patterson is one of one … I've never coached against somebody that I thought was more unique and tougher to go against than Gary.”

Patterson’s résumé explains why USC wanted him in the building. Over 21 seasons at TCU from 2000-2021, he won 181 games, became the school’s all-time winningest coach, led 11 teams to at least 10 victories and directed defenses that finished first nationally in total defense five times.

The Trojans are also bringing back six defensive starters and adding more talent through high school recruiting and the transfer portal, which is part of why Riley says this group feels more complete than the ones before it.

“I certainly will give you what has changed, is I do believe we're more equipped than at any point in the previous few years,” Riley said. “That's not a hope or a wish. Those are facts, and there's a lot of facts to back that up.”

That confidence comes after a stretch where USC’s defense has been the program’s biggest problem. The Trojans finished outside the top 90 nationally in scoring defense in 2022, then outside the top 120 in both scoring and total defense in 2023 before making progress over the past two seasons under D'Anton Lynn.

Even with that improvement, one issue kept showing up in 2025: the run defense away from home.

“We did not stop the run enough on the road,” said Riley of the Trojans' 2025 defensive performance.

The numbers back him up. USC gave up 121.3 rushing yards per game at home, but that jumped to 168.8 on the road and at neutral sites. Opponents averaged 4.63 yards per carry away from Los Angeles, compared with 4.06 at home.

The problem got worse in USC’s four losses, when opponents ran for 193.3 yards per game at 5.12 yards per carry and scored 10 rushing touchdowns.

That’s the kind of weakness Patterson was brought in to fix. His reputation was built on physical, disciplined defenses at TCU, and USC is betting that profile can help turn a long-standing liability into something much sturdier.

The impact is already being felt beyond the defensive room. USC defensive tackle Alex VanSumeren said Patterson’s presence has changed the mindset around the program.

“He's in the Hall of Fame for a reason. He could have stayed retired, could have kept golfing, but he came back because he loves the game and he wants to win,” said USC defensive tackle Alex VanSumeren. “He's told us many times, he didn’t come back for anything but to win.”

Quarterback Jayden Maiava has noticed it too, and he likes what Patterson’s scheme is doing for the offense in practice.

"Credit to GP (Gary Patterson). He just sets the standard, and he sets the mindset and the mentality that he wants for his defense, and everybody's along, and everybody's on the same page,” said Maiava.

“It was really cool going against him during spring. I'm really excited for that to be showcased on Saturdays."

That daily work matters for Maiava, who threw for 3,711 yards and 24 touchdowns in 2025 but also had 10 interceptions. Facing Patterson’s disguises, late safety rotations and pre-snap pressure every day should force him to process faster before USC gets into the thick of its schedule.

And the schedule is no joke. ESPN’s Football Power Index has USC with the 19th-toughest strength of schedule in the country, with Ohio State, Oregon, Penn State and Washington all on the slate.

Riley has spent the past year building a roster he believes can compete with anybody. Now he’s leaning on Patterson to make sure the defense finally matches the rest of it.

USC Is In A Real Fight For Elite California Linebacker

Southern Cal has stayed active with Landon Miller, and the four-star linebacker has given the Trojans plenty of reason to keep pushing. The California standout has been on campus for an unofficial multi-day visit, worked out on the field, studied film, toured campus and met with Lincoln Riley, Chad Bowden, Max Stienecker and linebackers coaches AJ Howard and Mike Ekeler, all while remaining one of the nations most closely watched defensive recruits.

Millers recruitment is still wide open, with USC in the mix against several blue-blood programs and more visits on the calendar. He plans to be at the Trojans Sept. 12 game against Louisiana, then head to Oregon for its matchup with UCLA, with additional trips to other contenders still possible as he keeps sorting through a decision that could shape the West Coast linebacker market.

Drake London Is Paying The Price For Something He Cannot Fix

Drake Londons name came up again in a familiar kind of conversation this week, the sort that says as much about circumstance as it does about talent. League executives and coaches left the former USC standout just outside the top 10 NFL receivers list, slotting him as an honorable mention instead, even though his profile keeps growing in ways that are hard to ignore.

One NFL coordinator described London as a solid possession receiver who wins contested catches and shows up in the red zone, but also pointed to the limitations around him in Atlanta. For USC fans who watched him develop into a polished playmaker, the frustrating part is how much of his ceiling still seems tied to factors he cannot control, leaving his reputation a step behind his ability.

USC Defender Is Giving Lincoln Riley A Reason To Believe Up Front

Jide Abasiris offseason became one of those quiet USC developments that can matter a lot once the pads come on. The defensive lineman arrived at the 2026 Big Ten Media Days talking less about depth-chart noise and more about the work he put in away from it, stressing personal development, confidence and the kind of day-to-day commitment that coaches notice long before the box scores do. Lincoln Riley has already singled out Abasiris dedication to the program, a meaningful nod for a player trying to carve out a bigger role up front.

Abasiri also offered a glimpse into the mindset that has shaped his path, including the way his Nigerian heritage has influenced his football journey. For USC, that matters because the Trojans are looking for more than just bodies on the defensive line - they need players who can grow into reliable pieces in a demanding league. Abasiri sounds like someone intent on being that kind of presence, even if the bigger test of how far he has come is still ahead. [Read more 🡒]
